WEBVTT 00:00:05.129 --> 00:00:06.849 All right, everyone, thank you so much for joining 00:00:06.849 --> 00:00:09.470 us once again on Did You Know? You know, we spend 00:00:09.470 --> 00:00:11.550 a lot of time talking about the A2L transition, 00:00:11.990 --> 00:00:14.529 especially in the residential side and the mitigation 00:00:14.529 --> 00:00:16.449 controls and the strategies that we're going 00:00:16.449 --> 00:00:19.190 to be using for residential applications. But 00:00:19.190 --> 00:00:20.690 we don't always talk a lot about what's happening 00:00:20.690 --> 00:00:22.809 in the commercial side, whether it's in commercial 00:00:22.809 --> 00:00:26.769 HVAC or it's in the refrigeration sector. And 00:00:26.769 --> 00:00:28.730 there's a lot of questions in the industry. A 00:00:28.730 --> 00:00:30.629 lot of people are concerned with refrigerants. 00:00:31.079 --> 00:00:33.359 And we're just trying to break those fears because 00:00:33.359 --> 00:00:34.939 there's not a lot of fear involved with this. 00:00:35.000 --> 00:00:37.320 It really comes down to just education. It's 00:00:37.320 --> 00:00:39.460 not our first refrigerant transition. You know, 00:00:39.460 --> 00:00:44.159 it's just another rodeo. And so we need to help 00:00:44.159 --> 00:00:46.299 educate the industry on what's happening. So 00:00:46.299 --> 00:00:48.060 I'm very fortunate to spend some time with Johnson 00:00:48.060 --> 00:00:52.399 Controls to talk about solutions for our A2L 00:00:52.399 --> 00:00:55.539 detection as well as mitigation strategies and 00:00:55.539 --> 00:00:58.380 hopefully keep this industry as simple as possible 00:00:58.380 --> 00:01:00.759 because we don't need a thousand control. and 00:01:00.759 --> 00:01:03.820 a thousand strategies, we can use intelligent 00:01:03.820 --> 00:01:06.840 controls to be able to simplify all of it. And 00:01:06.840 --> 00:01:09.379 this is a very intriguing product. And I just 00:01:09.379 --> 00:01:11.000 think we ought to be able to help the industry 00:01:11.000 --> 00:01:13.739 understand what's available to them and how easy 00:01:13.739 --> 00:01:17.280 this whole A2L transition can be. Yeah, absolutely. 00:01:17.799 --> 00:01:20.180 All right. So let's walk me through where we're 00:01:20.180 --> 00:01:24.079 at as far as mitigation controls and what the 00:01:24.079 --> 00:01:26.719 solution provides us. Sure. I'd be glad to. And 00:01:26.719 --> 00:01:31.370 I think the key word here is smart or intelligent 00:01:31.370 --> 00:01:36.510 controls that help with serviceability. This 00:01:36.510 --> 00:01:39.590 is Johnson Controls under the Penn brand name, 00:01:39.709 --> 00:01:43.530 newest modular electronic control system called 00:01:43.530 --> 00:01:47.370 System 550. The module on the left -hand side 00:01:47.370 --> 00:01:50.150 here is the control module. This is where all 00:01:50.150 --> 00:01:53.109 the brains are. the module in the middle is simply 00:01:53.109 --> 00:01:55.989 a transformer it's a power supply sure so it 00:01:55.989 --> 00:01:59.209 provides the 24 volts either ac or dc that's 00:01:59.209 --> 00:02:03.189 needed to power the electronics and then we we're 00:02:03.189 --> 00:02:05.689 not using it in this particular application that 00:02:05.689 --> 00:02:08.530 i have configured but the last module here is 00:02:08.530 --> 00:02:11.189 what's called an expansion module and it will 00:02:11.189 --> 00:02:14.150 provide either two more relay outputs or you 00:02:14.150 --> 00:02:17.030 could have an expansion module that will provide 00:02:17.030 --> 00:02:19.610 two analog outputs so you can have a combination 00:02:19.610 --> 00:02:23.330 of relay and analog outputs up to a total of 00:02:23.330 --> 00:02:26.770 10 outputs okay yeah but to talk specifically 00:02:26.770 --> 00:02:30.750 about a2l leak detection and mitigation this 00:02:30.750 --> 00:02:33.689 is a full functioning control meaning that it 00:02:33.689 --> 00:02:38.729 supports both single and multi -stage with temperature 00:02:38.729 --> 00:02:43.330 humidity and pressure sensor inputs as well as 00:02:43.330 --> 00:02:47.139 it has the full capabilities of A2L leak detection 00:02:47.139 --> 00:02:49.879 and mitigation. What I mean by full capabilities 00:02:49.879 --> 00:02:54.819 is that the controller in the sensor and this 00:02:54.819 --> 00:02:58.159 is an example of the sensor in combination are 00:02:58.159 --> 00:03:01.659 considered an RDS or refrigerant detection system. 00:03:01.780 --> 00:03:03.979 Absolutely. So they have all of the requirements 00:03:03.979 --> 00:03:09.819 that are under UL 60335 both dash 2 dash 40 and 00:03:09.819 --> 00:03:15.490 dash 289 to qualify as an RDS. 40 and 89. So 00:03:15.490 --> 00:03:17.650 technically this could even be used in a residential 00:03:17.650 --> 00:03:20.930 style application if need be. Oh, wow. And so 00:03:20.930 --> 00:03:22.669 with the modular, now I'm starting to see what 00:03:22.669 --> 00:03:25.289 you meant by modular. So this is actually a full 00:03:25.289 --> 00:03:27.990 control network and it's expandable for the amount 00:03:27.990 --> 00:03:29.990 of outputs that we would need to be able to control. 00:03:30.370 --> 00:03:34.509 That's right. Not only that, but the backplane 00:03:34.509 --> 00:03:39.250 is communicating from the controller to the expansion 00:03:39.250 --> 00:03:43.229 modules via Modbus. and that's what gives us 00:03:43.229 --> 00:03:46.129 the intelligent A2L leak detection and mitigation 00:03:46.129 --> 00:03:50.009 because it's doing a handshake with one or more 00:03:50.009 --> 00:03:54.729 A2L sensors so it knows you can see on this particular 00:03:54.729 --> 00:04:00.930 sensor here that the refrigerant type R454A is 00:04:00.930 --> 00:04:05.189 marked on the sensor the OEM that integrates 00:04:05.189 --> 00:04:08.050 this into their equipment will also select the 00:04:08.050 --> 00:04:10.289 refrigerant that they're using and it's going 00:04:10.289 --> 00:04:12.930 to do a handshake with a sensor to make sure 00:04:12.930 --> 00:04:16.350 that you've plugged in the right sensor so it's 00:04:16.350 --> 00:04:18.129 a communicating network and it's a communicating 00:04:18.129 --> 00:04:22.589 network correct no joke so if if i have a large 00:04:22.589 --> 00:04:25.170 piece of equipment maybe it's a package rooftop 00:04:25.170 --> 00:04:28.889 system and i have to use multiple sensors i will 00:04:28.889 --> 00:04:31.790 also in addition to selecting the refrigerant 00:04:31.790 --> 00:04:34.410 type i'll select the number of sensors that i 00:04:34.410 --> 00:04:39.470 use and our particular controller is set the 00:04:39.470 --> 00:04:42.709 factory setting or the digital trip point on 00:04:42.709 --> 00:04:46.990 the A2L is a 20 % LFL. Yeah, sure. Or a lower 00:04:46.990 --> 00:04:51.089 flammability limit. You bet. If you want to warm 00:04:51.089 --> 00:04:54.629 below that, you also have the capability with 00:04:54.629 --> 00:04:58.310 this controller to actually set a... lfl level 00:04:58.310 --> 00:05:01.149 lower than that digital trip point for a different 00:05:01.149 --> 00:05:03.569 alarm set point we have a lot of customers that'll 00:05:03.569 --> 00:05:07.649 want 15 10 give me an initial warning yeah so 00:05:07.649 --> 00:05:11.399 we know what's going on so yeah it's pretty flexible 00:05:11.399 --> 00:05:13.660 there and how you want to set up your system 00:05:13.660 --> 00:05:16.639 you know i see this as a solution not just for 00:05:16.639 --> 00:05:18.920 the equipment that is going to be for either 00:05:18.920 --> 00:05:21.680 hvac or refrigeration but we've had a lot of 00:05:21.680 --> 00:05:24.819 questions and concerns from say hydronic you 00:05:24.819 --> 00:05:26.560 know boiler manufacturers that are operating 00:05:26.560 --> 00:05:29.360 in the same mechanical room as an a2l say an 00:05:29.360 --> 00:05:31.899 a2l air handler and they want to make sure that 00:05:31.899 --> 00:05:35.060 they control their ignition controls on their 00:05:35.060 --> 00:05:38.089 device well now it becomes a simple modular component 00:05:38.089 --> 00:05:40.449 that could be introduced into any application 00:05:40.449 --> 00:05:43.589 as a standalone A2L mitigation strategy. Yeah. 00:05:43.730 --> 00:05:47.589 And this has the capability of doing staging, 00:05:47.850 --> 00:05:51.629 runtime optimization, so that it actually is 00:05:51.629 --> 00:05:54.230 smart enough to know if I have a modular boiler, 00:05:54.490 --> 00:05:56.910 you know, several. Right. And I turn boiler one 00:05:56.910 --> 00:05:59.810 on and let's say it stays on for an hour. Next 00:05:59.810 --> 00:06:03.259 time I have a call for heat. I'm going to turn 00:06:03.259 --> 00:06:05.300 boiler number two on and I'm going to record 00:06:05.300 --> 00:06:09.379 that amount of time on the controller. Wow, from 00:06:09.379 --> 00:06:11.600 an engineering aspect, that really simplifies 00:06:11.600 --> 00:06:15.360 the build of it because now we can use a single 00:06:15.360 --> 00:06:17.980 control in a mechanical room for a variety of 00:06:17.980 --> 00:06:20.500 different equipment functions. I don't think 00:06:20.500 --> 00:06:23.939 you're going to find too many controllers with 00:06:23.939 --> 00:06:28.319 this much functionality at this price point. 00:06:28.639 --> 00:06:31.379 okay and it's interesting we start talking about 00:06:31.379 --> 00:06:34.160 communicating so we have a communicating sensor 00:06:34.160 --> 00:06:37.819 as part of the control itself is that something 00:06:37.819 --> 00:06:41.759 that can be monitored remotely then yes so every 00:06:41.759 --> 00:06:44.500 one of the controllers the chipset that we're 00:06:44.500 --> 00:06:48.759 using is broadcasting a local wi -fi signal really 00:06:48.759 --> 00:06:52.399 so i can actually upload new firmware to the 00:06:52.399 --> 00:06:58.629 device through a local wi -fi i can also download 00:06:58.629 --> 00:07:02.949 and upload config files. So let's say today, 00:07:03.110 --> 00:07:06.529 if I'm in a manufacturing environment, I want 00:07:06.529 --> 00:07:10.769 to manufacture the same commercial refrigeration 00:07:10.769 --> 00:07:14.009 equipment. And I don't want to, you know, turn 00:07:14.009 --> 00:07:16.790 the knob and configure each device individually. 00:07:16.810 --> 00:07:21.350 I can configure what I want as a config, you 00:07:21.350 --> 00:07:23.949 know, configuration. And then I can download 00:07:23.949 --> 00:07:27.870 that through Wi -Fi. Copy it. to my to my pc 00:07:27.870 --> 00:07:31.670 yep right and then in a production environment 00:07:31.670 --> 00:07:36.970 i can take a usbc cable and i can plug it in 00:07:36.970 --> 00:07:40.569 to this usbc port and because i'm getting power 00:07:40.569 --> 00:07:44.069 from my computer i don't even have to power the 00:07:44.069 --> 00:07:46.170 control system oh it can be standalone because 00:07:46.170 --> 00:07:48.709 it's getting power from the usb cable i can program 00:07:48.709 --> 00:07:50.790 this at the shop and have it ready to go to send 00:07:50.790 --> 00:07:57.110 out on the job all of my um my modules and I 00:07:57.110 --> 00:07:59.829 can have them programmed, pre -programmed without 00:07:59.829 --> 00:08:01.990 even powering them. Now we're getting somewhere. 00:08:02.329 --> 00:08:04.550 Through the computer. Wow, you put a lot of thought 00:08:04.550 --> 00:08:07.129 and design into this. Well, a lot of customer, 00:08:07.430 --> 00:08:10.610 voice of customer. Yeah, a lot of industry input. 00:08:11.290 --> 00:08:14.790 So it's a little bit difficult to see here, but 00:08:14.790 --> 00:08:17.750 if you take a look on the right side of this 00:08:17.750 --> 00:08:21.069 last module, which is the expansion module, in 00:08:21.069 --> 00:08:24.079 this case, it's a relay expansion module. you 00:08:24.079 --> 00:08:27.639 can see where this controller, or this sensor 00:08:27.639 --> 00:08:30.819 rather, this A2L sensor is wired in. And this 00:08:30.819 --> 00:08:35.120 has physical room for two sensors to be connected. 00:08:35.700 --> 00:08:40.639 If I need to have more physical space for more 00:08:40.639 --> 00:08:44.360 A2L sensors, we have a modular similar to this, 00:08:44.360 --> 00:08:47.539 similar to these, that's called a junction wiring 00:08:47.539 --> 00:08:51.360 module. that will accommodate up to six a2l sensors 00:08:51.360 --> 00:08:54.620 no kidding so you know again those are things 00:08:54.620 --> 00:08:57.720 that when we first got our pre -production samples 00:08:57.720 --> 00:09:02.279 out and speaking with our oem customers like 00:09:02.279 --> 00:09:04.940 well in some cases we're going to need more than 00:09:04.940 --> 00:09:07.559 two sensors right so what can you do to accommodate 00:09:07.559 --> 00:09:11.019 us so simple add another module exactly add another 00:09:11.019 --> 00:09:13.440 module that's the that's the flexibility of this 00:09:13.440 --> 00:09:18.419 system what makes it nice is that From the technician 00:09:18.419 --> 00:09:21.940 standpoint, you can name the application, right? 00:09:22.240 --> 00:09:25.879 You understand what sensor in every application 00:09:25.879 --> 00:09:29.799 if there's an issue. So what's every tech want? 00:09:30.580 --> 00:09:33.460 Information before I go to the job site with 00:09:33.460 --> 00:09:37.080 what the problem is, where it is, and what I 00:09:37.080 --> 00:09:39.440 think I'm going to have to do or need with me 00:09:39.440 --> 00:09:41.559 before I get there. That's the best. So that's 00:09:41.559 --> 00:09:44.740 what it's really all about. So another feature 00:09:44.740 --> 00:09:47.100 that we've, and I'm going to demo it here, that 00:09:47.100 --> 00:09:50.980 we've incorporated in the control system is an 00:09:50.980 --> 00:09:53.320 equipment manufacturer, before they lock down 00:09:53.320 --> 00:09:55.240 their configuration, they're going to want to 00:09:55.240 --> 00:09:58.059 make sure, do I have all of my sensors wired 00:09:58.059 --> 00:10:01.700 correctly? Yeah. Do I have my A2L sensors configured 00:10:01.700 --> 00:10:07.240 correctly? And do I have my controller configured 00:10:07.240 --> 00:10:10.759 correctly? So we have a function here called 00:10:10.759 --> 00:10:14.820 test lock. which doesn't lock the controller 00:10:14.820 --> 00:10:18.980 down permanently sure it can be unlocked and 00:10:18.980 --> 00:10:23.500 then i can simulate here by a little tool that 00:10:23.500 --> 00:10:27.820 we have this has a program in it and so i'm simulating 00:10:27.820 --> 00:10:31.980 a sensor you can see here that this gas type 00:10:31.980 --> 00:10:35.799 is our 454a right what we looked at earlier so 00:10:35.799 --> 00:10:39.279 it matches what's configured here and now i right 00:10:39.279 --> 00:10:42.919 now if i had a sensor hook up to this which i 00:10:42.919 --> 00:10:45.879 i'm doing through the simulation right it says 00:10:45.879 --> 00:10:48.480 there's no leak present right but now what i 00:10:48.480 --> 00:10:51.080 can do is i can simulate oh i can introduce a 00:10:51.080 --> 00:10:54.700 leak not a percentage 10 and you'll see immediately 00:10:54.700 --> 00:10:58.159 that it comes up and it says i'm warning now 00:10:58.159 --> 00:11:02.049 at 10 and that warning light has now come on 00:11:02.049 --> 00:11:06.110 and so if i had programmed a 10 alarm i could 00:11:06.110 --> 00:11:08.889 actually be getting that first stage alarm right 00:11:08.889 --> 00:11:12.129 in test mode and if i were connected to the cloud 00:11:12.129 --> 00:11:14.769 right i could see it there i could see it on 00:11:14.769 --> 00:11:18.250 my mobile device absolutely in real time also 00:11:18.250 --> 00:11:21.629 keith about the light on here is it big enough 00:11:21.629 --> 00:11:24.269 can i put a light up big light up like an auxiliary 00:11:24.269 --> 00:11:28.039 on me strobe light at the application to be able 00:11:28.039 --> 00:11:31.720 to give me that in addition to wi -fi communication 00:11:31.720 --> 00:11:34.519 yeah wow so you will you will see it on the screen 00:11:34.519 --> 00:11:38.039 here but more importantly if you're remotely 00:11:38.039 --> 00:11:40.600 connected to the device through the cloud right 00:11:40.600 --> 00:11:44.759 you're going to see it 24 hours a day 365 days 00:11:44.759 --> 00:11:47.759 a year you're going to know the health of your 00:11:47.759 --> 00:11:49.840 equipment and whether or not the product that 00:11:49.840 --> 00:11:53.320 you're Trying to preserve is at the right temperature. 00:11:53.519 --> 00:11:55.419 So I'm assuming we're going to be so we're communicating 00:11:55.419 --> 00:11:59.059 Wi -Fi is there any type of like like RS -485 00:11:59.059 --> 00:12:02.360 that could be introduced into a standalone or 00:12:02.360 --> 00:12:04.759 an automated building management system? That's 00:12:04.759 --> 00:12:09.740 a really great question and a lot of Requests 00:12:09.740 --> 00:12:12.279 that we get so we are working on a module now 00:12:12.279 --> 00:12:16.500 That will actually tap in another module called 00:12:16.500 --> 00:12:19.399 a communication module. Yeah, absolutely You 00:12:19.399 --> 00:12:21.460 know this because you've been in the HVAC, our 00:12:21.460 --> 00:12:24.700 industry, for quite a while. On the refrigeration 00:12:24.700 --> 00:12:27.960 side, equipment there wants to speak my bus, 00:12:28.159 --> 00:12:31.379 right? On the building automation side or the 00:12:31.379 --> 00:12:34.440 HVAC side, most of the equipment is speaking 00:12:34.440 --> 00:12:38.659 BACnet, in our case, mostly MSTP. Oh, sure. Okay. 00:12:38.779 --> 00:12:43.340 So we are working on a communication module that 00:12:43.340 --> 00:12:45.820 will allow you to basically take all the data. 00:12:46.509 --> 00:12:49.809 that's coming from the control module and pass 00:12:49.809 --> 00:12:53.750 that along to either your supervisory controller 00:12:53.750 --> 00:12:58.509 or some type of auxiliary controller. I think 00:12:58.509 --> 00:13:01.149 as a contractor, if I'm an installing contractor, 00:13:01.570 --> 00:13:04.629 I kind of want both abilities. I want to be able 00:13:04.629 --> 00:13:09.269 to have my cloud access, particularly if I could 00:13:09.269 --> 00:13:13.049 set this at a 10%. If I'm a contractor... I don't 00:13:13.049 --> 00:13:15.169 want the building management system going into 00:13:15.169 --> 00:13:17.470 an alarm that maybe somebody doesn't even know 00:13:17.470 --> 00:13:21.049 when it hits 20%. If I could do a cloud recognition 00:13:21.049 --> 00:13:25.289 at 10%, I can dispatch, show up on site going, 00:13:25.429 --> 00:13:28.029 I've got an alarm on my side that I'd like to 00:13:28.029 --> 00:13:32.009 take a look at before we get anything. Yeah, 00:13:32.049 --> 00:13:35.409 that's really nice. So now I'm at 10 % and I'm 00:13:35.409 --> 00:13:37.970 warning because the light's on here. And then 00:13:37.970 --> 00:13:42.009 if I take it to 25%, which is above my trip point, 00:13:42.620 --> 00:13:45.779 You can see now that I've actually gone into 00:13:45.779 --> 00:13:48.019 mitigation. Okay. Okay, what does that mean? 00:13:48.159 --> 00:13:52.039 Well, I've turned my compressor off. Right. And 00:13:52.039 --> 00:13:56.240 I'm turning my evap fans on. Get circulation. 00:13:56.279 --> 00:13:59.539 To dissipate the concentration of refrigerant 00:13:59.539 --> 00:14:03.659 to get it below that 20 % LFL trip point. Absolutely. 00:14:03.679 --> 00:14:08.440 I'm going to now clear. So I'm going to basically 00:14:08.440 --> 00:14:14.120 assume now. That leak has stopped or at least 00:14:14.120 --> 00:14:16.360 the amount of refrigerant has leaked out and 00:14:16.360 --> 00:14:19.200 I've dissipated it. And now I'm going to clear 00:14:19.200 --> 00:14:22.700 my leak. And now you can see that I've gone into 00:14:22.700 --> 00:14:26.639 a countdown. Right. By the UL standard. Yeah. 00:14:26.740 --> 00:14:30.240 I have to keep it in basically this kind of wait 00:14:30.240 --> 00:14:32.480 mode. Yeah. For five minutes. Yeah, absolutely. 00:14:32.720 --> 00:14:34.820 Transitional soft lockout mode. The new firmware 00:14:34.820 --> 00:14:37.879 that we have will actually count this down. right 00:14:37.879 --> 00:14:40.340 now i have to just kind of wait wait for it five 00:14:40.340 --> 00:14:44.159 minutes yeah once it's done then i can confirm 00:14:44.159 --> 00:14:47.059 the alarm and it will go back into its normal 00:14:47.059 --> 00:14:49.919 mode you know one of the things that i've seen 00:14:49.919 --> 00:14:52.000 on some of our larger capacity especially if 00:14:52.000 --> 00:14:54.179 we get into like that m3 status where we have 00:14:54.179 --> 00:14:57.539 high refrigerant charge and we may require additional 00:14:57.539 --> 00:15:00.299 strategies like maybe a pump down mode using 00:15:00.299 --> 00:15:03.700 an additional solenoid are those types of controls 00:15:03.700 --> 00:15:09.039 part of the modular yes so again most of those 00:15:09.039 --> 00:15:11.399 schemes that you talked about yeah whether it 00:15:11.399 --> 00:15:15.100 be isolation valves or a pump down you're going 00:15:15.100 --> 00:15:18.279 to control through relay no kidding so you have 00:15:18.279 --> 00:15:22.720 the ability to control your relays in the normal 00:15:22.720 --> 00:15:27.539 mode you decide okay when the temperature isn't 00:15:27.539 --> 00:15:32.120 satisfied do i want my compressor on or compressor 00:15:32.120 --> 00:15:35.159 off in normal mode. And then when it goes into 00:15:35.159 --> 00:15:38.259 mitigation, what do I want the status of those 00:15:38.259 --> 00:15:41.419 to be? And what's important with that is it gives 00:15:41.419 --> 00:15:45.059 you the flexibility, for instance, with an isolation 00:15:45.059 --> 00:15:50.360 valve, right? It'll probably be a normally open 00:15:50.360 --> 00:15:54.659 set of contacts. Well, whether you lose power 00:15:54.659 --> 00:15:59.070 or whether you go into mitigation. You want those 00:15:59.070 --> 00:16:02.289 isolation belts to be closed. So you have to 00:16:02.289 --> 00:16:05.289 have the way to configure it so that they're 00:16:05.289 --> 00:16:07.750 in the proper state when you go into mitigation 00:16:07.750 --> 00:16:10.029 and when the power is off. Makes complete sense. 00:16:10.490 --> 00:16:13.149 So there's a lot of flexibility here. And you 00:16:13.149 --> 00:16:15.549 do that, again, by adding the expansion modules. 00:16:15.870 --> 00:16:18.110 Yeah. I'm really liking this idea because you 00:16:18.110 --> 00:16:21.409 can start with however minimal of a strategy 00:16:21.409 --> 00:16:24.610 you need. up to whatever capability of strategy 00:16:24.610 --> 00:16:27.009 you need simply by adding the modules and changing 00:16:27.009 --> 00:16:29.269 the programming. I mean, we're manufacturers 00:16:29.269 --> 00:16:32.629 and contractors if they want, you know, to look 00:16:32.629 --> 00:16:35.009 at kind of a field engineering solution. Yeah. 00:16:35.330 --> 00:16:37.629 Where they get the most out of a controller like 00:16:37.629 --> 00:16:39.769 this is use the full functionality. I see that. 00:16:39.909 --> 00:16:42.370 So that's where, you know, a combination of temperature 00:16:42.370 --> 00:16:45.470 control or temperature and humidity control or 00:16:45.470 --> 00:16:47.889 temperature, humidity, and pressure control with 00:16:47.889 --> 00:16:50.210 the A2L leak detection and mitigation. You know, 00:16:50.230 --> 00:16:53.259 I guess I... almost skipped past that so we're 00:16:53.259 --> 00:16:56.539 not talking about just a a2l detection and mitigation 00:16:56.539 --> 00:16:58.480 we're talking about a full system controller 00:16:58.480 --> 00:17:02.320 correct correct with a2l detection and mitigation 00:17:02.320 --> 00:17:06.819 yeah and then like i said before but modular 00:17:06.819 --> 00:17:09.980 chillers modular boilers yeah or it could be 00:17:09.980 --> 00:17:13.599 single stage chiller single stage boiler um you 00:17:13.599 --> 00:17:15.740 know all of your refrigeration applications so 00:17:15.740 --> 00:17:18.619 we have all the defrost modes incorporated in 00:17:18.619 --> 00:17:22.480 here oh wow off -cycle defrost electric defrost, 00:17:22.680 --> 00:17:28.220 hot gas bypass, and adaptive defrost. So adaptive 00:17:28.220 --> 00:17:33.700 is where it actually learns and optimizes the 00:17:33.700 --> 00:17:35.500 defrost cycle. Yep, absolutely. We're seeing 00:17:35.500 --> 00:17:37.640 that a lot as we move forward because we can 00:17:37.640 --> 00:17:40.539 now manage those defrost cycles using some temperature 00:17:40.539 --> 00:17:43.980 thermistors and occasionally a transducer. We 00:17:43.980 --> 00:17:47.980 can monitor the actual coil temperatures. It's 00:17:47.980 --> 00:17:50.390 absolutely necessary. yeah you know if we think 00:17:50.390 --> 00:17:52.490 about if we got an ambient temperature that is 00:17:52.490 --> 00:17:54.470 you know 40 degrees why do i go into defrost 00:17:54.470 --> 00:17:56.509 i've already got some heat out there that i can 00:17:56.509 --> 00:18:00.069 utilize if i'm managing my defrost properly and 00:18:00.069 --> 00:18:01.910 then i can control the lengths of those cycles 00:18:01.910 --> 00:18:05.769 there's a lot of flexibility in in managing defrost 00:18:05.769 --> 00:18:07.490 and we're going to be able to we're going to 00:18:07.490 --> 00:18:09.549 handle a lot of capability then with the single 00:18:09.549 --> 00:18:13.809 modular control yeah let's see if we're in uh 00:18:13.809 --> 00:18:18.599 if we're in countdown or not Looks like we're 00:18:18.599 --> 00:18:25.119 still in countdown. So we won't let it. Oh, OK. 00:18:25.200 --> 00:18:28.079 We finished countdown now. And now you can see 00:18:28.079 --> 00:18:32.599 the screen is saying confirm that now we can 00:18:32.599 --> 00:18:34.940 go back into normal mode. And that's, you know, 00:18:34.940 --> 00:18:41.940 again, because we're connected via Modbus, we 00:18:41.940 --> 00:18:47.259 can tell why did the. controller alert why did 00:18:47.259 --> 00:18:50.660 it alarm we can tell the difference between a 00:18:50.660 --> 00:18:54.640 refrigerant leak and a sensor failure or a sensor 00:18:54.640 --> 00:18:56.619 that went end of life and that's one thing i'm 00:18:56.619 --> 00:18:58.799 going to talk about now okay because we can see 00:18:58.799 --> 00:19:02.279 the lfl level yeah in addition to the features 00:19:02.279 --> 00:19:05.339 that i talked about there's also a 0 to 10 volt 00:19:05.339 --> 00:19:10.420 output that you can again tie into a supervisory 00:19:10.420 --> 00:19:13.869 controller and it will tell you the highest LFL 00:19:13.869 --> 00:19:16.369 value of any sensor connected to the controller. 00:19:16.490 --> 00:19:20.329 Okay. So in this case we know, because we saw 00:19:20.329 --> 00:19:24.349 the 25 % LFL, but specifically as Bill talked 00:19:24.349 --> 00:19:27.089 about earlier, you have the ability to name your 00:19:27.089 --> 00:19:30.710 sensors, so you can actually tell, okay, it was 00:19:30.710 --> 00:19:34.630 the number one sensor that's located on the left 00:19:34.630 --> 00:19:37.509 -hand side of the evaporator coil, and I know 00:19:37.509 --> 00:19:40.109 that's the one. that i need to pay attention 00:19:40.109 --> 00:19:43.349 to on the leak side oh now that's really adding 00:19:43.349 --> 00:19:46.450 some features to it you know if we think about 00:19:46.450 --> 00:19:49.089 a system that has multiple sensors and we're 00:19:49.089 --> 00:19:52.869 tracking that lfl and now we can actually track 00:19:52.869 --> 00:19:55.369 and graph we can monitor you know what if i have 00:19:55.369 --> 00:20:00.210 a sensor picking up a small amount of refrigerant 00:20:00.210 --> 00:20:03.549 leak at a particular time every day now i can 00:20:03.549 --> 00:20:06.210 go back and look at my trends and go oh that's 00:20:06.210 --> 00:20:08.990 when we went into hot gas defrost I better start 00:20:08.990 --> 00:20:11.529 looking for a leak on that loop. Yeah, that's 00:20:11.529 --> 00:20:16.829 a good, that is a very good point. So again, 00:20:16.950 --> 00:20:20.349 this is an intelligent system. It's full featured. 00:20:20.549 --> 00:20:24.650 It gives you the ability to expand your outputs 00:20:24.650 --> 00:20:28.869 on either adding relays or adding analog output. 00:20:30.089 --> 00:20:33.549 So very, very flexible in terms of control types. 00:20:34.279 --> 00:20:35.740 Will this be hitting the market pretty soon? 00:20:35.859 --> 00:20:38.980 It was released last October. Really? Wow. Yeah, 00:20:39.000 --> 00:20:41.039 it was released last October. We've been working 00:20:41.039 --> 00:20:46.200 with OEMs. So you know the first compliance date 00:20:46.200 --> 00:20:50.240 was January 1 of this year for AC equipment. 00:20:50.519 --> 00:20:54.519 So most of the AC manufacturers that are using 00:20:54.519 --> 00:20:58.680 this, they've already complied with UL or ETL 00:20:58.680 --> 00:21:02.109 or some other agency. And now we're continuing 00:21:02.109 --> 00:21:04.609 to work with commercial refrigeration manufacturers 00:21:04.609 --> 00:21:09.490 that, again, see the benefit of having a control 00:21:09.490 --> 00:21:13.589 that can do not only A2L leak detection and mitigation, 00:21:14.269 --> 00:21:17.190 but also some of the other functions that they're 00:21:17.190 --> 00:21:19.910 using the controller for today. you bet well 00:21:19.910 --> 00:21:22.390 you look at a you know refrigeration manufacturer 00:21:22.390 --> 00:21:25.470 you know if i am a component manufacturer and 00:21:25.470 --> 00:21:28.230 i'm going to be producing a say an evaporator 00:21:28.230 --> 00:21:30.369 coil and i don't know what refrigerant that is 00:21:30.369 --> 00:21:32.910 going to be installed on i now have one controller 00:21:32.910 --> 00:21:35.789 if i'm in an a1 refrigerant i just need my primary 00:21:35.789 --> 00:21:38.130 controller if i'm going to be going on to an 00:21:38.130 --> 00:21:40.750 a2l system i'm just adding a module and now i'm 00:21:40.750 --> 00:21:43.150 completely in compliance with that same base 00:21:43.150 --> 00:21:47.079 control you don't have to use a2l leak detection 00:21:47.079 --> 00:21:50.779 and mitigation yeah you can when it comes from 00:21:50.779 --> 00:21:53.960 the factory it's disabled yeah if you want to 00:21:53.960 --> 00:21:57.279 use it you enable it i think a lot of the customers 00:21:57.279 --> 00:22:00.500 we talked to keep too right a year and a half 00:22:00.500 --> 00:22:03.420 ago it was oh i've got to have a new controller 00:22:03.420 --> 00:22:06.980 designed or i've got to go back and have my 5 00:22:06.980 --> 00:22:11.940 000 controller capable of accepting sensors and 00:22:11.940 --> 00:22:16.700 you know we're coming in with a simple but very 00:22:16.700 --> 00:22:21.319 high value option for them and it's been amazing 00:22:21.319 --> 00:22:24.980 how many of them have said yours is plug and 00:22:24.980 --> 00:22:29.420 play for me oh yeah i don't have to redo my full 00:22:29.420 --> 00:22:32.500 controller for the building and everything else 00:22:32.500 --> 00:22:36.579 it fits right in and it's a cost -effective option 00:22:36.579 --> 00:22:39.420 to what we have now you're almost starting to 00:22:39.420 --> 00:22:42.900 get into the sensor side when you you're starting 00:22:42.900 --> 00:22:47.200 to talk about that Keith kind of leads into yeah 00:22:47.200 --> 00:22:51.000 just technology but what's continuing to evolve 00:22:51.000 --> 00:22:53.380 yeah it's an evolving landscape yeah so this 00:22:53.380 --> 00:22:58.440 particular sensor uses sound technology yeah 00:22:58.440 --> 00:23:03.140 so it's the fastest sensor out there sound technology 00:23:03.140 --> 00:23:07.180 is relatively new to leak detection but we've 00:23:07.180 --> 00:23:12.069 had several now of our customers actually do 00:23:12.069 --> 00:23:16.029 specific testing to make sure the sensor was 00:23:16.029 --> 00:23:19.549 picking up the right concentration and all of 00:23:19.549 --> 00:23:21.730 them the results have shown that that they're 00:23:21.730 --> 00:23:24.990 within spec certainly within spec so speed of 00:23:24.990 --> 00:23:28.130 sound there's simply put there's two stainless 00:23:28.130 --> 00:23:31.150 steel debt discs behind this hydrophobic screen 00:23:31.150 --> 00:23:34.329 this hydrophobic screen allows gases to pass 00:23:34.329 --> 00:23:38.430 through but sheds liquids so as that refrigerant 00:23:38.430 --> 00:23:41.869 leaks and that gas then pools inside the sensor 00:23:41.869 --> 00:23:46.690 cavity then it's going to measure not only the 00:23:46.690 --> 00:23:49.569 sound wave it's going to measure that because 00:23:49.569 --> 00:23:53.609 part of the ul60335 is that it's self -monitored 00:23:53.609 --> 00:23:56.849 right so every minute it checks its calibration 00:23:56.849 --> 00:24:00.650 against a temperature and humidity baseline why 00:24:00.650 --> 00:24:04.400 because speed of sound changes based on temperature 00:24:04.400 --> 00:24:07.140 and humidity right right so it's got a temperature 00:24:07.140 --> 00:24:14.019 and humidity sensor yeah not only that but it 00:24:14.019 --> 00:24:18.519 has a countdown so the life is 15 years right 00:24:18.519 --> 00:24:21.559 because it's communicating through modbus it 00:24:21.559 --> 00:24:25.660 is counting down how many days are left on the 00:24:25.660 --> 00:24:29.000 sensor when it gets to 90 days from the end of 00:24:29.000 --> 00:24:33.319 life if you just have the controller here is 00:24:33.319 --> 00:24:35.460 going to give you a badge or an alert saying 00:24:35.460 --> 00:24:37.480 you need change you're approaching this point 00:24:37.480 --> 00:24:41.799 right and then if you're connected to the cloud 00:24:41.799 --> 00:24:44.799 you're going to get start getting alerts on your 00:24:44.799 --> 00:24:48.759 smart device so you know at some point if you 00:24:48.759 --> 00:24:51.039 don't change the sensor out it's going to go 00:24:51.039 --> 00:24:53.140 end of life right and your system's going to 00:24:53.140 --> 00:24:56.680 be down so that's another point of smart smart 00:24:56.680 --> 00:25:00.519 is not only is it functioning correctly is it 00:25:01.109 --> 00:25:03.750 within its lifespan. And that's been a big concern 00:25:03.750 --> 00:25:06.049 of technicians. You know, what is the life expectancy? 00:25:06.289 --> 00:25:07.789 How often do I need to replace these? There's 00:25:07.789 --> 00:25:10.509 been a lot of miscommunication amongst technicians 00:25:10.509 --> 00:25:13.170 not understanding that these have a life expectancy 00:25:13.170 --> 00:25:15.230 that's typically in the range of the equipment 00:25:15.230 --> 00:25:18.549 and understanding that some of our better sensors, 00:25:18.609 --> 00:25:20.630 I know this one very well, I've been studying 00:25:20.630 --> 00:25:22.450 the different types of technology we're using 00:25:22.450 --> 00:25:25.410 and it really has been a very accurate sensor 00:25:25.410 --> 00:25:29.759 and the whole communication component. Where 00:25:29.759 --> 00:25:32.440 the sensor actually knows its life and can give 00:25:32.440 --> 00:25:34.519 us those alarms really simplifies the whole maintenance 00:25:34.519 --> 00:25:36.460 side. How do you make the contractor's life easier? 00:25:36.460 --> 00:25:38.960 That's it. Right? I mean, everybody's got so 00:25:38.960 --> 00:25:42.200 much going on. The more information we can share 00:25:42.200 --> 00:25:45.779 with them, the smarter they are when they go 00:25:45.779 --> 00:25:48.460 out on the job site. Yeah. Now, the other sensor 00:25:48.460 --> 00:25:50.960 that's been out there for a while, not only for 00:25:50.960 --> 00:25:55.259 A2L, but for... just a general thing is ndir 00:25:55.259 --> 00:25:59.539 non -dispersive infrared it's it's reliable it's 00:25:59.539 --> 00:26:02.839 just not as fast as speed of sound yep and when 00:26:02.839 --> 00:26:05.480 you're talking about refrigerant leaks you know 00:26:05.480 --> 00:26:08.799 you want something that's not only reliable but 00:26:08.799 --> 00:26:14.029 extremely fast i've seen a lot of our um even 00:26:14.029 --> 00:26:16.509 our portable refrigerant leak detection devices 00:26:16.509 --> 00:26:18.529 go into this technology. And I mean, it's really 00:26:18.529 --> 00:26:20.009 smart when we think about it. You know, some 00:26:20.009 --> 00:26:22.490 of our, many of our previous sensors, you know, 00:26:22.490 --> 00:26:24.710 had heated components to them. And whether they 00:26:24.710 --> 00:26:26.730 reached a high temperature threshold or not, 00:26:26.809 --> 00:26:29.049 they were heated components. And as we start 00:26:29.049 --> 00:26:31.670 looking at sensors that are detecting potentially 00:26:31.670 --> 00:26:36.710 mildly flammable gases using a technology that 00:26:36.710 --> 00:26:40.490 is low temperature as well as, you know, a lower 00:26:40.490 --> 00:26:43.259 amount of current. uh this makes for a smarter 00:26:43.259 --> 00:26:45.819 uh decision going forward i think personally 00:26:45.819 --> 00:26:50.140 okay we want to talk about the next step in the 00:26:50.140 --> 00:26:52.819 industries on sensors we're working on right 00:26:52.819 --> 00:26:56.920 everybody came out one refrigerant one sensor 00:26:56.920 --> 00:27:00.099 the way it works now we're along with a number 00:27:00.099 --> 00:27:03.319 of companies are working on a sensor for multiple 00:27:03.319 --> 00:27:08.000 refrigerators oh good yeah so yeah 454 a b or 00:27:08.000 --> 00:27:15.019 c right 455a on one air conditioning and heating 00:27:15.019 --> 00:27:21.359 454b r32 think of the changes for the contractor 00:27:21.359 --> 00:27:25.039 on the truck for the wholesaler on inventory 00:27:25.039 --> 00:27:28.859 it just makes again how do we make people's life 00:27:28.859 --> 00:27:32.440 much easier as they get to the job site yeah 00:27:32.440 --> 00:27:35.819 so two things here one that i'll point out a 00:27:35.819 --> 00:27:39.369 lot of these sensors look alike But this one 00:27:39.369 --> 00:27:42.109 actually is powered by 24 volts. Constant then. 00:27:42.269 --> 00:27:45.349 And it's a Modbus sensor. Yeah. It's fully communicating. 00:27:45.349 --> 00:27:49.529 So it will only work with System 550. It requires 00:27:49.529 --> 00:27:54.130 a 24 -volt sensor. Supply. And it requires a 00:27:54.130 --> 00:27:57.109 Modbus communicating sensor. Nice. There are 00:27:57.109 --> 00:27:59.970 sensors that are out there that are a combination 00:27:59.970 --> 00:28:04.049 of Modbus and relay outputs. But the ones that 00:28:04.049 --> 00:28:07.480 use relay outputs, they work fine. but they don't 00:28:07.480 --> 00:28:09.180 have all the smarts that we're talking about 00:28:09.180 --> 00:28:10.819 here and i worry about those having excessive 00:28:10.819 --> 00:28:13.980 load uh you know i like a sensor to be a sensor 00:28:13.980 --> 00:28:18.359 yeah so the other thing bill talked about just 00:28:18.359 --> 00:28:22.059 to kind of tee off of that is yes i mean now 00:28:22.059 --> 00:28:26.279 we've got five different sensors one that's calibrated 00:28:26.279 --> 00:28:29.460 for each a2l refrigerant two on the hpc side 00:28:29.460 --> 00:28:32.559 three on the commercial refrigeration side right 00:28:32.559 --> 00:28:35.200 in the future what you'll find is there'll be 00:28:35.200 --> 00:28:39.750 a dual refrigerant on the HVAC side. So we'll 00:28:39.750 --> 00:28:43.549 have to take some compromises in terms of what 00:28:43.549 --> 00:28:47.569 the LFL level and what the trip point is. So 00:28:47.569 --> 00:28:51.750 on the HVAC side, you'll see one sensor for R32 00:28:51.750 --> 00:28:56.230 and R454B. But again, you will have probably 00:28:56.230 --> 00:29:01.369 a lower LFL trip point because those two refrigerants 00:29:01.880 --> 00:29:04.420 their properties are much different. And the 00:29:04.420 --> 00:29:07.319 refrigeration side of things. So you take worst 00:29:07.319 --> 00:29:11.059 case and go with that for your base. Yeah. And 00:29:11.059 --> 00:29:12.960 on the commercial refrigeration side, there'll 00:29:12.960 --> 00:29:15.579 be, as Bill said, there'll be three refrigerants 00:29:15.579 --> 00:29:22.240 starting with R454A, then R454C, and then R455A. 00:29:22.839 --> 00:29:27.519 So again, we will calibrate to what we call a 00:29:27.519 --> 00:29:31.710 lead refrigerant and that will set the LFL. trip 00:29:31.710 --> 00:29:35.829 point makes sense yeah interesting discussions 00:29:35.829 --> 00:29:40.269 too with propane and i've spent a lot of time 00:29:40.269 --> 00:29:43.069 talking to customers who are saying hey we'd 00:29:43.069 --> 00:29:46.630 like this type of setup if if our industry in 00:29:46.630 --> 00:29:49.890 north america decides we're going to go with 00:29:49.890 --> 00:29:53.029 bigger charges yeah than the 500 grams we have 00:29:53.029 --> 00:29:55.809 today right on self -contained they're doing 00:29:55.809 --> 00:29:59.099 that in other parts of the world can you bring 00:29:59.099 --> 00:30:02.640 this kind of capability for propane? It's perfect 00:30:02.640 --> 00:30:05.200 for that. Yeah. What we're saying is as the industry 00:30:05.200 --> 00:30:09.500 evolves, right, not just propane but other refrigerants, 00:30:09.500 --> 00:30:13.000 then those are opportunities we'll take advantage 00:30:13.000 --> 00:30:17.119 of to have a solution for the customers out there. 00:30:17.339 --> 00:30:21.880 Yeah, absolutely. I mean, the same sensors because 00:30:21.880 --> 00:30:26.650 it's really the technology. can be used for r290 00:30:26.650 --> 00:30:29.029 reprogrammed for different lfls they can be used 00:30:29.029 --> 00:30:31.849 for co2 as well yeah for sure and that's the 00:30:31.849 --> 00:30:34.329 thing is you know having this flexibility of 00:30:34.329 --> 00:30:37.190 you know being prepared for whatever is next 00:30:37.190 --> 00:30:39.630 um you know our our president you know howard 00:30:39.630 --> 00:30:41.910 weiss he always says we don't know what the next 00:30:41.910 --> 00:30:45.089 refrigerant is it might be milk if it is we're 00:30:45.089 --> 00:30:47.269 just going to educate an industry on how to work 00:30:47.269 --> 00:30:51.069 with milk and having a modular design gives us 00:30:51.069 --> 00:30:54.250 that flexibility of whatever comes next we have 00:30:54.759 --> 00:30:57.240 Minimal transition for that technician. And you're 00:30:57.240 --> 00:30:59.839 right. What's the easy button for them? Is it 00:30:59.839 --> 00:31:01.680 a matter of replacing a sensor and doing a little 00:31:01.680 --> 00:31:03.660 programming as we make a refrigerant change? 00:31:04.099 --> 00:31:06.619 Sounds like a pretty easy solution to me. I mean, 00:31:06.640 --> 00:31:08.640 we all would like some stability for the next 00:31:08.640 --> 00:31:12.740 few years as we get everybody trained up in understanding 00:31:12.740 --> 00:31:15.599 the application. So hopefully we're not going 00:31:15.599 --> 00:31:19.400 to have too many changes in the foreseeable future 00:31:19.400 --> 00:31:21.819 here. Sure. Yeah, this will get us through that. 00:31:22.279 --> 00:31:25.420 in that process all right and so are these available 00:31:25.420 --> 00:31:27.859 directly from johnson controls or the local distributor 00:31:27.859 --> 00:31:32.859 what is the process so um we have actually introduced 00:31:32.859 --> 00:31:37.599 we've discontinued one of the families that started 00:31:37.599 --> 00:31:42.259 the modular control system system 350 and so 00:31:42.259 --> 00:31:45.599 we we actually have another version of system 00:31:45.599 --> 00:31:50.380 550 that has one sensor input Doesn't have A2L 00:31:50.380 --> 00:31:53.940 leak detection mitigation. Okay. And we've completed 00:31:53.940 --> 00:31:57.339 the firmware for that product. That is now available 00:31:57.339 --> 00:31:59.900 for purchase. We're in production now, and that's 00:31:59.900 --> 00:32:04.039 called our C550A control modules. Okay. So what 00:32:04.039 --> 00:32:08.500 you see here is a C550C. Yep. The A's are kind 00:32:08.500 --> 00:32:10.599 of more simplistic controls. Standalone. System 00:32:10.599 --> 00:32:15.140 350, or to replace the old analog controls. What's 00:32:15.140 --> 00:32:18.519 unique about them is that... They have a guided 00:32:18.519 --> 00:32:22.599 setup. Oh, OK. So similar to you replacing like 00:32:22.599 --> 00:32:25.160 a spark plug in your car where you go in and 00:32:25.160 --> 00:32:27.940 say, OK, I've got this make and model. Here's 00:32:27.940 --> 00:32:30.339 my cross reference. You just basically go into 00:32:30.339 --> 00:32:34.220 the dial. You dial what your previous was replacing 00:32:34.220 --> 00:32:36.880 and it will walk you through everything you need 00:32:36.880 --> 00:32:39.579 to do to configure that device.
