Summary

Chris LaPietra, vice president and general manager of Honeywell Stationary Refrigerants, joins us to talk about some new releases from Honeywell. He also covers refrigerants in general.

As our industry reduces its reliance on R-22 (and eventually R-410A), we have turned to more flammable solutions. There is a tradeoff in safety for the lower GWP, though. However, along with some slightly less flammable A2L refrigerants, Honeywell is releasing two new A1 refrigerants: R-466A and R-515B (N-15). These are non-toxic, don't catch fire, and have a lower environmental impact than R-410A and R-22.

The Montreal Protocol was a groundbreaking initiative to phase out ozone-depleting substances to help slow down climate change. As a result, R-22 has undergone a phase-out. The Kigali Amendment is the next step, which addresses global warming potential and targets substances with high GWP for a phase-down. So, as R-410A will go in a similar direction to R-22, manufacturers have come on the scene; they are developing alternative refrigerants that address the global climate initiative. Instead of creating new HFCs, manufacturers are inventing new blends and HFOs to replace HFCs.

Honeywell wants to avoid creating undue risk in the marketplace. So, they take feedback from their customers and make sure technicians feel comfortable working with their refrigerants. They also keep the best practices pretty similar to those of working with R-410A.

Chris and Bryan also discuss:

Residential HVAC vs. commercial refrigeration solutions
The ZE product line
ASHRAE terms and definitions
How R-32 is made (and A2L refrigerant blends)
Global warming potential (GWP) vs. ozone-depleting potential (ODP)
How Honeywell develops new refrigerants
Trading off efficiency for lower GWP
E-cooling and the potential of the electronics market

0:00.0	So this is one of many podcasts recorded live from AHR Expo 2020 here in Orlando.
0:09.9	My hometown, HR was nice enough to allow us to record and to set up some great equipment for us.
0:16.3	So big thanks to AHR for doing this.
0:18.4	It's been a great event.
0:20.1	Thank you to all of our sponsors, Field Piece, Carrier, Navac, Refrigeration Technologies,
0:25.9	and Speed Clean for making this podcast and all of our podcast possible.
0:30.4	But most of all, thank you to everybody who participated in these episodes and who came up and said so many nice things about what we're doing at HVAC school.
0:38.2	Hope you enjoy.
0:49.5	And And now the man who tries to explain makeup air and ventilation to his kids whenever they eat out. Brian Orr.
0:53.7	This episode of the HVAC School podcast is special because we actually got a chance to talk to one of the
0:58.8	executives with Honeywell Refrigerants, Chris Lapetra, and they had several announcements at the show from interesting new
1:06.0	refrigerants and rather than just talking only about the new refrigerants
1:09.7	that they have we just sort of had a broad conversation about the changing landscape as it
1:13.4	relates to refrigerants. A lot of us who are in the residential side of things
1:17.0	primarily don't necessarily think of some of the other segments of the
1:20.4	industry and some of the other refrigerants that are being phased out or
1:24.3	are going to be changed over the next little bit and so we have a conversation
1:27.0	about that. So this is Chris Lapetra with Honeywell Refrigerance. Hope you enjoy.
1:33.0	All right, so I am here with Chris Lapetra from Honeywell Refrigerance. Is that the...
1:39.0	Honeywell Refrigerance?
1:40.0	Honeywell Refrigerance. Okay. So, honor to be here. It's always fun to talk to industry leaders and Honeywell has some pretty cool releases at the show. We're here at AHR 2020 in Orlando. So let's start with the new refrigerant release because I think
1:55.9	that's probably what people are most interested in and sure there's been so much
	...
