Member Meeting

May 5 @ 11:00 am - 12:30 pm

May 5th – Meeting MarHY – 3850 SE International Way, Milwaukie, OR 97222
This will be a Hybrid meeting. In person and zoom. 

Since this is the first of our in person/hybrid meetings, attendees will be treated to lunch, compliments of MarHy, while those on zoom will have to settle for drive thru.

Join us on May 5th, at 11:00AM at Marhy Distributing, for a presentation by Len Crawford, who will briefly overview Daikin’s new Atmosphera R-32 ductless product and then have generic discussion of A2L and low GWP refrigerants for the upcoming federal requirements.

Say Farewell to R-410A Refrigerants

Are you prepared for the transition to different refrigerants being used in new production units entering the US market? The HVAC industry is changing refrigerants in new products once again.

Say goodbye to R-410A and hello to R-32 and R-454B. What are these new refrigerants? Professional HVAC tradespeople need to stay on top of the new and innovative technology as it enters our market. Take the opportunity now to invest in your career and prepare yourself for the next wave of new refrigerants. Join us on May 5, 2022 at MarHy Distributing, at 11:00AM, or dial into our meeting via zoom.

Since the HFC (R-410A) phasedown has begun, the HVACR industry will transition from equipment using R-
410A to Low GWP (R-32 and R-454B) Refrigerants, so Be Prepared! To help you prepare others to safely
handle, store, and transport these Low Global Warming Potential but mildly flammable refrigerants.
The ORACCA May 5th A2L Refrigerant training, presented by Len Crawford, Regional Sales Director for
Daikin, Amana, and Goodman products is designed to help HVAC professionals prevent ignition while working
with A2L refrigerants and educate staff on the best safety practices to keep employees and clients safe. The A2L
refrigerant training has a few specific targets in mind.

Why switch from R-410A? Why now?
We need refrigerants with a low global warming potential. Each refrigerant has a Global Warming Potential (GWP) with carbon used as the base. Carbon has a GWP of 1. R410A has a GWP of 2,088 meaning that if one kilogram is released into the atmosphere it would have 2,088 times the harmful effect of one kilogram of carbon. That is why we are now seeing a move to a new refrigerant – R32, which has a GWP of 675 (two-thirds less than R410a) and R-454B with a GWP rating of 466. The decision by air conditioner manufacturers to transition to a new refrigerant is driven by many factors such as impact on the environment, energy efficiency, safety and cost-effectiveness. For instance, the working (operating) pressure of R32 is about 12 – 26 Bar (174-377 Psi). It should be noted that while the operating pressure of R32 and R410A is similar, the former has a better ability to exchange heat-load, thus delivering a higher capacity. R-410A (A1) R-32 R.
