We’ve reached summer, and it’s time for another HVAC/Roundup; a look at the topics we found important over the last few weeks - and keep reading to the end for a special announcement:
We enjoy exploring the complexities of HVAC, refrigerant management, legislation, and climate action, but on occasion more basic questions cross our desk. So here is a bit of HVAC/R 101.
Did you know that when a technician takes refrigerant from your site to be disposed of, it’s your responsibility both in terms of compliance and stewardship to know where it’s going? Last month we discussed refrigerant recycling vs destruction of ozone depleting CFCs with the conclusion that between the two, destruction is the better option from both an economic and environmentally-sound standpoint.
A Refrigerant Reference Guide
Refrigerants come in all shapes and sizes. Thirty years ago, there were 2 types of refrigerants: low pressure and high pressure. For high pressure there were 3 flavors: R-12 (medium temp refrigeration), R-502 (low temp refrigeration) and R-22 (everything else).
These refrigerants seemed easy, they were cheap, and every supply house had all 3 flavors. In the back of every service truck there were 3 bottles of refrigerant (green, purple & white) along with a vacuum pump, acetylene torch, tools and something to help move heavy compressors around. Most service events were referred to as “Gas & Go” and involved very little or no leak checking. But then it became apparent that this less than scientific method to fixing things needed to change - because there was a hole in the ozone.
Believe it or not, we're getting close to the end of the month. We had a lot to talk about the last few weeks. Let's sum things up...
Together we lose $27 billion dollars (US) - if you own or manage a building, your share is $6,750/year
We regularly share information about how to better manage refrigerants, we talk about their impact, results from our work, and stories we hear from others. This week we’re reviewing a report by the EIA (Environmental Investigation Agency). Yes they are a European environmental group, and their goal of spreading climate change awareness may seem out of touch with the day to day responsibilities of the average building owner/manager in the US. But if you replace the word climate change with lost profit, this story has some revealing results.
