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:
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.
