Ozone-depleting substances (ODS) have been regulated as class I or class II controlled substances by the US Environmental Protection Agency. Class I substances, which have higher ozone depletion potential, have been completely phased out in the U.S., with a few exceptions. Class II substances are all transitional substitutes for many class I substances, and are all hydrochlorofluorocarbons (HCFCs). By 2020, new production and imports of HCFCs will be phased out completely. The most common HFCF today is referred to as R-22, a refrigerant still used in existing HVAC units.
The truth is that the R-22 phase-out should scare people. The risk is very real, but people seem to be avoiding the problem signs. If you’re a contractor with an existing HVAC unit, you need to take action. Pay close attention to the details, and the planning process will be painless for you.
Some distributors may not be able to sell large quantities of chiller conversions to a contractor. Ensure that you’re prepared and contact likely vendors to see what’s available, when you can receive your order and how.
Understand the Best Refrigerant Choice for the Future
Your choice of refrigerant will probably affect your system’s capacity, temperature glide and operating pressures, among other variables. It may be necessary for you to alter expansion devices and adjust control settings. Research refrigerant manufacturers, system manufacturers, and ASHRAE to gain as much knowledge as you can.
Allow for Enough Time
3 opinions are always better than 1. Get multiple views on your choices and on the timelines. Understand that fully cleaning and evacuating a system of refrigerants takes a considerable amount of time. This is going to be a continuous, repetitive cycle that requires patience and perseverance. Plan for a two-week period of conversions, and schedule the necessary resources.
For distributors and contractors, the most important way to cope with the R-22 phase-out is to stay informed. Those who are well informed are in a better position of helping their customers and themselves. Take advantage of education tools provided on the subject!
