Refrigerant choice in HVAC chillers
December 06, 2021
In the light of the worldwide phase-down of high GWP refrigerants, Dave Richards, UK head of sales at refrigerant supplier Climalife, looks at the various options available for HVAC chillers.
There are many different types of chiller, however in terms of refrigerant they can be split into three types: low, medium and high pressure.
While legislation is driving and influencing the choice of refrigerant, from a European perspective the F-gas legislation has not implemented any bans for chiller applications as they have not used refrigerant with a GWP >2500. However, the European F-gas phase down and similar reductions under the global Kigali Amendment will have a profound effect on the choice of refrigerant used in new chillers in the next few years.
