WHITE PAPER 4.2 Air conditioning Development for air conditioning in advanced markets has been similar, with previous users of R410A choos- ing R32 or similar refrigerant options. In applications involving R134a (1,1,1,2-Tetrafluoroethane), however, the trend has been toward HFO blends, such as R1234ze refrigeration and air conditioning systems. (1,3,3,3-Tetrafluoropropene). The most used natural refrigerant is ammonia for bigger central air conditioning and hydrocarbons for small residential applications. CO2 is increasingly used in supermarkets, combining the Air Conditioning Alternative refrigerants Substance GWP Composition Replacement for R717 (ammonia) 0 – R134a R407A R410A Natural refrigerants Synthetic HFOs 4.3 Refrigeration R290 (propane) R744 (CO2) R1234zd R1234ze 3 – 1 – 4,5 – 7 – R134a R407A R410A R134a R407A R410A R134a R410A R134a Synthetic HFC-HFO blends R452B R454B R455B R513B 698 466 148 631 R32/125/1234yf R32/1234yf R321234yf/CO2 R1234yf/134a R410A R410A R404A R134a Synthetic HFCs R32 675 – R134a R407A R410A Instead of the high-GWP R404A, some businesses have begun employing synthetical lower HFC-HFO blends, such as R448A and R449A. In contrast to the air condi- tioning and heat pump markets, however, the growing trend in refrigeration has been in favour of natural refrigerants. The development of technologies to further increase energy efficiency while using natural refrigerants will spur this trend going forward.
