对于普通热泵来说,随着房间空调器领域R410A替代R22的大规模市场化应用,越来越多的热泵企业推出R410A的热泵热水产品,但是R410A的GWP接近2000,需要考虑合适的替换冷媒。热泵热水器的运行模式为全年高水温运行,R32在同等情况下排气温度要高出R410A 15℃以上,...
This paper presents an experimental evaluation of two low GWP refrigerants candidates for the replacement of R-410A in an "air to water" heat pump. The baseline is evaluated following the ANSI/AHRI Standard 551/591. For both low GWP candidates (ARM-70a and DR-5), tests are performed follo...
Abstract: With the increasing attention of the world to environmental problems, R22 refrigerant products in heat pump industry have been gradually reduced in use, and mainstream refrigerants such as R134a and R410A have been included in the scope of controlled substances. The use of lower GWP re...

OneHCFO refrigerant(hydrochlorofluorocarbons) has very low GWP values as well; this is the newR-1233zdwith 1 GWP. Many HO (hydroolefins) refrigerants have exceptionally low GWP values. Examples include R-432A with 1.64 GWP, R-1270 (propane) with 1.8 GWP, R-433A with 2.85 GWP, R-433C...
R-32 is a next generation refrigerant that efficiently carries heat and has lower environmental impact. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units. Although there are various types of refrigerants, R-32...
