Abstract
CO2 is a HCFCs substitution in HPMP of industrial and commercial refrigeration ( ICR) sector in China. In this paper, the ap⁃plicability of natural refrigerant CO2 application in ICR is analyzed by standards, testing, replacement cost and market prospect. The con⁃clusion indicates that:1) based on the leaking and suffocation risk charging limit, CO2 can be used in all refrigeration systems theoretical⁃ly in relevant standards;2) under ultra⁃low temperature condition and nominal condition in GB/T 21362—2008, the COP of CO2 heat pump water heater is 7. 9% and 10. 7% higher than R410A unit, and the performance of CO2 air⁃cooler evaporator is better than tradition⁃al unit;3) the replacement cost from R22 heat pump and refrigeration system to CO2 system will increase 100% -200% and 20% -30%, respectively;4) CO2 has well application potential in heat pump water heater and refrigeration equipment area of ICR, but the re⁃frigeration cycle efficiency promotion, high efficiency components development and operation security protection under high pressure need further research.关键词
