R502 is an azeotropic solution formed by mixing R12 and R22 at the percentages of 51.2% and 48.8%.
The refrigerant mixture of R417A mixed refrigerant R134a, R125 and R600 refrigerant from the refrigerant.
R408A can be used as a transitional alternative refrigerant for low temperature and medium temperature commercial refrigeration systems.
R507A is a long-term replacement for R-502 refrigerant with a zero ODP value and does not contain any ozone depleting substances.
R410A is a new type of environmentally friendly refrigerant, the working pressure is about 1.6 times that of ordinary R22 air conditioners, and the cooling (heating) efficiency is high.
R407C is a mixture of R32 refrigerant and R125 refrigerant plus R134a refrigerant in a certain proportion. It is an environmentally friendly refrigerant that does not destroy the ozone layer.
