[0016] Example one
[0017] See Figure 1-Figure 2 The refrigeration device includes a refrigeration cycle consisting of at least a compressor 1, a condenser 22, an expansion mechanism 23 and an evaporator 24. The refrigeration cycle is filled with R32 refrigerant and refrigerating machine oil. The refrigerating machine oil is made of polyalkane two Alcohol ether, polyvinyl ether, poly alpha olefin, alkyl benzene and mineral oil are mixed together.
[0018] For example, refrigerating machine oil is made of polyalkane glycol ether and polyvinyl ether; or, refrigerating machine oil is made of poly-alpha olefin, alkylbenzene and mineral oil; or, refrigerating machine oil is made of polyalkane glycol ether, Polyalphaolefin, alkylbenzene and mineral oil are mixed together, and so on.
[0019] Wherein, the two-layer separation temperature of any two or more of one with R32 refrigerant is below -10°C, and the two-layer separation temperature of any two or more of another with R32 refriger...
