The invention discloses a refrigeration device, comprising a refrigeration cycle which is at least composed of a compressor, a condenser, a swelling mechanism and an evaporator, wherein an R32 refrigerant and refrigerating machine oil are filled in the refrigeration cycle; the refrigerating machine oil is formed by mixing more than two of polyalkane glycol ether, polyvinyl ether, poly alpha olefin, alkylbenzene and mineral oil randomly; the second-layer separate temperature of one of the random more than two and the R32 refrigerant is lower than 10 DEG C below zero; the second-layer separate temperature of the other of the random more than two and the R32 refrigerant is higher than 10 DEG C below zero; the kinematic viscosity of the refrigerating machine oil is 2-100mm2/s when the temperature is 40 DEG C; more than one of antioxygen, acid catcher, antifoaming agent and extrusion antiwear agent is added into the refrigerating machine oil. The refrigerating machine oil and the R32 refrigerant have excellent dissolving capacity, the oil return property of the system is improved, and the reliability of the compressor and the system performance are improved.
