摘要:
An apparatus having a refrigeration cycle using a flammable refrigerant, comprises an oil-free compressor (100, 200) a condenser (19), an expansion device (20) and an evaporator (21), wherein an amount of lubricant in the oil-free compressor (100, 200) is equal to or smaller than 3cc. With this structure, the charging amount of the flammable refrigerant into the refrigeration cycle can be reduced, and the safety of the apparatus having a refrigeration cycle can be enhanced.
