PROBLEM TO BE SOLVED: To provide a highly reliable refrigeration device wherein appropriate protection control is carried out regardless of the external air temperature or the type of refrigerant used in the refrigeration device when the discharge temperature of the refrigerant is being measured at the outside of a compressor.SOLUTION: An air-conditioning device 1 is provided with a refrigerant circuit, a discharge pipe temperature sensor 51, a protection control part 41c, and a determination temperature modification part 41d. The refrigerant circuit includes a compressor 31 for compressing a refrigerant. The discharge pipe temperature sensor detects the temperature of the refrigerant discharged from the compressor at the outside of the compressor. The protection control part carries out protection control of the compressor when the discharge pipe temperature detected by means of the discharge pipe temperature sensor surpasses a determination temperature. The determination temperature modification part modifies the determination temperature in accordance with information pertaining to the external air temperature and/or information pertaining to the type of the refrigerant. |
