Abstract
A refrigeration device includes a radiator, an evaporator, a compressor, a heater and a control device. The radiator causes a refrigerant to radiate heat. The evaporator causes the refrigerant to evaporate. The compressor compresses the refrigerant circulating between the radiator and the evaporator. The heater heats lubricating oil in the compressor. The control device controls the heater so that an oil temperature of the lubricating oil in the compressor reaches an oil temperature target value obtained by adding a predetermined temperature to saturation temperature of the refrigerant in the compressor.

A refrigeration device, comprising:
- a radiator configured to cause a refrigerant to radiate heat;
- an evaporator configured to cause the refrigerant to evaporate;
- a compressor configured and arranged to compress the refrigerant circulating between the radiator and the evaporator;
- a heater configured to heat lubricating oil in the compressor;
- and
- a control device configured to control the heater so that an oil temperature of the lubricating oil in the compressor reaches an oil temperature target value obtained by adding a predetermined temperature to saturation temperature of the refrigerant in the compressor.
