PROBLEM TO BE SOLVED: To effectively suppress power devices in a power supply device for driving a compressor motor from being frosted even during power outage in a refrigeration device including a cooler for cooling the power supply device with refrigerant.SOLUTION: A refrigeration device includes: a compressor; a condenser; an expansion valve; and an evaporator, and also includes a cooler for cooling a power supply device (P) for supplying power to a drive motor of the compressor with refrigerant output from the condenser. During power outage, the power is supplied to a controller (7) from a control power supply (8) to which electric energy is supplied from storage means (a smooth capacitor) (12) included in the power supply device (P), and the controller (7) controls pressure control means (22) connected to the cooler and suppresses power devices in the power supply device (P) from being frosted. |
