Document Type and Number:
WIPO Patent Application WO/2022/196171
Kind Code:
A1
Abstract:
Provided is a cold storage including: a box body that has a cold room; a compressor that constitutes a refrigeration circuit for cooling the inside of the cold room; a defrost heater for heating an evaporator that constitutes the refrigeration circuit; and a control device that controls the compressor and the defrost heater. The control device activates the defrost heater in the case where the compressor is not activated. In the case where the outside air temperature is equal to or higher than the room temperature of the cold room, the control device activates the compressor when the room temperature rises to a first threshold and stops the compressor when the room temperature drops to a second threshold lower than the first threshold. In the case where the outside air temperature is lower than the room temperature, the control device does not activate the compressor even when the room temperature rises to the first threshold.
