Claims

[Scope of utility model registration request]

An evaporator that forms part of the refrigeration cycle to cool the inside of the storage room to a predetermined temperature, and a discharge side of the compressor that guides the high-temperature refrigerant discharged from the compressor to the evaporator during defrosting operation. A cooling unit comprising: a hot gas bypass defrosting circuit that connects the inlet side of the evaporator to the inlet side of the evaporator; and a capillary tube interposed on the side of the hot gas bypass defrosting circuit that is close to the evaporator.
