うにしたことを特徴とする冷凍装置。 A refrigeration cycle is constituted by a compressor, a condenser, an expansion valve, and an evaporator, and a defrosting hot gas bypass pipe is branched from a branch point provided in the discharge pipe of the compressor and connected to the inlet side of the evaporator. In the refrigeration system, a solenoid valve is provided between the branch point and the inlet of the condenser and on the hot gas bypass pipe, respectively, wherein the solenoid valve between the branch point and the condenser inlet is an energized closed type solenoid. A refrigeration system characterized in that the solenoid valves on the hot gas bypass pipe are energized open type solenoid valves, and each of the solenoid valves is energized only during defrost operation.
