ことを特徴とする冷凍装置。 In a refrigeration system having an air curtain at an opening, a plurality of evaporators are arranged in one ventilation passage from an air inlet to an air outlet of the air curtain, and a compressor and a water-cooled condenser are connected in series. A control valve is provided to control the amount of cooling water supplied to the condenser, and during normal operation, with the control valve open, the compressor and condenser are connected to the pressure reducer and the plurality of evaporators in parallel. On the other hand, when defrosting any of the evaporators, the refrigerant flows directly from the compressor and condenser to the evaporator to be defrosted with the control valve closed. 1. A refrigeration system comprising: a refrigerant path switching means for forming a refrigerant path from which the refrigerant passes through a pressure reducer and another evaporator that does not defrost, and then returns to the compressor.
