Document Type and Number:
Japanese Patent JP7270402
Kind Code:
B2
Abstract:
To provide a refrigeration device capable of suppressing reevaporation of drain water produced by melting of frost in a defrosting start period, and accelerating dryness of a cooling heat exchanger in a defrosting end period, to shorten a time required for defrosting operation.SOLUTION: A refrigerating device 30 for a cooling system is provided in a cooling system comprising a casing 10 forming a cooling chamber 13 and a transfer device 15. The refrigeration device 30 comprises a compressor, and a cooling heat exchanger 93 that exchanges heat between air in the cooling chamber 13 and a refrigerant. The refrigeration device performs a cooling operation of making the cooling heat exchanger 93 function as an evaporator to cool the air in the cooling chamber 13, and a defrosting operation of supplying the refrigerant discharged from the compressor to the cooling heat exchanger 93 to defrost the cooling heat exchanger 93.SELECTED DRAWING: Figure 1
