Document Type and Number:
WIPO Patent Application WO/2018/074272
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a refrigeration device which introduces a refrigerant which has changed state as a result of defrosting, into another cooling unit via a defrosting liquid pipe, and evaporates said refrigerant. This refrigeration device, in which a plurality of cooling units provided with expansion valves and evaporators are connected in parallel to a refrigerator unit, is provided with a defrosting liquid pipe which connects the downstream side of the evaporator of one cooling unit to the upstream side of the expansion valve of another cooling unit. The refrigeration device enables a refrigerant processing operation to be performed in which, while the evaporator of the one cooling unit is being defrosted by the heat of refrigerant at an outlet of the refrigerator unit, refrigerant supercooled as a result of the defrosting is introduced into the evaporator of the other cooling unit via the defrosting liquid pipe.
