Title:
DIRECT-COOLING REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2014/205971
Kind Code:
A1
Abstract:
A direct-cooling refrigerator comprises a compressor (1), a condenser (2), a main refrigeration cycle capillary (3), a freezer evaporator (4), and a refrigeration evaporation pipe (5) that form a refrigerant loop; and further comprises a first switch apparatus (6), a defrost refrigeration evaporation pipe (9), and a second switch pipe (7). The first switching apparatus (6) enables an egress of the compressor (1) to communicate with an ingress of the condenser (2) during refrigeration, and enables the egress of the compressor (1) to communicate with an ingress of the freezer evaporator (4) during defrost. The second switch apparatus (7) enables an egress of the refrigeration evaporation pipe (5) to communicate with an ingress of the compressor (1) during refrigeration, and enables an egress of the defrost refrigeration evaporation pipe (9) to communicate with the ingress of the compressor (1) during defrost. The first and second switch apparatuses (6, 7) are set in the direct-cooling refrigerator, so that a main refrigeration cycle system and a defrost refrigeration system can be switched according to needs, and automatic defrost is implemented in a freezer.
