REVERSIBLE DIRECT-COOLING SYSTEM, REFRIGERATOR AND REFRIGERATION CONTROL METHOD

WIPO Patent Application WO/2016/115925

A1

A reversible direct-cooling system (100'), a refrigerator and a refrigeration control method. The reversible direct-cooling system (100') comprises a compressor (1), a condenser (2), a dry filter (3), throttling devices (41, 42), evaporators (5, 6), a return air pipe (7) and a four-way valve (8). The evaporators (5, 6) comprise a refrigerating evaporator (5) and a freezing evaporator (6) arranged in series. The four-way valve (8) comprises a first port (A) connected to the throttling devices (41, 42), a second port (B) connected to the refrigerating evaporator (5), a third port (C) connected to the freezing evaporator (6), and a fourth port (D) connected to the return air pipe (7). By the use of the reversible direct cooling system (100') with this construction and the refrigeration control method, the area matching problem of the evaporator of the refrigerator under different ambient temperatures can be solved, with the effects of saving energy and reducing consumption, and meanwhile the manufacturing cost can be reduced.
