REFRIGERATOR AND CONTROL METHOD

摘要

Disclosed is a refrigerator, comprising a refrigeration compartment and a freezer compartment. A first refrigeration evaporator (1) and a second refrigeration evaporator (2) are provided in the refrigeration compartment. A freezer evaporator (3) is provided in the freezer compartment. The first refrigeration evaporator (1) and the second refrigeration evaporator (2) after being coupled in parallel are coupled in series with the freezer evaporator (3). Two mutually independent refrigerant circulation loops are formed by means of a two-position three-way electromagnetic valve (4) connected between a condenser (5) and a compressor (6). A control unit switches the two-position three-way electromagnetic valve (4). The refrigerator can switch the refrigeration compartment to a micro-freezer compartment according to user requirements, on the one hand meeting user requirements on the freezer compartment under special circumstances and on the other hand, food in the micro-freezer compartment does not require a very long time to defrost, thus the refrigerator does not need the addition of a variable temperature chamber. The structure is simple and easy to realise.
