Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] As shown in the drawings, the refrigeration system of the present invention is applied to a certain refrigerator, and the thermal load of the refrigerator is Q0.
[0024] The first refrigeration circuit of the refrigeration system of the present invention, that is, the refrigeration module, includes a compressor 1, a condenser 2, a dry filter 3, a three-way reversing valve 4, a first capillary tube 7, a main evaporator 10, and a gas-liquid Separator 11; the operation of the first refrigeration circuit can provide an evaporation temperature of -30°C, and due to the limitation of flow rate and evaporation area, this circuit can provide a small cooling capacity Q 1 ;
[0025] The second refrigeration circuit, that is, the quick-freezing module, includes a compressor 1, a condenser 2, a dry filter 3, a three-way reversing valve 4,...
