refrigerator refrigeration cycle

Abstract

A refrigerating cycle of a refrigerator, comprising: a first refrigerating cycle, wherein a first refrigerant flows along a first refrigerating pipe; and a second refrigerating cycle, wherein a second refrigerant flows along a second refrigerating pipe, the cycle comprising: The first compressor and the second compressor; the first expansion valve and the second expansion valve; and the first evaporator and the second evaporator; the combined condenser, including: the first condensation pipe and the second condensation pipe, which constitute the first evaporator and the second evaporator; A compressor and a second compressor are respectively connected to a part of the first refrigeration pipe and the second refrigeration pipe of the first expansion valve and the second expansion valve; and heat exchange fins contacting the surfaces of the first condensation pipe and the second condensation pipe . The first condensing pipe and the second condensing pipe share at least part of the heat exchange fins, and the first condensing pipe and the second condensing pipe are bent several times to form each of the first refrigerating pipe and the second refrigerating pipe having a predetermined width and length parallel to each other. The zigzagging lines are vertically arranged, and the heat exchange fins are inserted between the adjacent condensation pipes.

Description

technical field [0001] The present disclosure relates to a refrigeration cycle of a refrigerator. Background technique [0002] In the refrigerator according to the related art, the refrigerant is transferred from one compressor to the evaporators respectively arranged at the rear sides of the refrigerator compartment and the freezer compartment, and then the opening degree of the valve arranged in each evaporator is adjusted to alternately To implement the operation of cooling the freezer and refrigerator. Alternatively, the freezer is cooled by using a single evaporator arranged on one side of the freezer, and then a damper is used to divert the cool air to the refrigerator. [0003] However, in the case of the above structure, the temperatures required for the refrigerator compartment and the freezer compartment are different from each other. Therefore, in order to achieve the desired temperature of the two storage compartments having a large temperature difference betw...

AI Technical Summary

Problems solved by technology

[0004] However, in the case of double-cycle refrigerators, the following limitations still arise

That is, in a dual cycle, one of the limitations is having to install two compressors and condensers in the mechanical room

As a result, the volume of the machinery room may increase, and therefore the volume of the storage room may decrease

[0005] In addition, if two compressors and a condenser are installed in a limited mechanical room, the size and capacity of the condenser are limited, resulting in a limitation of the heat dissipation area for heat dissipation

[0006] In addition, when two condensers and two compressors are arranged in the mechanical room, the flow resistance of the indoor air forced into the mechanical room by the condensing fan will reduce the heat dissipation efficiency of the condenser
