Refrigerator

Abstract

A refrigerator comprises a refrigeration cycle having at least a compressor (19), an evaporator (20), and a condenser (21); and the refrigerator has the condenser (21) as the main component of a forced air cooling system, a flow channel switching valve (40) connected to the downstream side of the main component condenser (21), and a plurality of anti-moisture pipes (44, 41) downstream of the flow channel switching valve (40). When the refrigeration cycle is operating under normal conditions, refrigerant is channeled alternately to the plurality of anti-moisture pipes (44, 41), and when the refrigeration cycle is operating under overload conditions, refrigerant is channeled to the plurality of anti-moisture pipes (44, 41) in parallel.

Description

technical field [0001] The present invention relates to a refrigerator in which efficiency of a refrigeration cycle is improved by having a damper for blocking cold air in a freezer compartment and a refrigerator compartment, and cooling the freezer compartment and the refrigerator compartment individually using one evaporator. Background technique [0002] From the viewpoint of energy saving, among domestic refrigerators, there is a refrigerator in which efficiency of a refrigeration cycle is improved by cooling a freezer compartment and a refrigerator compartment individually using one evaporator. This is to improve the efficiency of the refrigeration cycle by cooling at a higher evaporating temperature than the freezer when cooling the refrigerator where the air temperature is higher. [0003] In addition, it has been proposed to cool the refrigerating room by cooling and heating of the low-temperature evaporator when the compressor is stopped, using dampers provided for ...

AI Technical Summary

Problems solved by technology

[0029] However, in the structure of the existing refrigerator, the refrigerant always flows in the anti-dew pipe 37 without being affected by the installation environment and operating state of the refrigerator, so the thermal load that invades the freezer compartment 18 from the anti-dew pipe 37 is caused, It causes the power consumption of the refrigerator to increase

[0030] In addition, the anti-dew pipe 37 made of a long thin-diameter pipe has a large pressure loss, and it becomes a main cause of an increase in the condensation temperature in an overload condition in which the circulation amount of the refrigerant is increased, and an increase in the power consumption of the refrigerator.
