Cooling system for refrigerator and refrigerator

Abstract

The invention provides a cooling system for a refrigerator and the refrigerator. The cooling system for the refrigerator comprises a compressor, a condenser, a throttling device, a flow dividing three-way valve and an evaporator component. A first end of the condenser is connected to an outlet of the compressor. A first end of the throttling device is connected to a second end of the condenser. An inlet of the flow dividing three-way valve is connected to a second end of the throttling device. The evaporator component comprises a first evaporator and a second evaporator. A first end of the first evaporator is connected to a first outlet of the flow dividing three-way valve. A second outlet of the flow dividing three-way valve and a second end of the first evaporator are connected to first ends of the second evaporator through a flow combining three-way valve respectively. A second end of the second evaporator is connected to an inlet of the compressor. According to the technical scheme, cooling speeds of different cavities can be guaranteed, large difference between the cooling speeds of different cavities is avoided, and the using effect of the refrigerator cannot be affected.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigeration system for a refrigerator and a refrigerator. Background technique [0002] The refrigeration system of the refrigerator proposed in the related art is as figure 1 As shown, the refrigerant enters the condenser 2' after passing through the compressor 1', and then enters the freezer evaporator 4' through the capillary tube 3', and the refrigerant after passing through the freezer evaporator 4' enters the refrigerator evaporator 5' and returns to the compressor Machine 1'. [0003] Since the refrigerating chamber evaporator 5' is connected in series with the freezing chamber evaporator 4' and is positioned after the freezing chamber evaporator 4', the problem of a slow cooling rate in the refrigerating chamber may occur. At the same time, when the temperature in the freezing chamber is low, the temperature in the refrigerating chamber is still high, which ca...

AI Technical Summary

Problems solved by technology

[0003] Since the refrigerating chamber evaporator 5' is connected in series with the freezing chamber evaporator 4' and is located behind the freezing chamber evaporator 4', the cooling speed of the refrigerating chamber is slow

At the same time, when the temperature in the freezer is low, the temperature in the freezer is still high, causing the refrigerator to continue to work without stopping, which increases the energy consumption of the refrigerator.
