Refrigerator and refrigerating system thereof

Abstract

The invention provides a refrigerating system and a refrigerator comprising the refrigerating system. The refrigerating system comprises a compressor, a condenser, a switching valve, an evaporator and a quencher, wherein the input end of the condenser is connected with the output end of the compressor; the switching valve comprises a first port, a second port and a third port; the first port of the switching valve is connected with the output end of the condenser; the input end of the evaporator is connected with the second port of the switching valve, and the output end of the evaporator is connected with the input end of the compressor; the input end of the quencher is connected with the third port of the switching valve, and the output end of the quencher is connected with the input end of the evaporator. According to the refrigerating system provided by the embodiment of the invention, when the first port and the second port of the switching valve are opened and the third port is closed, a normal refrigerating mode can be realized; when the first port and the third port of the switching valve are opened and the second port is closed, a quenching mode can be added.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigeration system and a refrigerator with the refrigeration system. Background technique [0002] Ordinary refrigerators are mainly equipped with refrigerating chambers and freezing chambers. In addition, a few refrigerators also have cooling chambers and ice chambers. The temperature requirements of each chamber are as follows (national standard): [0003] cold room Freezer ice house cooling room 0≤t≤10℃ t≤-18℃ -2≤t≤3℃ 8≤t≤12℃ [0004] The refrigerator is also equipped with quick-cooling and quick-freezing functions: that is, the compressor is not stopped for refrigeration (in normal use, the refrigerator compressor is turned on and off), so as to achieve rapid cooling. [0005] With the acceleration of people's life rhythm, consumers hope that after putting the purchased food (especially beer, beverage and dairy...

Problems solved by technology

One by one, this is unacceptable to users

[0006] Disadvantages of the existing technology: 1. It takes a long time and cannot meet the user's "eat and drink" needs; 2. If the "quick cooling" is activated, the temperature of other foods that have been stored for a period of time in the box may exceed zero and cause cold injuries; 3. .Ordinary "quick cooling" compressor does not stop and consumes a lot of power
