Refrigerator with variable freezing capacity

Abstract

The invention relates to a refrigerator with variable freezing capacity, wherein an evaporator is respectively arranged in a refrigerating chamber and a freezing chamber, a main evaporator and an auxiliary evaporator are arranged in the freezing chamber, the branches of the main evaporator and the auxiliary evaporator are connected in parallel onto a main refrigerating loop comprising a compressor, a condenser and a capillary, and an electromagnetic valve is arranged on the branch of the auxiliary evaporator. The refrigerator has variable freezing capacity, the freezing capacity of the freezing chamber can be quickly improved under the working conditions of a large amount of stored foods and high temperature and can be adjusted under the conditions of a small amount of foods and smaller low-temperature working-condition loads, and the operating time of the compressor is reduced to reduce the energy consumption so that the refrigerator has higher energy-saving effect when in use.

Description

technical field [0001] The invention relates to the technical field of refrigeration for refrigerators, and more specifically relates to a refrigerator with variable freezing capacity. Background technique [0002] Compressor-refrigerated refrigerators occupy most of the market share due to their economical reliability, mature technology, long life and convenient use. It consists of key components such as compressors, condensers, dry filters, capillary tubes, and evaporators. Composition, through the refrigeration system, the circulation of the refrigerant is used for heat exchange, and the heat in the refrigerator is transferred to the air outside the refrigerator, so as to achieve the purpose of cooling the refrigerator. At present, during the use of the refrigerator, the freezing capacity of the refrigerator is basically unchanged. The amount of food stored by the user varies. If the freezing capacity of the refrigerator is small, when a large amount of food needs to be f...

AI Technical Summary

Problems solved by technology

At present, during the use of the refrigerator, the freezing capacity of the refrigerator is basically unchanged. The amount of food stored by the user varies. If the freezing capacity of the refrigerator is small, when a large amount of food needs to be frozen, the cooling capacity will be different Insufficient, so that the temperature of the food can not be lowered for a long time, affecting the storage quality of the food

If the refrigerator is designed with a larger food freezing capacity, it will waste more electric energy and pay a higher cost for occasions where the amount of food frozen is small

The refrigeration system of this kind of refrigerator usually adopts a relatively simple control system. For example, putting food in a certain temperature zone may trigger the refrigeration system to start working, resulting in too low temperature in the freezing zone, which affects the storage quality of food.
