Problems solved by technology

[0004] Traditional household refrigerators only use the cooling effect of the refrigeration system to cool and keep the objects in the freezer or cold storage room fresh. The heating effect of the refrigeration system is less utilized, and it is only used to prevent dew on the door seal of the freezer

Abstract

The invention discloses a heat storage unfreezing and heat preservation system for a household refrigerator, and belongs to the field of household appliances. A heat storage unfreezing chamber is additionally arranged on the basis of a conventional two-chamber refrigerator. The conventional refrigerator is divided into a freezing chamber and a refrigeration chamber; on the basis of the conventional refrigerator, the heat storage unfreezing chamber is additionally arranged; in a refrigerant circulating pipeline of the refrigerator, a pipeline between a compressor and a condenser is connected to the heat storage unfreezing chamber; condensing heat of the compressor is used for heating a heat storage material in the heat storage unfreezing chamber; the heat storage material is an organic phase change composite material, so that the condensing heat can be stored in the form of phase change heat storage; when food needs to be unfrozen, heat is released, so that the aims of quick unfreezing and energy conservation are fulfilled.

Description

technical field [0001] The invention relates to a heat storage, thawing and heat preservation system for household refrigerators, belonging to the technical field of refrigeration equipment. Background technique [0002] As a device for food storage and preservation in public households, refrigerators have become an indispensable item for every family. my country is a major producer and consumer of refrigerators and other small refrigeration devices. According to statistics, the total output of refrigerators in 2012 was 66 million units, and the total domestic refrigerator market sales were 41 million units. At present, the total number of refrigerators in my country has exceeded 250 million, close to 300 million. [0003] At present, most of the traditional refrigerators on the market are two-chamber or three-chamber refrigerators. The refrigeration system pipeline of the refrigerator includes compressor, condensation pipeline, anti-dew pipe, dry filter, capillary tube, fr...
