An energy-saving refrigerator and its fast thawing method and system

Abstract

The invention relates to the field of refrigerator equipment, and discloses an energy-saving refrigerator, which includes a refrigerating room and a variable temperature room. The variable temperature room is provided with a variable temperature evaporator and a temperature variable fan. It forms a circulating air path with the return air pipe, and the air supply pipe is provided with a damper. When the refrigerated room needs to be refrigerated or the variable room needs to be heated and thawed, the variable temperature fan and the damper are opened to conduct the circulating air path to form a convection exchange. Heat, so that the cold capacity of the variable room is used to support the refrigeration of the refrigerator, and the heat of the refrigerator is used to support the temperature increase of the variable room. The invention also discloses a quick thawing method and system using the energy-saving refrigerator. By adopting the present invention, the energy in the refrigerating room and the temperature-changing room can be rationally utilized, and the frozen food in the temperature-changing room can be thawed quickly and the refrigerating room is refrigerated without increasing the energy consumption of the whole machine and saving the cost of product materials.

Description

technical field [0001] The invention relates to the field of refrigerator equipment, in particular to an energy-saving refrigerator and its fast thawing method and system. Background technique [0002] Refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, which brings convenience to food preservation. When the food temperature reaches the freezing temperature (such as ≤-18°C), it can prolong the preservation time of food, so meat, fish, etc. need to be preserved for a long time The food for a long time is often placed in the freezer or the changing room (at this time the changing room reaches the freezing temperature), but due to the low temperature of the freezing room, the internal moisture of the meat, fish and other foods placed in the freezing or changing room has been frozen, and cannot Use immediately for cooking, need to thaw first. General user thawing schemes are as follows: [0003] The first is to take out the frozen food ...

AI Technical Summary

Problems solved by technology

[0005] The third is to put the food that needs to be thawed into the refrigerator. The pain point is that the refrigerator needs to have available space, and it needs to be transported manually. It takes a long time to thaw, which is laborious and laborious.

Moreover, the adjacent rooms are normally refrigerated, but the variable temperature room needs heaters to be heated. The variable temperature heater consumes electricity and wastes energy. Increased overall energy consumption
