Independent refrigeration electric refrigerator

Abstract

An electric refrigerator with individual refrigeration for freezing chamber and cold storage chamber is composed of casing, freezing chamber, cold storage chamber, compressor, condenser, expansion valve, fan and evaporator. Its features are that said freezing chamber and cold storage chamber have individual cold air channels, one for each chamber, and a single-evaporator or serially connected two evaporators are used for both chambers. Its advantage is high refrigerating efficiency.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a refrigerator. Background technique [0002] Refrigerator is a kind of necessities of life, and it can freeze or keep fresh the food stored in the refrigerator for a period of time. The working principle of an ordinary refrigerator is to generate low temperature inside the refrigerator through repeated cycles of compression, condensation, expansion, and evaporation of the refrigerant. [0003] The structure of an ordinary refrigerator mainly includes: a compressor, a condenser, an expansion tube and an evaporator. The function of the compressor is to compress the refrigerant from a low-temperature / low-pressure gaseous state to a high-temperature / high-pressure gaseous state; the function of the condenser is to condense the high-temperature / high-pressure gaseous refrigerant output from the compressor into a low-temperature liquid state; the function of the expansion tube is to make the c...

Problems solved by technology

However, when the heater is driven for defrosting, cold air delivery must be stopped for a period of time

In addition, since the heater will generate heat when defrosting, the temperature inside the refrigerator will rise, resulting in an increase in the refrigeration load when the refrigeration is restarted, reducing the refrigeration efficiency.
