Description

Thermostatic storage device and refrigerator

technical field

The utility model relates to the technical field of refrigeration and freezing, in particular to a constant temperature storage device and a refrigerator.

Background technique

Air-cooled refrigerators will have different degrees of temperature fluctuations during stable operation and defrosting. During this process, the air temperature and humidity in the storage room will fluctuate periodically with the temperature of the cabinet. When the temperature rises, the relative humidity of the air drops due to the rising temperature of the storage space, causing the moisture in the food to evaporate. When the temperature drops, the relative humidity in the air increases, and some water vapor will condense in the refrigerator, causing frost on the surface of the food. Due to the temperature fluctuation of the refrigerator, the water in the food cells is continuously evaporated. The food stored in the freezer for a long time will appear dry after thawing, and the meat food will have the problem of meat texture after being cooked.

The temperature control range of the refrigerator compartment 11 is generally -5°C to 7°C. The temperature control range of the freezing chamber 12 is generally -18°C to -22°C. The storage compartment can also include a temperature-changing room and the like. The refrigeration mechanism is configured to generate cold energy, which is driven by the fan 16 and provided to each storage compartment through the air supply duct, so as to reduce the temperature in the storage compartment. Specifically, the refrigeration mechanism may be a compression refrigeration mechanism, which includes a compressor, a condenser, a throttling device, and an evaporator 15 . The compression refrigeration mechanism makes the evaporator 15 release the cooling capacity through the refrigerant compression cycle. Its working principle is: the compressor, as the power of the refrigeration cycle, is driven by the motor and rotates continuously, compressing the low-temperature and low-pressure refrigerant vapor to a high-temperature and high-pressure state . The condenser is a heat exchange device that uses the ambient cooling refrigerant to take away the heat from the high-temperature and high-pressure refrigerant vapor from the compressor, so that the high-temperature and high-pressure refrigerant vapor is cooled and condensed into a high-pressure and normal-temperature refrigerant liquid. The high-pressure and normal-temperature refrigerant liquid passes through the throttling device to obtain low-temperature and low-pressure refrigerant, which is then sent to the evaporator 15 to absorb heat and evaporate. The evaporator 15 is another heat exchange device, in which the throttling low-temperature and low-pressure refrigerant liquid evaporates into vapor, absorbs surrounding heat, lowers the surrounding temperature, and achieves the purpose of refrigeration.
