Description

Refrigerating system and refrigerating equipment Technical Field The application relates to the technical field of electric appliance manufacturing, in particular to a refrigerating system and refrigerating equipment. Background The refrigerator is widely applied to refrigeration equipment in the scenes of families, businesses and the like, and can effectively inhibit the growth of microorganisms and the chemical reaction rate by maintaining a low-temperature environment, so that the functions of food preservation and storage are realized. The existing refrigerator refrigerating system mainly comprises a compressor, a condenser, an evaporator, a capillary tube and other core components, the working principle of the refrigerator refrigerating system is based on the cyclic phase change of refrigerant, the compressor compresses low-temperature low-pressure refrigerant gas into high-temperature high-pressure gas, the high-temperature high-pressure gas is cooled and condensed by the condenser to be liquid, then liquid refrigerant enters the capillary tube, the liquid refrigerant is throttled and depressurized to become a low-temperature low-pressure gas-liquid mixed state, the liquid refrigerant enters the evaporator and then is rapidly evaporated to absorb heat, the temperature in the refrigerator is reduced, the evaporated low-temperature low-pressure refrigerant gas is sucked by the compressor again, and the refrigerant effect is continuously realized by cyclic reciprocation. The capillary tube plays a vital role in the refrigeration system, and is used as a throttling element for throttling and reducing the pressure of the high-pressure liquid refrigerant by utilizing the slender pipe diameter structure, so that the refrigerant can be quickly evaporated and absorbed after entering the evaporator, and refrigeration cycle is realized. However, since the flow rate of the freezing capillary tube in the existing refrigerator is generally fixed, when the rotation speed of the compressor is fixed, the cooling rate of the refrigerator is also fixed, so that the requirements of users on changing the cooling rate and realizing lower cooling temperature in certain scenes cannot be met.
