Description

Refrigerating apparatus Technical Field The utility model relates to the technical field of refrigeration, in particular to refrigeration equipment. Background The refrigeration principle of a refrigeration device mainly depends on the change of state of the refrigerant and the cyclic operation of the compressor. The refrigerant changes from a liquid state to a gas state in the evaporator, and absorbs heat in the refrigeration equipment, thereby reducing the temperature in the refrigeration equipment. The gaseous refrigerant is sucked by the compressor and compressed into a high-temperature and high-pressure gas, and then releases heat through the condenser to gradually condense into a liquid. After the high-pressure liquid is throttled and depressurized by a capillary tube, the high-pressure liquid enters the evaporator again, and continues to vaporize and absorb heat, so that a circulating refrigeration process is formed. In the refrigerating process of the evaporator, the temperature of the evaporator is far lower than that of surrounding air, water vapor in the air is easy to condense at the evaporator, and the evaporator is easy to frost under the condition of long-term working of the refrigerating equipment, so that the normal working of the refrigerating equipment is influenced.
