Problems solved by technology

During a defrosting process, the defrosting heater needs to run for a long time, and this part of the electric energy cannot be used for refrigeration of the refrigerator, resulting in a waste of electric energy
In the condenser, a considerable amount of condensation heat is directly scattered into the air, which cannot be utilized, and also causes a waste of energy.

Abstract

The invention discloses an automatic defrosting system for an air cooling refrigerator and a control method of the automatic defrosting system. The automatic defrosting system comprises a compressor, a condenser, a drying filter, a capillary tube, a first evaporator, a second evaporator and a valve control system. Due to the fact that two systems are arranged, one system is used for defrosting operation, the specific valve control system is used for adjusting and switching to a refrigerant flow way, high-temperature refrigerant flowing out of the compressor is directly conveyed into an evaporator of the system to be defrosted, and the evaporator of the system to be defrosted serves as a condenser of the other system; heat of condensation is used for defrosting operation, the temperature of the evaporator of the system to be defrosted is increased, heat generated by the system is fully used, heat losses are reduced, system energy consumption is lowered, and defrosting time is relatively shortened; and no defrosting heater equipment needs to be used and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment and a control method thereof, in particular to a control method of an automatic frosting system of an air-cooled refrigerator. Background technique [0002] At present, the frost-free refrigerator mentioned in the related art, after entering the defrosting program, the compressor stops running, the refrigeration cycle stops, and the defrosting heater defrosts the evaporator. At this time, because there is no sustainable cooling capacity to provide The interior of the refrigerator is refrigerated, and the defrosting process of the refrigerator is generally relatively long. After the defrosting is completed, the temperature of the cabinet inside the refrigerator will rise to some extent. [0003] Most of the frost-free air-cooled refrigerators on the market use the defrosting heater to defrost when defrosting. The power of the defrosting heater is higher than the average power of the...
