Abstract

The present invention relates to the field of refrigeration system maintenance. Aiming at the problem that the existing refrigerant charging method is complicated, a refrigerant charging method is proposed, which includes: sending a charging command to the charging device and the refrigeration system to be filled with refrigerant, according to The charging command fills the components to be charged with refrigerant; the ambient temperature, the compressor discharge temperature and the winding temperature of the compressor motor are obtained in real time after the refrigeration system operates according to the charging command and the corresponding charging operating conditions, and recorded The temperature difference between the winding temperature and the exhaust temperature is the actual temperature difference, and the corresponding relationship between the predicted preset operating conditions and the temperature difference of the refrigeration system with the refrigerant amount as the target amount under the preset operating conditions is obtained; the refrigerant amount is obtained according to the corresponding relationship is the estimated temperature difference of the target refrigeration system under charging operation conditions; judge whether the actual temperature difference matches the expected temperature difference, and if so, send a stop command to the charging device to stop charging the refrigerant. The invention is applicable to charging of refrigerant.

Description

Technical field[0001]The present invention relates to the field of refrigeration system maintenance techniques, and in particular, to a refrigerant feeding system and method.Background technique[0002]The refrigeration system is connected by a compressor, a condenser, a throttle apparatus, and an evaporator, and the inside is filled with the refrigerant, wherein the compressor is common, the compressor is completed from suction to the exhaust. The process is achieved by motor operation. The amount of refrigerant should be appropriate, and it cannot be less. The reduction in the refrigerant can cause system performance, decrease in energy efficiency; if there is more, it may cause damage to the compressor motor, which may eventually cause the motor to be burned, or cause the motor to be short-circuited and the compressor housing charge. Similarly, the refrigeration system can also cause excessive energy and energy efficiency ratio of the system. In fact, during the installation proces...
