Abstract: Based on the existing refrigeration system of household inverter air conditioning, this paper proposes to use refrigerant totake away the heat generated by outdoor electrical control when the whole machine is running in high temperature environment in summer, so as to reduce the temperature of outdoor electrical control module and improve the reliability of electronic control operation, and to run higher frequency at the same temperature of refrigeration environment, so as to improve the refrigeration in high temperature environment in summer. Effectiveness, improve user satisfaction. In practical application, the effect of refrigerant cooling scheme on high temperature refrigeration effect of inverter air conditioning and the temperature of outdoor electrical control module are analyzed and compared, which provides new research ideas and directions for inverter air conditioning products.
