1. design: incorrect equipment selection, compressor placed far away from the machine, small model configuration led to long working hours of the compressor, insufficient insulation thickness, and cold bridge led to cold leakage. The refrigerator consumes a lot of electricity.
2. Operation: There is no air curtain machine when the garage door is frequently opened and closed, which leads to the loss of garage cooling capacity and the refrigerator can't work effectively all the time. Opening and closing the garage door for a long time will lead to high power consumption.
3. Equipment: Equipment failure, evaporator frosting, compressor failure, copper tube damage and refrigerant leakage will also lead to an increase in electricity bills.
