[0002] Refrigerators and air conditioners are necessary household appliances for people’s lives. The motor control systems of these refrigeration or heating equipment mostly use the upper and lower limits of the temperature to be set in the control circuits of these equipment. When the temperature is higher than the upper limit of the temperature , the control circuit controls the motor to start, and the motor starts to work. When the temperature is lower than the set temperature lower limit, the control circuit controls the motor to stop working, and the motor stops running; but this control method is not sensitive enough. When the control circuit fails, it cannot Realize the purpose of intelligent control
