s301: starting the clothes dryer, and acquiring the air inlet temperature through the temperature sensor;
an air inlet temperature point is arranged between the main condenser and the circulating fan, and a temperature sensor is arranged at the air inlet temperature point to monitor and acquire the temperature of the current dry hot air transmitted from the main condenser;
specifically, after the clothes dryer is started, a temperature sensor arranged between the main condenser and the circulating fan starts to work, and the current temperature of the hot dry air transmitted by the main condenser, namely the current air inlet temperature, is obtained, so that the real-time monitoring of the temperature of the air entering the clothes drying roller is realized.
S302: when the current air inlet temperature is higher than a first preset temperature, starting the fan so that the fan blows to the auxiliary condenser;
the fan is used as a part of the auxiliary cooling unit and is arranged outside the heat pump unit and used for accelerating heat exchange of the refrigerant in the auxiliary condenser and reducing the temperature of the refrigerant in the auxiliary condenser, so that the temperature of the refrigerant in the auxiliary condenser is quickly reduced when the refrigerant passes to the evaporator, and the supercooling degree of the evaporator is improved;
