Heat pump clothes dryer exhaust air valve control method, computer equipment and heat pump clothes dryer

The invention relates to a heat pump clothes dryer exhaust air valve control method, computer equipment and a heat pump clothes dryer. The heat pump clothes dryer comprises a first heat pump system and a second heat pump system. The control method for the exhaust air valve of the heat pump clothes dryer comprises the following steps that the first operation pressure of a first heat pump system, the first actual opening degree of a first exhaust air valve and the second actual opening degree of a second exhaust air valve are obtained; and if the first operation pressure is higher than a first pressure threshold value, the opening degree of two exhaust air valves is adjusted according to a first preset condition, so that the operation pressure of the heat pump system is reduced. By arranging the first exhaust air valve and the second exhaust air valve, the adjustment of the clothes dryer can better meet the requirements of a double-heat-pump system; the opening degree of the two rows of air exhaust valves is ad
