Method and device for controlling semi-closed heat pump drying equipment and semi-closed heat pump drying equipment

The invention relates to the technical field of heat pump drying equipment, and discloses a method for controlling semi-closed heat pump drying equipment which comprises a fresh air valve, an exhaust valve and an electric heating module. Obtaining the tobacco leaf drying time of the semi-closed heat pump drying equipment; determining the drying period of the tobacco leaves according to the drying time; and the fresh air valve, the exhaust valve and the electric heating module are adjusted according to the drying period. Therefore, under the condition of refrigerant leakage, the fresh air valve, the exhaust valve and the electric heating module of the semi-closed heat pump drying equipment are adjusted according to the drying period determined by the drying time of tobacco leaf drying, so that the quality of tobacco leaves is not easy to deteriorate under the condition of refrigerant leakage of the semi-closed heat pump drying equipment in the tobacco leaf drying process; and normal baking of the tobacco leave
