In order to meet the new environmental requirements of drying technology and reduce energy consumption costs, this paper uses solar energy and air energy to combine multiple heat sources to propose a heat pump-solar drying system for crop drying. Among them, the heat pump system is a dual evaporator parallel mode, and the solar energy adopts the form of comprehensive application in the system. The operation principle of the system is analyzed, and the operation effect of the vacuum tube hot water collection system is obtained through Trnsys simulation, and a multi-energy complementary control method is proposed for the system, which makes the system operation more energy-saving and flexible.
