The invention discloses a solar energy driven recuperative solid drying and dehumidifying air conditioner system. The solar energy driven recuperative solid drying and dehumidifying air conditioner system comprises a first dehumidifying heat exchanger and a second dehumidifying heat exchanger, wherein the first dehumidifying heat exchanger and the second dehumidifying heat exchanger are set to work simultaneously so as to realize continuous running of the system. In a dehumidifying process, cooling water generated by a cooling tower is fed into the first dehumidifying heat exchanger, and takes away adsorption heat generated in an adsorption dehumidifying process of a drying agent; and meanwhile, hot water from a recuperative water tank is fed into the second dehumidifying heat exchanger at first for a period of time, then hot water of a thermal-insulation water tank of a solar thermal collector is fed into the second dehumidifying heat exchanger, the drying agent is desorbed and regenerated by the hot water, and produced regenerated air heats the hot water in the recuperative water tank. The solar energy driven recuperative solid drying and dehumidifying air conditioner system has the advantages of simple structure, easiness in operation, low cost, low investment and the like; and the regenerated air with high temperature and high humidity can be utilized efficiently, the efficiency of the integral system is greatly improved, and thermal pollution of the environment is reduced.
