Air conditioning system with solid wheel adsorption dehumidification has advantages of environmental protection and energy-saving. It mainly processed fresh air. Aiming at the problem of high consumption for regenerative heating in the conventional system, this paper proposes a heat recovery air conditioning system with adsorption dehumidification driven by solar energy, which mainly processes fresh and returns air. Three types of heat recovery schemes are studied. According to the weather conditions of 7 humid regions in China in summer, the operation plans and energy consumption of the system are discussed. The results show that the typical air conditioning heat recovery system with two-stage heat recovery of exhausted air is the most energy-saving, and the payback period of the system is only 4 years; the total energy consumption of the front-heat recovery system is lower than the back-heat recovery system.
