The invention discloses a multi-energy complementally driven dehumidification air-conditioning system which comprises a room internal partition wall, a room wall, a hollow fiber membrane, an indoor air return port, an indoor circulating fan, a wind driven generator, a storage battery, a solar thermal collector, a heat exchanger, an ultrasonic atomizer, an ultrasonic generator, a solution regenerator, an energy storage reservoir, a solution collection reservoir, a solution circulating pump, a liquid return pump and a plurality of valves. The solution regenerator is composed of an atomizing chamber, an air inlet, a solution baffle, a demister and an exhaust fan. The multi-energy complementally driven dehumidification air-conditioning system uses solar energy as the regeneration thermal source of a dehumidification solution, improves dehumidification solution regeneration efficiency by aid of the ultrasonic atomization effect, solves the problem of the solution dehumidification system that the air contains liquid by aid of the hollow fiber reverse osmosis membrane, is provided with electricity through wind power generation, and achieves diversification of system driving energy. The multi-energy complementally driven dehumidification air-conditioning system can meet architectural indoor dehumidification requirements in high-humidity seasons such as the spring and the summer, can supply heat to the buildings in summer, is especially suitable for being used in moist areas with cold winter and hot summer, and has remarkable social benefit and economic benefit.
