The utility model relates to a solar air-conditioning device which is a cold/hot wind solar absorption-type air-conditioning device. The solar air-conditioning device comprises a heat collector, a cold/hot wind absorption-type air conditioner, a hot water tank and a cold water tower. The cold/hot wind absorption-type air conditioner comprises an absorber, a heat exchanger, a generator, a condenser and an evaporator. The water inlet of the solar heat collector communicates with the first water outlet of the hot water tank via a pipeline and a hot water-circulating water pump. The water outlet of the solar heat collector communicates with the first water inlet of the hot water tank via a pipeline. The second water outlet of the hot water tank communicates with the hot water inlet of the generator via a pipeline and a hot water pump. The solar air-conditioning device has the advantages of reasonable and compact structure, easy use and capability of cooling the air by the one-time heat-transfer. Under the condition of the same air-conditioning temperature, the evaporation temperature of the cooling medium is increased by about 4 DEG C to 5 DEG C, thereby effectively increasing the refrigerating efficiency. Under the same condition of driving the heat source, the cooling capacity is increased. The solar air-conditioning device can also provide the hot air for the heat supply in winter.
