Integrated air-water evaporative cooling air conditioning system

The utility model discloses an integrated air-water evaporative cooling air conditioning system which comprises a unit shell, and a primary air inlet and a primary air outlet are formed in the two opposite side walls of the unit shell respectively. A fresh air filter, an indirect evaporative cooling precooler, a direct evaporative cooler, a water baffle and an EC fan b are sequentially arranged in the unit shell according to the flowing direction of primary air after the primary air enters the unit shell. A secondary air exhaust outlet is formed in the position, corresponding to the top of the indirect evaporative cooling precooler, of the unit shell, the primary air exhaust outlet is opposite to the room air inlet, and the direct evaporative cooler is connected with a U-shaped heat exchanger at the tail end of an air conditioner in a cold supply room through a water return pipeline and a water supply pipeline. The air conditioning system not only can prepare cold air, but also can prepare cold water, and the
