Namely, the gaseous refrigerant is gradually condensed into the liquid refrigerant from top to bottom after entering the discharging pipe from the upper opening. The super strong wind force of the matched induced draft fan enables the spray water to completely and uniformly cover the surface of the coil pipe, and the heat exchange effect is greatly improved by the aid of the wind force of the water. The spray water with increased temperature is changed into gas state from part, a great amount of heat is taken away by wind by utilizing the latent heat of vaporization of water, water drops in hot gas are intercepted by the high-efficiency dehydrator, and the water with absorbed heat and the rest water are scattered into the packing layer, cooled by the flowing air, lowered in temperature, enter the water tank and then continue to circulate through the circulating water pump.
