Abstract

The cooling tower is a device for making a cooling water in the air conditioning system of building, and there are many kinds of cooling tower system for air conditioner. In this paper, we introduced the water cooling system with an enclosed tank and water ejecting system for evaporating the water in tank. The city water was used for a working fluid, and the cooling water is generated by evaporating latent heat in the tank with a $25{\sim}50mmHg$. The time to reaching this vacuum pressure was about $20{\sim}30minutes$, and cooling water was obtained the value of temperature difference ${\Delta}T=7^{\circ}C$.
