The general cooling tower is a device for making a cooling water in refrigerant condensers or industrial process heat exchangers. The present cooling tower have defects with noises, complicated structure and environmental problems. <br/> In this paper, we constituted a new water cooling system by using a evaporating latent heat in an enclosed tank. and this system is consisted of an enclosed vacuum tank water driving ejector system. Several experimental cases were carried out for improvement methods of high vacuum pressure and water cooling characteristies. The ejector performance was tested in case of water temperature variation that flow in the ejector. Based on the vacuum pressure by water driving enjector, the water cooling characteristies were investigetesd for the vaporized air condensing effcts.

This paper is the study on the performance of cooling tower system by using the low vacuum. Currently, the cooling system is using at many parts of the industry. But, the present system have many problems for the cooling process. Thus, This research aimed for replacing the present cooling<br/> tower system. This new cooling tower system have a low vacuum, and have a ejector system to maintain a low pressure. As a main experimental parameter, we introduced a flowrate at the inlet ejector system.
