Hot tool change of water cooling is the main cooling tower, cooling tower East Star is a main equipment of circulating cooling water system of water cooling heat exchanger used, it determines the performance of the condensing temperature of the refrigeration system, and the performance of the cooling water system was also decided.
Now the chiller commonly used cooling tower is usually strong cooling capacity, light weight and easy installation of glass steel suction counterflow cooling tower, cooling tower of the tower is made of glass steel, suction fan is arranged on the top of the tower, so that water and air are reverse flow. When air and water flow in reverse direction, as the water temperature is usually higher than the temperature of the air and water, the two carry out heat exchange and take away part of the heat.
The air enters the tower, tower from the lower circumference of the bottom-up flow, the upper cold water machine after use warm water by the pump into the cooling tower, the fan out from the top of the tower; a rotary water distributor of many nozzles or nozzle spray cooling down, the water flowing out from the bottom of the tower. So as to achieve the cooling system cooling purposes. Because the saturated vapor pressure of water is higher than that of air, the partial pressure of water evaporates and the latent heat of vaporization is taken away. Under the combined action of heat exchange, the temperature of the water decreases, the temperature of the air rises, the humidity rises and the relative temperature increases.
