Hot tool change of water cooling is the main cooling tower, cooling tower is the main equipment in the circulating cooling water system of water cooling heat exchanger used, its performance determines the condensing temperature of the refrigeration system, also determines the performance of the cooling water system.
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, the water tower is arranged on the top of suction fan, the reverse flow of water and air. When the air and water reverse flow, because the water temperature is usually higher than the temperature of the air water, the two heat exchange, 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 purpose of cooling the cooling system. Because the saturated vapor pressure of water is higher than the partial pressure of water vapor in the air, some of the water evaporates and takes away the latent heat of vaporization. Under the combined action of heat exchange, the temperature of the water decreases, the air temperature rises, the humidity rises, and the relative temperature increases.
