Evaporative condenser, is commonly known as a name, also known as closed cooling tower. In fact, it is also known as closed cooling tower, the use of evaporation of spray water, brought out of the tower by the air, for cooling the circulating medium in the heat transfer tubes, the circulating medium is completely isolated from the outside world. Because the circulating medium being cooled is isolated from the outside world, completely closed, sometimes called evaporative condenser. Internal circulating medium, only cooling, no consumption without evaporation. As the heat exchanger tube outside the spray water vaporization, a large amount of water vapor and air mixing, humidity increases, by the axial fan, these saturated, high humidity, high enthalpy air out of the tower in the environment.
An evaporative condenser is a common, informal term for a closed-circuit cooling tower. In fact, it is precisely a closed-circuit cooling tower: it uses the evaporation of sprayed water, carried away by air outside the tower, to cool and exchange heat with the circulating medium inside the heat-exchange tubes. The circulating medium remains completely isolated from the external environment. Because the circulating medium being cooled is entirely sealed off from the outside world, it is sometimes referred to as an evaporative condenser. The internal circulating medium is only cooled—there is no consumption or evaporation. After the spray water on the exterior of the heat-exchange tubes vaporizes, a large amount of water vapor mixes with the air, increasing the humidity. An axial-flow fan then draws this saturated, high-humidity, high-enthalpy air out of the tower and into the surrounding environment.
