Product Description
Closed cooling tower (also called evaporative air cooler or closed cooling tower) is to place a tubular heat exchanger in the tower, and ensure the cooling effect through the heat exchange of circulating air, spray water and circulating water. Because it is a closed cycle, it can ensure that the water quality is not polluted, which protects the efficient operation of the main equipment and improves the service life. When the outside temperature is low, the sprinkler system can be stopped to save water. With the implementation of national energy conservation and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in industries such as iron and steel metallurgy, power electronics, machining, and air conditioning systems in recent years.
Principle:
1. Internal circulation: The circulating water enters the surface cooler after heat exchange by the heat source, and the heat is sent to the outside through the surface cooler, and the cooled circulating water is sent to the heat source by the water pump.
2. External circulation: The spray water is sent from the water tank to the spray system. After the water is sprayed out, it contacts the surface cooler for heat exchange. Part of the hot steam is discharged through the fan. The cooled spray water falls to the water tank and circulates again.
Advantages of closed air cooling:
1. Stability
2. Water saving
3. Energy saving
4. Environmental protection
5. Longer service life
