Countercurrent type closed cooling tower (also called evaporative type air cooler or closed cooling tower) is the tube type heat exchanger placed in the tower, through the heat exchange of circulating air, spray water and circulating water to ensure the cooling effect. Because of the closed cycle, it can ensure that the water quality is not polluted, well protect the efficient operation of the main equipment, improve the service life. When the temperature outside is low, you can stop the spray water system to save water. With the implementation of the national policy of energy conservation and emission reduction and the increasing shortage of water resources, closed cooling towers have been widely used in iron and steel metallurgy, power electronics, mechanical processing, air conditioning system and other industries in recent years.
Countercurrent cooling tower: compact structure, small model, can be placed in the workshop; Applicable standard temperature drop cooling project (5℃ temperature drop)
Operation principle of countercurrent type closed cooling tower:
1. Internal circulation: circulating water enters the table cooler after heat transfer and heating up, and the heat is sent to the outside world through the table cooler. After cooling, circulating water is sent to the heat source by the pump.
2, external circulation: the spray water is sent to the spray system by the tank, the water is ejected and the surface cooler contact for heat exchange, part of the hot steam is discharged by the fan, and the cooled spray water falls to the tank for circulation again.
Countercurrent type closed cooling tower features:
1, compact structure: countercurrent tower compared with the form of cross flow, the product structure is more compact, there are more coil cooling area layout, more suitable for cooling projects with small temperature difference.
2, the whole system: because the cooling tower occupies a small ground, with the circulating water pump, can be made into an integrated machine, easy to move.
3, the scope of use: because the tower body is compact, can be placed in the workshop, so the intermediate frequency power cooling, mechanical water jacket cooling is more suitable; It is especially suitable for projects with small temperature difference, such as the cooling of water source heat pump unit group.
Countercurrent type closed cooling tower advantages:
1. Stability: The circulating water of the closed cooling tower usually adopts soft water closed-circuit circulation, which effectively prevents the damage to the equipment caused by scale generated in the tower or the user's equipment during long-term use.
2. Water saving: Compared with the traditional cooling tower, the closed cooling tower is more suitable for use in areas where water resources are scarce because it adopts fully closed inner circulation and efficient dewatering device.
3. Energy saving: The closed cooling tower can control the starting number of the fan according to the temperature, and the spray pump can be opened and closed, and the regulating valve can also be installed to control the flow.
4, environmental protection: closed cooling tower through the fully closed inner road circulating water is not polluted, sustainable use. Spray water relative evaporation less, the maximum protection of the environment.
5, longer service life: our company uses high-quality metal materials, greatly improve the ability to use and maintain the proper life is usually more than 10 years, late maintenance and low cost.
