Closed type cooling tower is a tubular heat exchanger placed in the tower, through the circulation of air, spray water and circulating cooling water heat exchange to achieve cooling effect of a device. In recent years, closed cooling towers have been widely used in power electronics, mechanical processing, air conditioning system and other industri···

1) Add antifreeze in drainage and coil pipe (closed tower)1. Close the inlet and outlet valve of the inner circulating water pipe leading to the cooling tower;2. Close the circulating water refill valve in the cooling tower to cut off the automatic refill when the system pressure changes, affecting the normal drainage of the system. (refers to the ···

The popularity of closed cooling tower makes it used in various industries. With the improvement of function and technology, it will play a role in pressurized water reactor nuclear power plant in the future. Domestic pressurized water to nuclear power plants are generally divided into three circuits, so ordinary cooling equipment can not meet the ···
