Cooling tower can be divided into closed cooling tower and open cooling tower according to whether water and air are in direct contact. In addition to considering the investment cost, an analysis and comparison should be made on the performance of the two cooling towers.

01. Open cooling tower

The cooling principle is that the circulating water is sprayed onto the filler of glass fiber by spray method, and the heat exchange is achieved through the contact of water and air, and then a fan drives the air circulation in the tower to bring out the hot gas flow after heat exchange with water, so as to achieve cooling. This cooling method has less investment in the first phase, but higher operating costs (water consumption, power consumption).
