Correct operation method of cooling tower

Correct operation method of cooling tower

Although the cooling tower is an auxiliary equipment in the air-conditioning refrigeration system, it is responsible for the important task of dissipating the total heat absorbed by the entire system. Therefore, the correct operation of the cooling tower is directly related to the cooling effect and energy saving of the entire air-conditioning system. . Since the misoperation of the cooling tower mentioned above is relatively common, and the whole process from startup to shutdown exists, it is very harmful and should be paid great attention by relevant operators and managers.

The correct operation method and requirements of the cooling tower are:

(1) The number of cooling towers used matches the number of units opened.

(2) Close the inlet and outlet valves of cooling towers without fans to prevent cooling water from flowing through towers not in use.

(3) For the temporarily added cooling tower fan, after turning off the fan, do not forget to close the inlet and outlet valves of the tower.

(4) Check the operation of the cooling tower after starting each shift. It was found that cooling water passed through the cooling tower without fan. It is necessary to close the water inlet and outlet valves of the tower in time, and adjust the water level of the water tray to adjust the condenser, evaporator, and screw chiller of the air conditioning system. Some units are equipped with electric valves, but the electric valves are prone to failure and failure. Intensify checks to ensure that the system is functioning properly and properly The cooling process is actually a heat exchange process. The heat exchange of the chiller is more complicated than that of the window, split and cabinet air conditioners. The former is indirect refrigeration and the latter is direct refrigeration.
