Technical Description Of Counterflow Closed Cooling Towers

During the cooling process of a closed cooling tower, the cooling medium (soft water, oil or other liquid) is driven by the main circulating pump between the heat communicator and the equipment to be cooled. Spray water evenly on the heat communicator. The outer and outer surfaces of the heat communicator constitute an average water film. The cold air enters the tower through the air inlet under the main body of the tower, and the spray water flows to the lower part of the heat communicator. In this process, there are two heat communication methods, that is, the heat communication between the cold air and the cooling medium and the heat communication between the evaporation and heat absorption of the spray water. After receiving the heat, the full humid and hot atmosphere is discharged into the atmosphere through the electric fan. It is then transported to the spray system. In this way, the cooling medium in the heat exchanger is cooled. There are two ways of working in closed cooling towers. Air cooling, air cooling + spraying. The electronic control system automatically terminates the two switching methods according to the requirements of the operating conditions, ending energy saving and consumption reduction.
