Principle of Operation

During the operation of the cooling tower, it mainly consists of two closed circulation systems:

1. Internal circulation: The hot water flows from the heat source into the cooling coil of the cooling tower through the circulating water pump. Under the action of the cooling tower, the water temperature is lowered and then flows back to the heat source equipment.

2. External circulation: driven by the spray pump, the spray water is sent from the bottom tank to the spray pipe at the top of the cooling tower, sprayed onto the heat exchange coil through the ABS sprinkler, and some of the hot steam is discharged through the fan. The spray water falls back to the bottom of the sink.

Warm water from the heat source is pumped into the heat exchange coils of the cooling tower. The water is distributed on the coil through the ABS nozzle. At the same time, air is drawn through the intake louvers at the bottom of the tower and up through the heat exchange coil opposite the water flow. Evaporate a small portion of the water and remove heat from the remaining water. Warm, humid air is drawn into the top of the cooling tower by a fan and discharged into the atmosphere. The cooling water is drained into the pool at the bottom of the tower and returned to the heat source.
