Automatic control system of a cell-type cooling tower
The cooling tower is a device for cooling a large amount of water by directed air flow. Cooling towers are used in water recycling systems for cooling heat exchangers.
In mechanical-draft cooling tower the cooling process is going on due to evaporation of a part of water when its runoff by a cooling tower filler along which in the opposite direction of the water movement the flow of air is supplied. Evaporation of 1% water leads to decrease in the temperature of the remaining water mass to 5,48оС.
Automatic control system of a cell-type cooling tower is intended for the fan control using frequency converters.

Automatic control system of a cell-type cooling tower is intended for the fan control using frequency converters. Its use enables the control of the cooling process, which is achieved by precise regulation of the fan speed and thus the cooling water process. Additionally, the system monitors and alerts the operator of any malfunctions in the production equipment.
The system provides:
- stable predetermined cooling water temperature;
- safe operation of the cooling tower.
The economic effect from the implementation of ACS is achieved by reducing the annual electricity consumption more than 30%.
