ABSTRACT:
An open recirculating evaporative cooling system includes a cooling tower or evaporative condenser (12) having a heated water inlet (20) and a water collection basin (22), a water supply (34) for supplying a volume of water to the cooling tower, a water supply meter (36) coupled between the cooling tower and the water supply, for registering the volume of water supplied to the cooling tower from the water supply and for providing pulse information corresponding to the volume of water supplied, a heat exchanger (16) coupled to the cooling tower basin for receiving water therefrom, for removing waste heat (18) from heat producing equipment, and for supplying the heated basin water to the cooling tower heated water inlet, a solenoid valve (30) coupled between the heat exchanger and a drain for draining water from the cooling tower basin through the heat exchanger, sources of water treatment (24, 26, 28) coupled to the cooling tower for supplying corrosion and scale and biological fouling controlling additives thereto, and a microprocessor controller (38) connected to the water supply meter, the drain valve and the water treatment sources for receiving the pulse information from the water meter in terms of volume (gallons, liters, etc.) per pulse, and for controlling both the water treatment sources for the supply of the corrosion and scale and biological controlling additives to the cooling tower and the draining valve for draining water from the cooling tower basin.
