An improperly maintained cooling tower will produce warmer cooling water, resulting in a condenser temperature 5 to 10 degrees F higher than a properly maintained cooling tower. This reduces the efficiency of the chiller, wastes energy, and increases cost.

THE BASICS OF COOLING TOWER WATER TREATMENT

THE BASICS OF COOLING TOWER WATER TREATMENT

Cooling is accomplished through the latent heat of vaporization. For each pound (.121 gallons) of water that a cooling tower evaporates it removes about 1,000 BTU’s from the liquid that remains. As evaporation increases more heat is removed. Water vapor evaporates, leaving dissolved or suspended solids in the re-circulating cooling water.

For example, a cooling tower sized to cool 4540 m 3/hr through a 13.9C range might be larger than a cooling tower to cool 4540 m3/hr through 19.5C range. Range Range is determined not by the cooling tower, but by the process it is serving.

Nov 26, 2019 A chiller is a relatively basic system wherein heat is removed directly from the coolant before it’s transferred over to the surrounding air, which is essential for the cooling process. As for a cooling tower, this system is designed to remove heat from any water that’s discharged from the condenser unit.

Sizing Selecting - Cooling Towers

The first step in selecting a cooling tower is to determine the Nominal cooling tower load. Since a cooling tower ton is based on 15,000 BTU/Hr, the formula is: Nominal Load = GPM X 500 (Constant) X Range of co oling, 15,000 BTU/Hr/Ton . or, the more simplified version of the same formula, Nominal Load = GPM X Range of cooling 30

The thermal capability of a cooling tower used for air condition- ing is often expressed in nominal cooling tower tons. A nominal cooling tower ton is defined as cooling 3 gpm of water from 95F to 85F at a 78F entering air wet-bulb temperature. At these condi- tions, the cooling tower rejects 15,000 Btuih per nominal cooling tower ton.
