Cooling Tower Makeup
Since the makeup water typically contains dissolved solids these solids are typically left behind in the sump water as the water evaporates in the cooling tower.
Cooling tower makeup. Spx cooling technologies inc. Not less than 3 5 cycles of concentration is required for air conditioning cooling tower makeup water having a total hardness equal to or exceeding 11 gr gal 188 mg l expressed as calcium carbonate. Is a leading global manufacturer of cooling towers evaporative fluid coolers evaporative condensers and air cooled heat exchangers. There are two basic make up water strat.
Perry s chemical engineers handbook. Approximately 1 000 btu s are required to evaporate 12 gallons of water. Water make up requirements of cooling towers. Cooling tower makeup water calculate the amount of makeup water required for a cooling tower with following conditions.
Makeup water or the water replacing bleed and evaporated and leaked water from the cooling tower is first drawn from its source which could be raw water city water city treated effluent in plant wastewater recycle well water or any other surface water source. Blowdown cooling tower cooling tower makeup cooling tower makeup water drift loss evaporative loss. For nearly a century we have provided exceptional quality equipment and service to the hvac process cooling industrial and refrigeration markets. Meanwhile since the cooling water is a very effective air scrubber dust and debris present in the up flowing air is washed out by down pouring water and collects in the sump.
Control of the water level in the cooling tower basin is via a level instrument of some description. Natural gas line sizing using general pressure drop equation. Cooling tower mass balance gives an indication about make up water requirement in system. Cooling tower makeup water intake.
Cooling tower makeup is required due to water losses resulting from drift evaporation blowdown. Cycles of concentration. This is necessary to maintain the condenser water volume and keep dissolved minerals sufficiently diluted. Every cooling tower design requires a strategy for supplying make up water to replace water that is lost due to evaporation drift or blowdown.
Cooling tower makeup water 127 5 2 29 87 159 37 gpm. This should be located in the relatively still waters of the pump basin. Leave a reply cancel reply. Air conditioning cooling tower makeup water having discharge conductivity range not less than 7 gr gal.
Evaporative cooling towers like the advantage power tower series provide cooling by evaporating a small amount of the recirculated process water flow.
