It can be as low as 0 01 of circulation flow if the cooling tower has windage drift eliminators.
Cooling tower tank size.
Cooling tower sizing program.
Heat load btu hr gpm x 500 x.
Tank cover manufactured from stainless steel and supplied in sections for ease of removal and access covers are optional.
Towers that hold a lot of water.
Tanks are structurally supported around top and sides as required.
The following design data is required to select cooling towers.
Plants commonly operate over the design capacity which means the cooling tower needs to keep up.
Approximately 1 000 btu s are required to evaporate 12 gallons of water.
Determining a cooling tower type and understanding some of the key design considerations will get you headed in the right.
Basic cooling tower equipment.
Towers that are located a long way from the tank.
When operating below 50 f you must decrease the rated chiller cooling capacity by 2 for every one.
Drift loss varies between 0 1 and 0 2 of circulation flow.
Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near.
Blowdown is a portion of circulating water that is discharged in order to lower solids concentration due to evaporative cooling.
This will give you the tons of cooling required at 50 fleaving water temperature.
Evaporative cooling towers like the advantage power tower series provide cooling by evaporating a small amount of the recirculated process water flow.
Calculate the total lbs hour of material your machine uses and divide it by the lbs ton listed below for your specific process.
Flow rate in gpm.
Drift loss in cooling tower is a function of drift eliminator design.
Drift is entrained water in the tower discharge vapor.
Or for high flow systems greater than 3 gpm ton select a tank size so that the water will reside in the tank for at least 1 minute.
Water make up requirements of cooling towers.
It is both the theoretical limit to the exiting cooled water temperature and the only specific air parameter necessary in cooling tower selection.
Cooling tower pump recirculation pump process pump stand by pump.
Drift is entrained water in the tower discharge vapors.
The wet bulb temperature wbt of the air entering the cooling tower is an independent variable that is a fundamental factor in dictating the appropriate size of a cooling tower.
Watch for these special circumstances that may require special tank sizing.
It is important to have some excess flow in the pump and tower design for these situations.
All tanks have baffled compartments if required.
