Tanks are structurally supported around top and sides as required.
Cooling tower tank size.
It is both the theoretical limit to the exiting cooled water temperature and the only specific air parameter necessary in cooling tower selection.
Blowdown is a portion of circulating water that is discharged in order to lower solids concentration due to evaporative cooling.
Flow rate in gpm.
Cooling tower pump recirculation pump process pump stand by pump.
Heat load btu hr gpm x 500 x.
Drift loss varies between 0 1 and 0 2 of circulation flow.
Basic cooling tower equipment.
Cooling tons x 6 minimum tank volume.
This will give you the tons of cooling required at 50 fleaving water temperature.
When operating below 50 f you must decrease the rated chiller cooling capacity by 2 for every one.
Tank cover manufactured from stainless steel and supplied in sections for ease of removal and access covers are optional.
All tanks have baffled compartments if required.
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.
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.
It is important to have some excess flow in the pump and tower design for these situations.
Water make up requirements of cooling towers.
Calculate the total lbs hour of material your machine uses and divide it by the lbs ton listed below for your specific process.
Drift is entrained water in the tower discharge vapors.
To size your production machine cooling load use the following information.
Towers that hold a lot of water.
Drift loss in cooling tower is a function of drift eliminator design.
Evaporative cooling towers like the advantage power tower series provide cooling by evaporating a small amount of the recirculated process water flow.
Drift loss 0 02 water supply for new development in eliminator design blowdown.
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.
Plants commonly operate over the design capacity which means the cooling tower needs to keep up.
Towers that are located a long way from the tank.
Cooling tower sizing program.
Range of cooling in f t1 t2 area wet bulb temperature in f twb the design heat load is determined by the flow rate and the range of cooling and is calculated using the following formula.
It can be as low as 0 01 of circulation flow if the cooling tower has windage drift eliminators.
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature.
Determining a cooling tower type and understanding some of the key design considerations will get you headed in the right.
The following design data is required to select cooling towers.
