Cooling Tower Tank Size

This will give you the tons of cooling required at 50 fleaving water temperature.

Cooling tower tank size.

Towers that hold a lot of water. Drift loss 0 02 water supply for new development in eliminator design blowdown. Calculate the total lbs hour of material your machine uses and divide it by the lbs ton listed below for your specific process. Water make up requirements of cooling towers.

Drift is entrained water in the tower discharge vapors. 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. 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. Basic cooling tower equipment. It can be as low as 0 01 of circulation flow if the cooling tower has windage drift eliminators. Cooling tons x 6 minimum tank volume.

Flow rate in gpm. Approximately 1 000 btu s are required to evaporate 12 gallons of water. It is important to have some excess flow in the pump and tower design for these situations. 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. To size your production machine cooling load use the following information. Tanks are structurally supported around top and sides as required. Plants commonly operate over the design capacity which means the cooling tower needs to keep up.

Watch for these special circumstances that may require special tank sizing. 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 is entrained water in the tower discharge vapor.

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. 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. Heat load btu hr gpm x 500 x.

Determining a cooling tower type and understanding some of the key design considerations will get you headed in the right. Tank cover manufactured from stainless steel and supplied in sections for ease of removal and access covers are optional. Towers that are located a long way from the tank. The following design data is required to select cooling towers.
