Cooling Tower Pump Sizing

We can help you size your pump based on your requirements.

Cooling tower pump sizing.

Furthermore whaley designs and builds cooling tower pump tank systems and chilled water pump tanks. 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. Include a fouling factor on pipes when sizing your pump. Heat load btu hr gpm x 500 x.

Keep in mind that you need the pump to develop enough pressure to get water to the highest and farthest places in the plant. The required cooling tower design and size will be a function of following values. Size the pump discharge piping per ashrae 90 1 2010 design tables. C approach to wet bulb temperature d mass flowrate of water circulation rate.

In order to understand how these factors influence cooling tower size it is first necessary to give the terms some context. Cooling tower sizing program. 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. If you don t size the pressure drop right it won t get there.

The following design data is required to select cooling towers. B web bulb temperature. Piping condenser cooling tower losses and valves. Heat load range approach and wet bulb temperature.

Remember ashrae now assigns a maximum pipe size on cooling tower condenser water systems. Wpi can provide you with a pump to supply you process or application. Flow rate in gpm. Pumps are typically sized for 65 feet of head.

For the tower piping circuit the pump must overcome the piping flow friction loss. Open systems like cooling towers get dirty so some degree of increased pressure drop is bound to occur with time. Flow feet of rise run line loss pressure loss in process equipment and pressure loss in any utilized integrated. 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.
