Cooling tower tank design.

Cooling tower equipment louver motor pump tank. 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. Cooling towers may either use the evaporation of water to. Remote sump tanks can be added to cooling tower closed circuit cooling tower or evaporative condenser systems.

Design and operation 2005 2018 trane a business of ingersoll rand. For the tower piping circuit the pump must overcome the piping flow friction loss. Remote sump tanks are often installed indoors in a heated space to prevent freezing of the recirculating water during cold weather operation. B web bulb temperature.

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. Tanks are structurally supported around top and sides as required. Tank cover manufactured from stainless steel and supplied in sections for ease of removal and access covers are optional. The majority of our cooling tower sump tanks are sandblasted interior to a near white followed by 7 to 11 mils dft of epoxy.

It must also provide the energy head necessary to raise water from a low to a higher static head level. The required cooling tower design and size will be a function of following values. If the tank has a flat bottom the exterior bottom of the tank should have a commercial blast followed by a coal tar epoxy to protect from the condensation. Cooling tower pump recirculation pump process pump stand by pump.

All tanks have baffled compartments if required. D mass flowrate of water circulation rate e air velocity through tower or individual tower cell. I suggest that you review the sump design suggestions conatined in the pump handbook karrassic et al and the information in the hydraulic institute standards cooling tower pumps require an additional npsh margin above the npsh required. A trane engineers newsletter live cooling towers and condenser water systems.

If additional head pressure is a possibility the additional head pressure should be calculated and built into the design of the tank. Introduction a cooling tower is a heat rejection device which extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature. If the tank has a flat bottom the exterior bottom of the tank should have a.
