Condenser Pump Cooling Tower

At this point the refrigerant is in the form of a high pressure high temperature liquid.

Condenser pump cooling tower.

4 0 condenser water pump calculator inputs in order to best use the condenser water pump calculator you should have an understanding of. The cooling tower fans modulate in order to maintain the necessary condenser water supply temperature. Include a fouling factor on pipes when sizing your pump. Open systems like cooling towers get dirty so some degree of increased pressure drop is bound to occur with time.

Size the pump discharge piping per ashrae 90 1 2010 design tables. The condenser water leaves the condenser of the chiller at around 32 c 89 6 f and the pump sends this up to the cooling tower. Remember ashrae now assigns a maximum pipe size on cooling tower condenser water systems. For the tower piping circuit the pump must overcome the piping flow friction loss.

The system has been designed so that the condenser water leaving the cooling tower and re entering the chiller condenser must be around 27 c 80 6 f in order to be able to pickup enough heat on it s next cycle. The condenser wate r pumps run at a constant speed flow. It must also provide the energy head necessary to raise water from a low to a higher static head level. Cooling towers and condensers are heat exchanger devices but work in opposite directions.

This hot gas passes through condenser where it is cooled and condensed into a liquid giving up its btus via heat exchange with the cooling tower loop.
