Condenser Water Pump Cooling Tower

First and foremost ideally an open cooling tower should be located at the highest point of the condenser water system.

Condenser water pump cooling tower. The great thing about this configuration is that it allows you to mix and match pumps condensers and cooling towers so you have the maximum amount of stand by for virtually any situation. 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. Open piping circuit for the tower piping circuit the pump must overcome the piping flow friction loss. This will allow for adequate net positive suction head npsh for proper pump operation and minimize or eliminate potential hydraulic problems associated with open systems.

Correctly piping the suction and discharge of your cooling tower condenser water pump is critical. Some fairly catastrophic events can occur if either is improperly installed. Condenser water temperature cooling towers are generally selected to supply 85 f water to the chiller condenser at design conditions i e when th e ambient wet bulb temperature equals design and the chiller is operating at full load. But these conditions rarely occur.

The compressor pumps up the refrigerant into a high pressure high temperature state since temperature increases with pressure of any given refrigerant. This means that the operating parameters at which cooling towers are rated are based 3 gpm of condenser water entering the cooling tower at 95 f and leaving the cooling tower at 85 f under 78 f degree wet bulb conditions. Here are some best practices for piping cooling tower condenser water systems. Starting with the suction piping it is important to take precaution to avoid air pockets which can destroy a pump in pretty short order.

Water level pump suction water will reach this level without pump energy. Condenser water pumps that are located very close to the tower they serve are particularly prone to this if the tower outlet is undersized or the flow rate is higher than the tower is designed to accommodate because a vortex forms in the tower basin at the suction connection and entrains air into the piping leading to the pump. In this arrangement the pumps are manifolded together with one single pipe running to all three condensers and one pipe coming back from the cooling towers. Piping condenser cooling tower losses and.

Some fairly catastrophic events can occur if either is improperly installed. It must also provide the energy head necessary to raise water from a low to a higher static head level. Pump suction and discharge piping correctly piping the suction and discharge of your cooling tower condenser water pump is critical. It s a snapshot of a common operating design condition which puts all cooling towers on a comparable playing field.
