Remember cooling tower water is full of air so air in the piping is a given.
Cooling tower condenser water pump.
The cooling tower is usually located up on the roof and is the final destination for the unwanted heat in the building.
The condenser water pump is used to circulate condenser water either in an open or a closed circuit system.
You just have to make sure to avoid any sudden pressure drops between the tower and the pump suction otherwise the air could pop out of the water enter the pump and destroy a pump shaft.
However the condenser water pump is running at 100 because the tower must not be allowed to dry up if elevated nozzle cups are installed the chiller can reduce its condenser water pump speed to 30 provided no low flow switches are tripped and the media will remain wetted.
Piping condenser cooling tower losses and.
This guide covers the design and selection of a condenser water pump.
Manufactures open loop cooling towers and closed loop cooling towers at its facility in north texas facility in burkburnett tx.
The cooling tower contains a large fan which blows air through the unit.
It must also provide the energy head necessary to raise water from a low to a higher static head.
The condenser water is pumped up to the cooling towers and it is sprayed into the air stream.
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.
Equalization the process whereby multiple cooling tower basins are mechanically connected through a piping system to allow for correction in the water basin level occurs.
This helps keep the operational cost of our chiller down.
The chiller is loaded to 30 and the cooling tower fan is off.
Given this cycle it follows that the lower the condenser water temperature that which is circulating to the cooling towers is the less work the compressor has to do.
The condenser water pump is a part of an overall condenser water system that often includes a chiller piping valves fittings water treatment and a cooling tower.
Location of cooling towers.
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.
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.
Open piping circuit for the tower piping circuit the pump must overcome the piping flow friction loss.
How the cooling tower impacts the efficiency of refrigeration cycle.
Furthermore whaley designs and builds cooling tower pump tank systems and chilled water pump tanks.
