Condenser Water Pump Function

The function of the condensate extraction pump is to extract the condensate from condenser and supply this to hot well at atmospheric pressure.

Condenser water pump function. However regular inspection of this unit is critical as you do not want to have to come back to your house with water dripping all over your carpet furnitures or electrical goods. Condensate pumps are used in hydronic systems that cannot discharge excess condensate water via a gravity feed. Once this happens the switch will turn off the pump. The condenser water pump is used to circulate condenser water either in an open or a closed circuit system.

There is a float in this tank that tells the condenser pump when to turn on and when to turn off. The liebig condenser is simply a straight tube within a cooling water jacket and is the simplest and relatively least expensive form of condenser. When there is enough water in the condensation tank the float is high enough the pump turns on. The condenser water pump circulates return condenser water from the chiller back to the cooling tower.

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. When the water reaches set level the float switch will turn on the pump until the water is drained from the tank. The cooling tower then cools the condenser water and the condenser water is supplied back to the chiller. It is designed to condense effectively the compressed refrigerant vapor.

The condensate pump that is used in residential system is usually low power approximately 60w and simple in function. Generally the condensate pump has the following specifications and functions that you should know. In a cooling cycle of a refrigeration system heat is absorbed by the vapor refrigerant in the evaporator followed by the compression of the refrigerant by the compressor. They are usually connected to a tank into which steam condenses into water.

They are used to remove condensate water from hvac systems that cannot be accomplished via gravity and therefore the water must be pumped up. Size the pump discharge piping per ashrae 90 1 2010 design tables. Open systems like cooling towers get dirty so some degree of increased pressure drop is bound to occur with time. Condensate pumps are usually electrically powered centrifugal pumps.

Include a fouling factor on pipes when sizing your pump. Float switch is used to energize the pump. The graham condenser is a spiral tube within a water jacket and the allihn condenser has a series of large and small constrictions on the inside tube each increasing the surface area upon which.
