How does lowering the condenser water flow rate affect the condenser water t at a constant load?
Pump power goes down. Chiller power rises (as flow rate goes down, leaving condenser water temperature rises). Initially, cooling tower heat exchange effectiveness gets better, since the cooling tower receives warmer water. However, as flow is reduced further, heat exchange effectiveness is reduced.
What results when you reduce water flow to a water-cooled condenser?
Reduced water flow through a water-cooled condenser causes both the head pressure and condenser saturation temperature to rise. This is due to the condensers decreased ability to dissipate heat effectively, necessitating higher pressure and temperature for refrigerant condensation.
What effect will turning up the water mass flow rate in the condenser on the lab refrigeration apparatus have?
Work done by condenser will increase as the mass flow rate is increased hence the COP increases with flow rate.
What happens if condenser water temperature is too high?
The higher the condenser outlet water temperature, the higher the condenser pressure; we know that the condenser is a container and has a certain safety design range, so the unit will set a safety protection value to protect the condenser. Once this safety margin is exceeded value, the unit will alarm and shut down.
What is the flow rate of condenser water?
It is common for Engineers to estimate the Chilled Water and Condenser Water Flowrate based on their tonnage, as 2.4 usgpm/tonne for Chilled Water, and for Condenser Water, 3 usgpm/tonne.

What is condenser water reset?
Condenser water reset is a control strategy that will optimize chiller performance. This type of strategy is only applicable to water-cooled compressors.
What would be the best way to control condenser supply water temperature?
Cooling tower fans operate via on/off controls or modulate via variable frequency drives to maintain a condenser water supply temperature. VFDs provide the most energy efficient method of controlling the fans.
