The spray pump circulates water from the reservoir at the bottom of the unit to the spray nozzles on the refrigerant coil. The fans force the passage of air through the serpentine and the water being sprayed onto the serpentine.
The heat from the refrigerant is transmitted through the walls of the coil to the water passing over it.
Air removes heat from the water by evaporating part of it. Droplet separators prevent droplets of water from being carried through the air.
They are selected based on a difference of 10 to 15 ° C, between the condensing temperature and the wet bulb temperature of the air entering the condenser.
• The water pump of these condensers is of lower capacity than that required by water cooled condensers.
• They should be located close to the compressors.
