Evaporative condenser - A heat exchanger in which refrigerant is condensed by a combination of air movement and water sprays

Working principle

high-temperature gaseous refrigerant in the coils transfers heat with air and spraying water outside it. The refrigerant is condensed from gas to liquid state gradually. Thanks to the powerful fan and special design of the coil, spraying water covers the surface of coils completely. The effectiveness of heat exchange is obvious. The temperature of spraying water and air rise after absorb heat. Partial water transfer to gas. Taking away vast amounts of heat. The water in hot air is prevented by baffle and is collected in PVC heat transferring layer. Those water is cooled by flowed air, and fall into collective groove. Then it is pumped into spraying system and circulate again. Lost water is supplied by water level regulator.

Running  Procedure

1) Hot gaseous refrigerant in the coil transfers heat to spray water and air outside the coil, being cooled into liquid.

2) The draught fan produces extra forced air that enables spray water to cover the coil surface thoroughly, thus resulting in remarkable improvement in heat-exchange performance.

3) While spray water and air absorbs heat, the water partly turns into vapor due to its increased temperature. Therefore, a great deal of heat is taken up by the latent heat of vaporization. Water out of the heated air is baffled to the PVC heat-exchange fill.

4) Cooled by air across the PVC heat-exchange fill to a lower temperature, water flows into the water sump where it is pumped to the spray system for repeating circulation.

5) A water level controller is designed to control the water makeup for water dispersed into surrounding air.

Application

The product is extensively applied to chemical industry,medicine, industrial refrigeration, beer, beverage and refrigeration.
