Evaporative condenser operation principle
Evaporative condenser operation principle
Heng An Series Evaporative Condenser uses water and air as cooling medium. The cooling medium exchanges the heat with high-heat gaseous refrigerant medium and hence the refrigerant medium becomes liquid. Inside, there are water dispatching system, condensing coils, wet padding heat exchange layer, and dehydrator and so on. Outside, there are water circulating pump, an electronic water-curing device and a propeller fan on the top of condensing coil.
The propeller fan strengthens the flow of the air and causes negative pressure inside. When the condenser works, the cooling water is sprayed from water dispatching system to the surface of condensing coils equably to form a thin layer of water film. The high-heat steam of refrigerant medium enters from the top of condensing coil and then the cooled liquid refrigerant medium is discharged from the bottom of the condensing coil. During this process, high-heat refrigerant medium exchanges the heat with the water and air outside the coil and increases the efficiency of medium exchange with the help of wind.
After absorbing the heat of refrigerant medium, some water turns into steam and is discharged by propeller fan. Meanwhile, the moisture in the air is collected by dehydrator to collecting basin, and then the non-gasified cooling water flows into heat exchange layer and its heat is taken away by the airflow. The cooled water converges in the basin to be used circularly by the pump later. In addition, there is a ball cock in the basin. When the water is consumed to a certain point, the ball cock will automatically open to replenish the cooling water
