Spray water is transported by a water pump from the collection tank to the spray pipe at the top of the evaporative condenser. It is sprayed through a nozzle onto the outer surface of the condenser discharge pipe, forming a thin water film. Part of the water in the film absorbs heat and evaporates into steam, while the rest falls into the collection tank and is recycled by the water supply pump.
The axial flow fan forces air to be sucked in and flow through the coil from the top and lower side walls, while the packing and saturated hot and humid air are discharged into the surrounding atmosphere. Part of the water droplets carried by the hot and humid air are intercepted by the water collector, effectively controlling the loss of water droplets and causing water vapor in the atmosphere to be replenished with cooling water through the floating ball valve control in the system.
