The high-temperature gaseous refrigerant inside the evaporative condenser coil exchanges heat with the spray water and air outside the coil, and the refrigerant inside the tube gradually condenses from gaseous to liquid. The super strong wind force of the induced draft fan completely covers the surface of the coil with sprayed water, and the heat transfer effect is significantly improved by the water taking advantage of the wind force. The installation of the HL type two side coil middle fan has better heat transfer efficiency.
