1. Standard design conditions: dry bulb temperature 31.5 °C, wet bulb temperature 28 °C, atmospheric pressure 99400Pa, inlet water temperature 37 °C, effluent temperature 32 °C; 2. Select the special packing material of the oblique trapezoidal wave square tower, with excellent thermal performance and small ventilation resistance, so that the cooling tower can achieve the design purpose of compact structure and small footprint; 3. The counter-current square cooling tower adopts the airfoil-type fasting structure with large diameter, large area, low speed, low dynamic pressure FRP fan blade, and the use of this type of cooling tower has the remarkable characteristics of energy saving and low noise;
