Notes on purchasing air coolers 1. Equipment selection control parameters for it material, working pressure, design temperature, etc. 2. When choosing the equipment, should try to make the side of the heat transfer coefficient is small to get a large flow rate, and try to make the heat transfer coefficient of both sides of the two fluid heat transfer surface equal or similar, rising heat transfer coefficient. The temperature of the fluid heated by the air cooler should be 10 ℃ lower than the saturation temperature under its export pressure, and should be lower than the working temperature of the pump used for secondary water.
