| Abstract: | Environmental control of agricultural buildings by cooling technique of water evaporation is widely used in summer. In general, spraying water is not completely evaporated and is recirculated. From the point of view of energy saving, it is suggested to control the amount of wetting water precisely and to make it just be entirely evaporated. To improve the cooling system, the characteristics of heat and mass transfer of a wet pad cooling device are studied under the circumstance of spraying water completely evaporated and the formulas for determining the volume of spraying water and proper parameters of the wet pad are derived. |
