Abstract

Basing the similarity theory, the scale effect model of the spraying water cooling system of according the prototype of the Gymnasium in University of Shanghai for Science and Technology was experimental studied in this research and the following conclusions could be drown: At summer sunny day in Shanghai which the solar radiation value of the experimental period were between 16.4-17.3 MJÂ·m-2. At roof exposing under the solar radiation condition, the maximum temperature of the outer roof was about 57.8Â¿. At roof under spraying water system, the maximum temperature of the outer roof was about 37.2Â¿. So the roof sprinkling system reduces the roof temperature obviously and it can save the air condition electric power load.
