Experimental test and analysis of regional practicability of evaporative cooling technology

According to the characteristics of climate variability all over the country, establishes the six-district model with the evaporative cooling technology suited to different regions. Analyses the application modes of direct evaporation and indirect evaporation technology in different regions. Builds the test bed of the evaporative cooling air conditioning which can simulate the outdoor environment in different regions for the experimental measurements and compares with the theory studying. The results show that the application form of the evaporative cooling technology in six-district is broadly consistent with the theory; that the measured value of the air temperature is lower than the theory value and the cooling effect is better; and that it can meet the requirements of air conditioning supply air with the direct evaporative cooling when the outdoor design wet-bulb temperature for summer air conditioning is below 16 ℃.
