The Summer Indoor Thermal Environment of Evaporative Cooling Air-conditioned Rooms in Public Buildings in Northern Xinjiang, China
Evaporative cooling air conditioning technology is becoming more and more popular in public buildings in hot and dry plateau areas in China. However, there are few studies on the indoor thermal environment problem caused by new technologies. In this study, field tests were conducted on the summer indoor thermal environment of public buildings in the northern Xinjiang area, China. The test results indicate that the indoor cooling effect of an evaporative cooling system attenuates more sharply along the direction of air supply than in the case of mechanical cooling, and the indoor thermal environment shows more significant variation. This study carries out simulations taking a public building model with a small bay width as the research object. Though simulation; with the bay width and net height of the room fixed, the depths of south- and north-facing rooms are changed in simulations of temperature changes under evaporative cooling air conditioning, and the results are compared with standard requirements for thermal comfort. Finally, the best architectural design form and parameter system for local public buildings using evaporative cooling air conditioning technology in summer is proposed, realizing the use of integrated design to promote the utilization of new renewable energy technology.
