Abstract

Abstract: Introduced the design process of the semi-central evaporative cooling air conditioning system in an office building of Xinjiang,combined with the office building structure adopted tandem air -water system.Test results show that the outdoor dry bulb temperature is 35.0℃,and the tertiary evaporative cooling air unit can make the supply air temperature to 13.5℃.The water temperature of indirect-direct evaporative cooling composite chiller is 16.5℃,the indoor maintain in the air conditioning specification requirements of the comfort zone.The paper analyzes the semi-central evaporative cooling air conditioning system’s advantages and disadvantages,and provides some suggestions for evaporative cooling air conditioning system design.
