A novel dew point indirect evaporative cooling system was constructed and experiments were carried out to investigate the climate suitability in China(eight simulated climatic conditions).The results showed that when the primary air flow rate is 150m3/h,the Wet bulb efficiency ranged between 80%~99%and the dew point efficiency between 50%~75%,cooling capaci-ty between 0.27~0.71kW,The outlet air temperature and humidity can meet the thermal comfort needs of the people in Hohhot, Jiuquan and Urumqi.When the primary air flow rate is 1500m3/h,the Wet bulb efficiency ranged between 39%~47%and the dew point efficiency between 25%~32%,cooling capacity between 1.2~3.3kW,the outlet air emperature and humidity can not meet people''s thermal comfort needs.
