Analyses energy saving effects of free cooling technique. According to the hourly data measured for 8 760 hours through a whole year in a city in Shandong, presents the frequency and accumulative frequency of air web-bulb temperature appearing in every interval. The result shows that there are 4 208 hours of wet-bulb temperature equal to or u...
