We conducted research on the development of cooling tower cooling technology and the trend of wet bulb temperature in Guiyang throughout the year. According to the results, we found that the cumulative number of hours in which the wet bulb temperature of Guiyang was ≤14°C totaled 4327 hours, which accounted for 49.39% of the total. On the one hand, in winter, when the wet bulb temperature is 14°C as the switching temperature, the theoretical cooling hours in winter is 2130 hours. On the other hand, in spring and autumn, the theoretical hours of indirect cooling tower “free” cooling totaled 1904 hours. At the same time, it is worth mentioning that in winter and transitional seasons, the theoretical cooling hours account for 94% of the total free cooling hours available for cooling towers throughout the year. Through further analysis, we believe that the application of this technology in Guiyang has good energy-saving potential and application value. It should be noted that in actual engineering applications, the utilization characteristics of natural cold sources also need to be considered. At the same time, we have to combine the terminal form of the air conditioner and the characteristics of the cooling load to give full play to the energy-saving potential of cooling tower cooling technology.
