Abstract:

According to the meteorological parameters of Guizhou Province and the feasibility of developing cooling tower cooling in 4 typical cities and towns in thermal engineering districts, we found the following situation. First of all, if calculated according to the accumulated hours of 8,760 hours of wet bulb temperature below 14°C (including 14°C), Guiyang City (moderate area) has a total of 4327 hours, accounting for 49.39% of the total. Zunyi City (a region with hot summer and cold winter) has a total of 4469 hours, accounting for 51.02% of the whole year. For areas with hot summer and warm winter, such as Xingyi City (a hot winter and warm area), a total of 4404 hours, accounting for 50.27% of the whole year. Weining County (an area with cool summer and cold winter) has a total of 6792 hours, accounting for 77.53% of the total. In addition, if it is in winter (December, January and February), when the wet bulb temperature is 14°c, the cooling hours for Guiyang, Xingyi, Zunyi and Weining are 2152h, 2159h, 2130h, 2160h, which accounting for 97.46%, 99.95%, 98.61% and 100% of the cooling hours in winter. With the help of the above data, we can find that, first of all, these cities have little difference in the number of cooling hours in different climate zones in winter, and they all have the possibility of adopting cooling tower cooling technology. Secondly, in the transitional season, when the wet bulb temperature is 14°c as the switching temperature, the cooling hours of Guiyang, Xingyi, Zunyi and Weining are 2175h, 2232h, 2339h, 3858h, respectively. It can be said that these cities have the possibility of adopting cooling tower cooling technology. It is worth mentioning that in the transitional season, the cool summer and cold winter areas represented by Weining have more obvious advantages in climate and energy saving using cooling tower cooling technology.
