Load Conditions

The air conditioning system did not run as the design conditions in most of the time. Therefore, how to rationally adjust air parameters under part-load conditions caused by changes in the outdoor environment is an important issue, which is crucial to people’s comfort and energy systems. This paper introduces the part-load rate α to distinguish among different load-part conditions. And by taking the typical conditioned space of underfloor air distribution (UFAD) system in perimeter zone of New Tianjin Library as the object and using Fluent for simulation analysis, we get the conclusion that there is a maximum limit of supply air temperature and a minimum limit of supply air velocity under summer part-load conditions. For each condition, there is a set of optimal air parameters to make the indoor personnel achieve the most comfortable condition. Finally, we acquire this set of optimal air parameters by simulating and analyzing.
