Simulation and analysis of HVAC system for Tianjin Youyi Road International Finance Center

Considering the features of large north-south span and core tube structure of the building, simulates the natural room temperature using DeST-c software and analyses occurrence frequency of uneven thermal distribution in winter, offering a reference criterion for whether adopting more expensive four-pipe water system or not. Based on the analysis, recommends adopting natural ventilation to reduce the frequency of uneven thermal distribution.
