Synchronous solving model and key parameters for nozzle air supply in large space buildings

Cai Ning;Cheng Dandan;Wang Tianyi;Huang Chen;Wang Xin;Nanjing Institute of Technology;  
Develops a synchronous solving model for indoor air temperature and inner wall temperature under different conditions of nozzle air supply in large space buildings,and discusses the key parameters such as floor temperature and zone heat transfer coefficient.Establishes a heat balance equation of floor heat transfer considing the heat transfer from floor to underground soil,and corrects the zone heat transfer coefficient based on the air supply rate and the entrainment rate.Through an experiment on the thermal environment in a large space building in summer,tests indoor air vertical temperature and inner wall temperature,and verifies and improves the corrective synchronous solving model.The results show that the results of the corrective model agree well the test data.
