Abstract: During transitional season, the single tent is widely used for its features of being simple and easy to carry.Because of using poor heat insulation material as the tarpaulin of the tent, its thermal environment indoor is very bad.Experiment studies on improving the thermal environment in tents by using natural ventilation during transitional season at Tianjin were done. The thermal environment parameters of tents with different natural ventilation plans were recorded and analyzed. The experiment results show that natural ventilation plays a certain role in adjusting thermal environment of tents.

Key words: tent, natural ventilation, transitional season, thermal environment
