Air conditioning and ventilation system operation and field measurement of exhibition hall building in transitional seasons

Takes the natural ventilation operation strategy of A-1# exhibition hall building in the International Science and Technology Park of Suzhou in transitional seasons as an example, performs the theoretical analysis and field measurement. Presents the determination method of outdoor critical switching temperature. Taking the summer condition as an example, discusses the joint operation strategy of natural ventilation and air conditioning system when the outdoor air temperature is higher than upper limit of switching temperature.
