【Abstract】 Under the impinging jet ventilation system of cooling, the influences of the air supply parameters on the characteristics of the thermal environment and the energy consumption in the inner zones of the large space office buildings were numerically simulated. The effects and correlations of the changes of the airflow parameters of the impinging jet on the thermal stratification, draft sensation and energy-using efficiency are analyzed in detail. The reference range of the air supply parameters considering the thermal comfort and energy saving requirements is given.更多还原
