| Abstract: | A new type of air diffusion outlet with annular slot used for spot cooling air supplyis studied, in which the airflow pattern of this outlet and the regression formulas for airvelocity and temperature decay both the vertical airflow and the horizontal airflow aregiven. Based on the experimental data of human thermal sensation tested in a proper testroom, a comfort chart is put forward to provide for the spot air-conditioning with hori-zontal air supply, in which the parameters of spot cooling air supply can be determined. |
