| Abstract: | The characteristic of the air flow and heat distribution in air conditionedrooms with horizontal displacement air supply system placed in the occupiedzone has been studied in this paper. By the way of theoretical analysis withmodel test, the influence of performance between the horizontal supplied co1dair jet and the natural convective heat jet from the heat source was discussed.The optimum coordinatiye state of these two jets is proposed. Some main influ-ence factors affected the air flowage were found. An empiric formula for calcu-lating coefficient of heat distribution was proposed. |
