| Summary: | Effects of airflow rate and supply air temperature on the airflow pattern for Active Chilled Beams (ACB) system are investigated in this paper. The air velocity for the air jet near the ceiling are tested and recorded under both isothermal and non-isothermal conditions. The self-similarity for the air jet is observed to be feasible for a certain downstream distance where the vertical maximum velocity is within 1.25 slot heights. A comparison study has been conducted for two mathematical models describing the self-similarity with the experimental data. It turns out that Verhoff’s model has an overall better performance than Schwarz and Cosart’s model. |
