Heating performance of heating floor integrated with impinging jet ventilation system

Radiant floor heating systems provide comfortable indoor thermal environment. Primary air supply can be used to remove contaminants in the space heated by radiant floor. In this study, performance of integrated system impinging jet ventilation (IJV) and was numerically investigated. The lowest capacity 0 W/m 2 gradually increased 50W/m , primary temperature supplied IJV were 14, 16 18°C, respectively. terms contaminant removal efficiency, efficiency (CRE) applied. vertical dimensionless distribution analyse HF on air. numerical results showed that layer could 60% 80% under heat effect HF. same is true for low 14 °C. IJV/HF generated weaken stratification which beneficial energy saving. CRE influenced downward airflow external wall. Sufficient overcome downflow effectively increase value (> 2).
