Individually controlled localized chilled beam with background radiant cooling system: Human subject testing

This study examines the responses of twenty-four subjects to an individually-controlled localized chilled beam (LCB) and compares it a mixing ventilation (MV) as reference system. Both LCB MV also used ceiling cooling (CC) panels for background (forming LCBCC MVCC systems). The directed supply air towards create micro-environment around them. Four experimental conditions were established using combination two room temperatures (26 °C 28 °C) primary rates (10 l/s 13 l/s). During 90 min-long experiments, asked assess their perceived quality, thermal sensation, comfort, movement acceptability work environment. results indicated that was superior with significantly higher environment, quality sensation. Perceived sensation rated near “clearly acceptable” level both when used. Moreover, votes close “neutral” high 26 °C. by found be resilient changes in temperature. With MVCC, environment “slightly warm”. No major potential risk draught among reported LCBCC. findings this contribute development high-temperature systems general, particular.
