Abstract

The response of 24 subjects to the local environment established by localized chilled beam combined with chilled ceiling (LCBCC) was studied and compared with response to the environment generated by mixing ventilation combined with chilled ceiling (CCMV) at two temperature conditions of 26°C and 28°C. The supply airflow rate from the LCBCC was controlled by the subjects within the range of 10 to 13 L/s. In the case of CCMV subjects did not have control over the flow rate. The results showed that occupants’ overall and local thermal sensation acceptability improved at the workstation by using the LCBCC system compared to CCMV. The subjects felt less warm with the LCBCC and their thermal sensation was close to neutral. Most of the subjects achieved acceptable air movement at the workstation by the provided individual control of the flow rate from the LCBCC. Need for air movement was reported in the case of CCMV.
