Human response to individually controlled micro environment generated with localized chilled beam

Type: conference-paper
Abstract: Indoor environment in a single-office room created by a localised chilled beam with individual control of the primary air flow was studied.Response of 24 human subjects when exposed to the environment generated by the chilled beam was collected via questionnaires under a 2-hour exposure including different work tasks at three locations in the room.Response of the subjects to the environment generated with a chilled ceiling combined with mixing air distribution was used for comparison.The air temperature in the room was kept at 26 or 28 °C.Results show no significant difference in the overall and local thermal sensation reported by the subjects with the two systems.Both systems were equally acceptable.At 26°C the individual control of the localised chilled beam lead to higher acceptability of the work environment.At 28°C the acceptability decreased with the two systems.It was not acceptable with the localized chilled beam.
