Use of local convective and radiant cooling at warm environment: effect on thermal comfort and perceived air quality

Year: 2012

Type: conference-paper

Abstract: The effect of four local cooling devices (convective, radiant and combined) on thermal comfort and perceived air quality reported by 24 subjects at 28 ˚C and 50% RH was studied.The devices studied were: (1) desk cooling fan, (2) personalized ventilation providing clean air, (3) two radiant panels and (4) two radiant panels with one panel equipped with small fans.A reference condition without cooling was tested as well.The response of the subjects to the exposed conditions was collected by computerized questionnaires.The cooling devices significantly (p<0,05) improved subjects' thermal comfort compared to without cooling.The acceptability of the thermal environment was similar for all cooling devices.The acceptability of air movement and PAQ increased when the local cooling methods were used.The best results were achieved with personalized ventilation and cooling fan.The improvement in PAQ when the radiant panel was used alone was minimal.
