Abstract
The purpose of the study was to investigate and compare the effect of two cooling garments with phase change

material (PCM) and ventilation on thermal comfort. Eight female university students (age 24±1 years; height 162±4 cm; body

weight 54±4 kg) exercised on a treadmill in an environment of 32 oC with 50 % relative humidity. Tests in three conditions

were carried out after moderate exercise with t-shirt and shorts: cooling with a PCM vest (PCM); cooling with a ventilation

jacket (VEN) and without cooling clothing (natural cooling, a control condition, CON). Results showed that no significant

differences were observed in the mean skin temperature and heart rate among the two cooling garment... (More)

jacket (VEN) and without cooling clothing (natural cooling, a control condition, CON). Results showed that no significant

differences were observed in the mean skin temperature and heart rate among the two cooling garment conditions and the

control condition (p>0.05). The local torso skin temperature was observed with significant difference among the three

conditions (p<0.05) and it was mostly reduced by 0.7 oC and 0.9 oC, respectively in PCM and VEN. Significant differences

were observed in the clothing torso micro-climate temperature and humidity among the three testing scenarios (p<0.05). The

clothing micro-climate temperature was dropped by 2 oC in PCM and 0.8 oC in VEN. The clothing micro-climate humidity in

PCM was 40 % higher than that in VEN after 30 minutes cooling. The perceived thermal sensation was the lowest in PCM

whereas the perceived skin wettedness sensation was the lowest in VEN. (Less)
