The heating effect of phase change material (PCM) vests on a thermal manikin in a subzero environment

Summary, in English

The heating effects of three PCM vests (Tmelt=32, 28 and 24 °C) were tested on a thermal manikin with constant temperature at 30 ºC in a subzero environment (Ta=-4 °C, Va=0.4 m/s). The results showed that the heating effects lasted about 3-4 hours. The highest heating effects reduced heat loss for 20-30 W/m2 on the torso during the first two hours. The results also showed that the vest with higher melting/solidifying temperature had a greater and longer heating effect. Among the three wear scenarios, the PCM vest worn directly and closely over the stretch coverall without winter jacket revealed the highest heating effect on the torso.
