“…Phase change material (PCM) has been a better choice as an effective latent heat storage material, since it can provide thermal comfort by absorbing excess heat by nesting or releasing large amounts of energy in the form of latent heat during solid-liquid conversion [ [36] , [37] , [38] ]. PCM can be incorporated into cooling clothing to lower body temperature and achieve thermal comfort by absorbing thermal energy [ [39] , [40] , [41] ]. Therefore, the cooling clothing integrating with PCM (PCM-CC) can regulate fluctuations in body temperature as an option to improve thermal comfort for workers without temperature regulating devices [ 42 ].…”

As a cooling device for cooling the human body, the cooling garment has been used in many fields. This study was guided by the theory of traditional Chinese medicine (TCM), an acupoints-meridians cooling vest (AMCV) system was designed to cold and stimulate the acupoints and meridians of the human body. Three healthy male subjects were recruited to participate in the test (with AMCV or without AMCV, CON) in a high-temperature environment (37 ? 1?, 46 ? 3% RH) to simulate standing on duty for 50 minutes. The results showed that the skin temperature (Tskin) with AMCV was lower than that with CON (p < 0.05). The average Tskin with AMCV decreased by 0.45 ? more than that with CON (p < 0.05). The average tympanic temperature (Tty) with AMCV was lower than that with CON (p < 0.05). However, the average Tty with AMCV decreased by 0.05 ? more than that with CON (p < 0.05). The heart rate (HR) with AMCV was significantly lower than that with CON (p < 0.05). The average thermal sensation (TS) and thermal comfort (TC) with AMCV were better than those with CON in the corresponding period (p < 0.05). The results indicated that AMCV could improve thermal comfort and reduce the heat strain of the human body in a high-temperature environment.

“…PCS is always attached to clothing ensembles or chairs to have good contact with the human body. Depending on the cooling medium, the commonly used cooling technology includes air cooling, liquid cooling, and phase change material (PCM) cooling [6]. Air cooling, which forms air ventilation in the microenvironment underneath clothing, is great in taking away heat from the human body through thermal convection and evaporation [5,7].…”

Wearing a liquid cooling garment (LCG) that offers near-zone cooling improves the thermal comfort of pilots working in hot environments. Four LCG samples with different arrangements of tubes for distributing liquid were developed. Based on the analysis of the overall and local cooling efficiency of the four LCG samples using manikin tests, another novel LCG with a horizontal-vertical combined tube was proposed to achieve optimal cooling performance. Human trials were conducted to check the novel LCG for improving the thermal comfort of pilots in a hot indoor environment (40°C, 40% RH). The mean skin temperature of the subjects wearing the novel LCG was reduced by 1.9°C in the 120-minute-duration flying simulation work compared to the no-cooling scenario, and the greatest decrease in skin temperature (i.e., 5.7°C) was exhibited at the back waist. The thermal sensation at the upper body was improved to nearly neutral, and the heat stress level was reduced from moderate to slightly. The findings provide a guideline for designing personal LCG, thus benefiting the comfort and safety of pilots in hot cockpits.
