摘要：The aim of this study was to analyze the heat transform models of phase change diving suit on the basis of the steady-heat transform theory, and determined the suitable melting temperature and latent heat of phase change materials impregnated in different suits. An insulation performance test was conducted to compare the PCM-enhanced diving suit with the conventional one. The results showed that the best melting temperature of PCMs should range from 29.2 to 35.7(o)C in the model 1, while it could range from 24.9 to 31.4(o)C in the model 2. If the water temperatures showed 0, 5, 10 and 15(o)C, according to the model 2, the required mass of PCM-1 in a thermal-enhanced diving suit were 0.9-2.5, 0-1.3, 0-0.04 and 0 kg, respectively; the corresponding values of PCM-2 were 1.0-2.8, 0-1.5, 0-0.05 and 0 kg, respectively. From the application performance test, the insulation time last for 61 min at 25 C-o, and 83 min at 20 C-o for the conventional diving suit. While it last for about 68 min at 25 C-o, and 98 min at 20 C-o for the thermal-enhanced diving suit with PCM-2; and it last for about 81 min at 25 C-o, and 116 min at 20(o)C for thermal-enhanced diving suit with PCM-1. All demonstrates the effectiveness of the PCMs used in the garments on improving thermal protection in the cold exposure.
