Abstract:

Significance Cooling clothing incorporated with phase change materials (PCMs) can provide thermal protection to the human body in extreme hot environments. Due to the capability of PCMs absorbing or releasing heat through phase change, heat transfer process of PCM clothing calls for comprehensive understanding. The poor moisture permeability and low surface temperature of the PCMs would not only impede water vapor transmission to the environment, but also increase the risk of moisture condensation, which makes the construction of heat and moisture transfer model of PCM clothing more complicated than that of ordinary clothing. Based on the analysis of the heat and moisture transfer mode and path in PCM clothing, the development process, characteristics and deficiencies of current heat and moisture transfer model were reviewed in this paper. The application status of heat and moisture transfer model in the development and performance optimization of PCM clothing was also discussed.

Progress At present, the development process of the model construction of PCM clothing was mainly divided into three stages (Tab. 1). In the first stage, the heat transfer model of the fabric-PCM was established with the enthalpy method. However, it was different from the actual heat transfer process because it neglected the effect of moisture transfer on energy conversion. In the second stage, the coupled heat and moisture transfer model of the fabric-PCM was established with the apparent heat capacity method, which considered the phase change during moisture transfer and its influence on energy conversion. In the third stage, the more complex coupled heat and moisture transfer model was established by using some optimized methods. For example, adding the solid desiccant layer onto the inner surface of PCMs to maintain dry cool microclimate air, placing the insulation layer onto the outer surface of PCMs to reduce the heat absorption from the hot environment, and adding the ventilation fan to enhance sweat evaporation. In addition, the established model was used for parametric study to provide suggestions for the development and performance optimization of PCM clothing. In the selection of PCMs, it was proposed to adjust the melting temperature, weight and distribution of PCMs according to the ambient temperature, working time and human physiological characteristics. When designing the working mode of ventilation fans, it was necessary to set the running time point of ventilation fans according to the human activity level or sweat production.

Conclusion and Prospect Although the model construction of PCM clothing has been developed from the heat transfer model to the coupled heat and moisture transfer model, problems exist. Firstly, existing models simplifies the air ventilation by fans as the air exchange between the clothing microclimate layer and the environment, and the air velocity and air layer thickness of each segment are regarded as uniformly distributed, so the influence of air ventilation on heat transfer is ignored. Then, due to the complexity of the radiative heat transfer process, existing models ignore or simplify the radiative heat transfer among human body, PCM clothing and environment. Besides, existing models regard the fabric as a porous medium with uniform thickness, and do not consider the influence of microcosmic factors such as fiber hygroscopic characteristics, yarn structure and the mixing ratio of each component in the cavities of the inner fabric layer on the thermal and humidity properties of PCM clothing. The future development trend is put forward as the multi-factor coupling of heat and moisture transfer, the dynamic simulation of air ventilation by fans, and the model construction changes from one dimension to multi-dimension and from macroscopic to microscopic.
