摘要/Abstract

摘要：

为了优化设计人体睡眠系统,考虑了不同睡眠时期生理参数的差异性,建立并验证了睡眠状态下四节点体温调节模型,预测了核心温度和皮肤温度的变化,探讨了环境温度、被褥热阻及人体与被褥的接触面积3个因素对睡眠人体热舒适性的影响。研究结果表明:核心温度和皮肤温度均随环境温度的升高而上升,但在较低环境温度下处于非快速眼动时期的核心温度几乎不受环境温度的影响;被褥热阻对核心温度的影响不大,皮肤温度随被褥热阻的增大而上升;核心温度和皮肤温度均随人体与被褥接触面积的增大而上升,但核心温度受接触面积的影响较小。此研究结果将为高性能家用纺织品的开发提供科学的参考。

Abstract:

To optimize the design of bedding systems, the difference of physiological parameters during different sleeping periods was considered. In this research, a four-node thermoregulation model was established and verified, the change of core temperature and skin temperature was predicted, and the effects of ambient temperature, thermal resistance of bedding system and contact area between human body and bedding system on thermal comfort for sleeping human were investigated. The results show that core temperature and skin temperature both increase with the increasing of ambient temperature, whereas core temperature during NREM in low temperature environment is hardly affected by the ambient temperature. The influence of thermal resistance of bedding system on core temperature is not significant, while the skin temperature is kept increasing with thermal resistance of bedding system. The core temperature and skin temperature both increase with the increasing of the contact area between human body and bedding system, but the core temperature is less affected. The results of this study will provide scientific basis for design of high-performance home textile products.

Key words: temperature regulation, thermal comfort, four-node model, bedding system, home textile product
