Skin temperature is an important physiological parameter that reflects human thermal sensation. However, it is uncertain whether it can evaluate overall thermal sensation in non-uniform thermal environments. This study aims to explore the feasibility of using skin temperature to predict overall thermal sensation in non-uniform environments. The overall thermal sensation votes and skin temperatures were obtained in a non-uniform thermal environment with local cooling on the chest in a climate chamber. The predictive power of the representative skin temperature (RST) estimated from five different methods was examined by analysing its sensitivity and the correlation between the overall thermal sensation and the RST. The RSTs estimated from the 7-point method with the measurement site of trunk assigned on the chest and the 1-point method with a measurement site at the centre of the chest had high sensitivity and coefficients of determination. They could reflect overall thermal sensation in the non-uniform environments with local cooling on the chest. The results imply that skin temperature could be used to evaluate overall thermal sensation in non-uniform environments. The overall thermal sensation in non-uniform environments can be evaluated by the RST if, when determining the RST, the measuring site exposed to local cooling is involved and given a high weight.
皮肤温度是反映人体热感觉的重要生理参数。然而，在非均匀热环境中，皮肤温度是否能够评估整体热感觉尚不确定。本研究旨在探讨使用皮肤温度预测非均匀环境中整体热感觉的可行性。在气候室内，通过对胸部局部冷却来实现非均匀热环境，获取整体热感觉投票和皮肤温度。通过分析代表性皮肤温度（RST）与整体热感觉之间的灵敏度和相关性，检验了五种不同方法估算的 RST 的预测能力。当测量部位选择在胸部且使用 7 点法或测量部位选择在胸部中心且使用 1 点法时，估算的 RST 具有较高的灵敏度和决定系数。它们可以反映出胸部局部冷却的非均匀环境中的整体热感觉。结果表明，皮肤温度可用于评估非均匀环境中的整体热感觉。如果在确定 RST 时涉及到暴露于局部冷却的测量部位，并给予其较高权重，则可以通过 RST 来评估非均匀环境中的整体热感觉。
