This study aimed to explore the differences in thermal responses of three thermal preference groups of young male university students during summer. A questionnaire was administered to divide participants into three groups: cold thermal preference (Gcp), neutral thermal preference (Gnp), and warm thermal preference (Gwp). Human trials were performed in a climate chamber where the operative temperature was set at 26, 29, and 32 °C to represent three summer indoor environments. The core temperature, skin temperature, conductive heat flux, heart rate, thermal sensation vote (TSV), and thermal comfort vote (TCV) were recorded throughout the tests. The results indicated that the three groups differed (p < 0.05) in core temperature, heart rate, TSV, and TCV in the 29 and 32 °C environments but did not differ in the 26 °C environment. No significant difference was observed in the mean skin temperature between the groups, whereas the local skin temperature differed between the groups at some body segments. The Gwp subjects were more sensitive to indoor temperature variations in skin temperature than the Gcp subjects; however, they were less sensitive to thermal perceptions. Furthermore, differences were observed in the thermal responses of the three thermal preference groups during summer and winter. The findings of this study provide insights into the evaluation of the thermal responses of individuals, indoor environment control, and energy savings in buildings.

这项研究旨在探讨在夏季，三个年轻男大学生的热偏好组在热响应方面的差异。进行了问卷调查，将参与者分为三组：冷热偏好（Gcp），中性热偏好（Gnp）和热热偏好（Gwp）。人体试验是在气候室内进行的，其中工作温度设定为26、29和32°C，以代表三个夏季室内环境。在整个测试过程中记录了核心温度，皮肤温度，传导热通量，心率，热感觉投票（TSV）和热舒适投票（TCV）。结果表明，三组不同（p <0.05）在29和32°C环境中的核心温度，心率，TSV和TCV，但在26°C环境中没有差异。两组之间的平均皮肤温度没有观察到显着差异，而两组之间在某些身体部位的局部皮肤温度却有所不同。与Gcp受试者相比，Gwp受试者对室内温度的皮肤温度变化更敏感。但是，它们对热感不太敏感。此外，在夏季和冬季，观察到三个热偏好组的热响应有所不同。这项研究的发现为评估个人的热响应，室内环境控制和建筑物节能提供了见识。
