The Predicted Mean Vote and Predicted Percentage of Dissatisfied (PMV/PPD) method is used worldwide to assess thermal comfort. The PMV/PPD method traditionally depends on four environmental parameters; air temperature, relative humidity, mean radiant temperature and air velocity, and two personal parameters; metabolic rate and clothing insulation. However, accurate modelling of thermal comfort requires consideration of psychological impacts, as well as associated physical responses to the environment. This paper investigates the effect of one of the psychological parameters; stress level on the thermal sensation of students for male and female which can be a sufficient limitation of the accuracy of thermal comfort/sensation models. Actual Thermal Sensation (ATS) and Profile of Mood States (POMS) are used to examine the effect of stress level on the thermal sensation. Pre-test-Post-test Control (PPC) experimental design is conducted on the students in a university, Ankara, Turkey, which has a Csb type climate zone according to Köppen-Geiger climate classification. First, students are split into two random groups; control and experimental groups. The students in experimental group are requested to attend exam while the students in control group read their favourite books. Then, students are subjected to pre-and post-exam surveys in order to understand the relationship between stress level and ATS. As a supportive analysis, Heart Rate (HR) and Skin Temperature (ST) are also included in the study as sympathetic responses of occupants to the thermal discomfort due to stress. Smart wristbands and infrared thermometers are used to measure Heart Rate and Skin Temperature of the students. Results showed that there is a difference between control group and experimental group before the exam (pre-test) except the ST of females. After the exam (post-test), there are no significant differences between two groups.

考前、考后压力水平对学生热感觉的影响


预测平均投票和预测不满意百分比 (PMV/PPD) 方法在全球范围内用于评估热舒适度。 PMV/PPD 方法传统上取决于四个环境参数；空气温度、相对湿度、平均辐射温度和空气速度以及两个个人参数；新陈代谢率和衣服隔热。然而，热舒适度的准确建模需要考虑心理影响以及对环境的相关身体反应。本文研究了其中一项心理参数的影响；男性和女性学生热感觉的压力水平可以充分限制热舒适/感觉模型的准确性。实际热感觉 (ATS) 和情绪状态轮廓 (POMS) 用于检查压力水平对热感觉的影响。测试前-测试后控制（PPC）实验设计对土耳其安卡拉一所大学的学生进行，该大学具有根据柯本-盖革气候分类的 Csb 型气候区。首先，学生被随机分成两组；对照组和实验组。要求实验组的学生参加考试，而对照组的学生则阅读自己喜欢的书籍。然后，学生接受考前和考后调查，以了解压力水平与 ATS 之间的关系。作为支持性分析，心率 (HR) 和皮肤温度 (ST) 也包含在研究中，作为乘员对压力引起的热不适的交感反应。智能手环和红外测温仪用于测量学生的心率和体表温度。 结果显示，对照组与实验组在考试前（预测）除女性ST外均存在差异。考试后（post-test），两组之间没有显着差异。
