为了考察冬季供暖期间室外气温变化时不同室内温度对人体生理反应和心理热反应的影响,在散热器供暖的微气候室中,对受试者的皮肤温度、心率和血压等生理参数进行了测试,并对其热感觉和热舒适等主观热反应进行了问卷调查,研究供暖初期、中期和末期人体生理反应和心理热反应的变化规律。结果表明:随着冬季室外气温的下降,人们会更容易从心理上接受偏冷的环境,对室内温度期望不高,在相同的室内环境中感觉越来越热;相同的室外气温下,随着室内温度的降低,人体的皮肤温度会降低,心率下降;当室外气温下降而室内温度相同时,人体手臂皮肤温度显著升高,心率加快。说明随着冬季供暖期室外气温的逐渐降低,人们对偏冷环境的热适应性增强,这为严寒地区人体心理适应和生理习服提供了证据。
In order to investigate the effects of different indoor temperatures on physiological responses and psychic thermal responses to changes in outdoor temperature during winter heating, physiological parameters such as skin temperature, heart rate and blood pressure were tested in a microclimate heated by a radiator , And conducted a questionnaire survey on the subjective thermal responses such as thermal sensation and thermal comfort, and studied the variation rules of human physiological responses and psychological thermal responses in the early, mid-term and end-stages of heating. The results show that with the decrease of outdoor temperature in winter, people will be more likely to psychologically accept colder environments, have less expectation of indoor temperature, and feel more and more hot in the same indoor environment. With the same outdoor temperature, The indoor temperature decreases, the human skin temperature will decrease, heart rate decreased; when the outdoor temperature decreases and the same indoor temperature, the human arm skin temperature increased significantly, heart rate accelerated. It shows that with the gradual decrease of outdoor temperature during the heating season in winter, people’s thermal adaptability to colder environment is enhanced, which provides evidence for psychological adaptation and physiological acclimatization in cold regions.
