Study On Human Physiological Thermal Response And Its Change Regularity Of Different Physique

People spend most of their time in the indoor environment,relying on the heating and air-conditioning environment for the transition,which accelerates the heating and air-conditioning energy demand and causes a lot of building energy consumption.To this end,this topic has carried out the study of human thermal response,focusing on the sensitivity and changing characteristics of human physiological parameters.Through this research,it provides a theoretical basis for the design of green buildings and achieves the goal of building energy conservation.This article selects the combination of physiological parameters and psychological reactions,and through experimental tests,studying the change of human thermal response base on different physique under different seasons and environmental conditions.The experimental test results are as follows:In the winter steady-state environment,physiological parameters analysis of cold-resistant and non-cold-resistant human shows that: with the decrease of the ambient temperature,the skin heat flow of two kinds of physical human increases and the skin temperature decreases.The skin temperature of the non-cold-resistant human is higher than that of the cold-resistant human,the skin heat flow is lower than that of the cold-resistant human,and the difference is significant(P<0.5).The skin heat flow and skin temperature can be used as sensitive physiological parameters to test the cold-resistant and the non-cold-resistant human.With the decrease of the ambient temperature,the heart rate of the two kinds of physical human decreases,and the heart rate of the non-cold-resistant human is higher than that of the cold-resistant human,but the individual differences of heart rate of the human is relatively large.Whether heart rate can be used as a sensitive physiological parameter remains to be further verified.With the decrease of the ambient temperature,the heart rate variability of the two kinds of physical human is not obvious,and individual differences are large.The heart rate variability is not recommended as a sensitive physiological parameter to test the cold-resistant and the non-cold-resistant human.In the winter non-steady-state environment,physiological parameters analysis of cold-resistant and non-cold-resistant human shows that: when the temperature is decreased at a rate of 0.2?/min,the skin heat flow of two kinds of physical human increases,the skin heat flow of the cold-resistant human is higher than that of the non-cold-resistant human.The skin heat flow can be used as a sensitive physiological parameter to test the cold-resistant and the non-cold-resistant human.With the rapid decrease of temperature,skin temperature,heart rate and heart rate variability of two kinds of physical human have small changes,and individual differences are large.So,they are not recommended as sensitive physiological parameters to test the cold-resistant and the non-cold-resistant human.In the summer steady-state environment,physiological parameters analysis of heat-resistant and non-heat-resistant human shows that: with the increase of ambient temperature,the skin heat flow of two kinds of physical human decreases(P<0.5),the skin temperature increases(P<0.05),The skin heat flow of the heat-resistant human is higher than that of the non-heat-resistant human,the skin temperature is lower than that of the non-heat-resistant human,and the difference is significant(P<0.05).The skin heat flow and skin temperature can be used as sensitive physiological parameters to test the heat-resistant and the non-heat-resistant human.With the increase of ambient temperature,heart rate of two kinds of physical human have small changes,the heart rate of the non-heat-resistant human is higher than that of the heat-resistant human,and individual difference is larger.It is not recommended as a sensitive physiological parameter to test the heat-resistant and the non-heat-resistant human.With the increase of ambient temperature,the heart rate variability of the heat-resistant human is bigger than that of the non-heat-resistant human,but individual difference is larger.Heart rate variability is not recommended as a sensitive physiological parameter to test the heat-resistant and non-heat-resistant human.In the summer non-steady-state environment,physiological parameters analysis of heat-resistant and non-heat-resistant human shows that: when the temperature is increased at a rate of 0.33?/min,the skin heat flow of two kinds of physical human increases,and the skin heat flow of heat-resistant human is higher than that of non-heat-resistant human.The skin heat flow can be used as a sensitive physiological parameter to test the heat-resistant and the non heat-resistant human.With the rapid increase of temperature,skin temperature,heart rate and heart rate variability of two kinds of physical human have small changes,and individual differences are large.So,they are not recommended as sensitive physiological parameters to test the heat-resistant and the non-heat-resistant human.There are 60 pictures,21 tables and 72 references in this article.
