Study On The Effects Of Thermaland Color On Human Comfort

In recent years,with the development of society and science and technology,many scholars at home and abroad have done a lot of research on the single factors such as thermal comfort and light comfort.But in real life,we are stimulated by multiple factors at the same time.Therefore,it is very necessary to explore the comfort degree of human body under the influence of complex factors.This paper studies from the perspectives of medicine,physiology,psychology and Physics,two methods of subjective questionnaire survey and objective measurement are used.The experiment was carried out in the environmental simulation room of our university,and the comfort degree of human body under the influence of temperature and color complex factors was studied.The subjective questionnaire mainly investigated people's thermal sensation,thermal comfort,and environmental comfort,objective measurement mainly measured two physiological parameters of heart rate and blood pressure of human body.The main contents of this paper are as follows:(1)In this paper,the change rules of various evaluation indexes under different temperature levels and environmental color types are explored,these indicators include thermal comfort,thermal sensation,and environmental comfort.The experimental results show that temperature and environmental color will affect these indicators.Warm colors can improve people's thermal sensation,reduce the discomfort value in the partial cold environment,and improve the discomfort value in the thermal environment;Cool colors can reduce people's thermal sensation,improve the discomfort value in the partial cold environment,and reduce the discomfort value in the thermal environment.(2)Temperature and color will affect the comfort of the environment.The more the temperature deviates from the heat neutrality,the worse the comfort of the environment,the closer the temperature is to the neutral temperature,the better the comfort of the environment.The influence of color on environment comfort isdifferent because of the different attributes of color itself.(3)The change rule of two main physiological parameters of heart rate and blood pressure under different temperature and environmental color was studied.It was found that the two factors could produce significant influence.With the increase of temperature in a certain range,lower blood pressure,heart rate;the decrease of temperature,blood pressure,heart rate slowed down.In the red,yellow environment,within a certain range of human heart rate increased,blood pressure increased;in green,blue environment,the human heart rate slowed down,blood pressure decreased We can generalize the conclusion to other fields.(4)The index of prediction dissatisfaction rate under the influence of temperature and color composite factors is defined,and the comfort range of human body under the combined action of temperature and environment color is obtained.In the cold tone color environment,comfortable range slightly upward,in the warm tone color environment,comfort zone is slightly down.
