Study On The Influence Of Architectural Space Scale On Human Thermal Comfort

Space has been existed for thousands of years with the emergence and development of the building,meanwhile,it is continued to develop with the development of the construction and update of technology.The research between building space and human environment is often focused on the forms of space,beauty,environmental psychology,architectural phenomenology and so on.With the continuous development of society and the popularization of air conditioning,the requirements of indoor space thermal environment is becoming higher.It is important to study the architectural space from the angle of the spatial scale to the thermal comfort of the human body,which is of great significance to expand the research scope of architectural space and enrich the architectural design.The experiment is divided into summer and winter from July to September in 2016 and December 2016 to January 2017,which is in the space environment experimental cabin.32 students in Tianjin were selected as subjects(male and female ratio: 1: 1)in the space environment laboratory,and the thermal comfort questionnaire and spatial sensory questionnaire survey were conducted.There were three types of plane sizes: 6M(length)3 6M(width),12M(length)3 12M(width),24M(length)3 24M(width).The height was: 3M,5M,7M,9M.Summer temperature gradient: 25 ?,27 ?,29 ?,winter temperature gradient: 18 ?,20 ?,22 ?.Firstly,the effects of height changes on the spatial sensation and emotional and skin temperature of the subjects were analyzed.Then the method of linear regression was used to calculate the thermal and thermal acceptor temperature and the ratio of thermal comfort and heat expectation in summer and winter.The conclusions and results are as follows:One,Evaluation of spatial spatial variation and spatial influence of spatial height in different plane scales(1)The height change of 3M-9M has a significant effect on the height perception of the subject,which has an effect on the sensation of the subject area.(2)The change of space height has no obvious effect on the overall evaluation of space.The height change of 3M-5M will improve the spatial satisfaction,under the individual plane conditions.(3)Changes in space at all plane scales have no significant effect on subject mood and skin temperature.Two,Influence of space height variation on human thermal comfort under different planar.(1),The thermal neutral temperature and the heat accepting temperature rise from the 3M to 9M during summer and winter,and the difference of it is less than 1 ?.(2),the height of the heat for the comfort,heat expectations do not have a significant impact during summer and winter in all the plane scale.
