A Field Study Of Thermal Comfort In Large Commercial Complex In Xi’an,China

With the continuous development of urbanization,commercial buildings are developing rapidly in large and medium-sized cities,becoming the main choice of residents for leisure,shopping and entertainment.With the continuous improvement of people’s living standards,people’s requirements for indoor experience and comfort of commercial buildings are also improving.The operation of large commercial complexes requires huge energy consumption.A large number of cases built in recent years in China have reflected its high energy consumption and the problems such as high indoor temperature and low relative humidity in the process of improving indoor environment quality.Under the circumstance that the world is facing the energy crisis,it is of profound significance to strengthen the research on the indoor human comfort of large commercial buildings to improve the indoor comfort of commercial buildings,reduce the energy consumption of public buildings,and guide the design and operation of large commercial buildings.With the help of some shopping malls in xi ’an,a typical city in the cold region,as the research objects,this paper adopts the research method of subjective evaluation of the thermal environment of buildings,and combines strict and rigorous objective data measurement to make an in-depth analysis and research on the thermal comfort of largescale commercial integrated internal space.This article selects the case for xi ’an nine typical large commercial building,by measuring the four seasons in a year flow peak of indoor environment parameters,and the applicable people in stores random questionnaire to fill out and the result of the test statistics,commercial building indoor thermal environment for the scientific analysis,identify the reasons for the shortfalls and thermal comfort.In addition,it provides reasonable thermal comfort index for large commercial buildings in cold regions,and puts forward improvement strategies for improving indoor thermal comfort of large commercial buildings,providing scientific basis for the design and operation of commercial buildings.The purpose of this paper is to provides technical support for the improvement of the thermal environment of large commercial buildings in cold regions of China in various seasons,and helps to improve the environmental quality of urban life.
