Prefabricated building,as a convenient and burgeoning building form,is worth popularizing.The research aims to comprehensively evaluate and analyze the indoor thermal environment,air quality,and energy consumption of prefabricated buildings.Therefore,indoor temperature distribution,airflow distribution and energy system of prefabricated buildings are considered.According to the simulation results of DeST software,different enclosure structures are proposed to meet the average temperature standard(18℃)of indoor thermal environment in different climate zones.Taking the hot-summer and cold-winter region as an example,the distribution of the indoor temperature,air velocity and the emission characteristics of indoor polluted particles are explored via ANSYS Fluent software.And the energy supply system for the prefabricated auxiliary building,as well as system operation performances and cost components are studied.Results show the average indoor temperature on typical days in winter(4.1℃)and summer(31.1℃),air-source heat pump needs to activate for the needs of human thermal comfort.Moreover,the indoor air quality can meet the cleanliness standard after polluted particles release.
