装配式建筑作为一种便捷、新兴的建筑形式,值得大力推广.综合评价分析装配式建筑室内热环境、空气质量、能耗等.需要考虑装配式建筑室内温度分布、气流组织和能源系统.根据DeST软件的模拟结果,提出了不同围护结构符合不同气候区室内热环境的平均温度标准(18℃).以夏热冬冷地区为例,利用ANSYS Fluent软件探究室内温度、风速的分布以及室内污染颗粒物的排放特性.并对装配式辅助建筑的供能系统及系统运行性能和成本构成进行研究.结果表明,在冬季(4.1℃)和夏季(31.1℃)典型日的室内平均温度条件下,出于考虑人体热舒适需求,应启动空气源热泵.此外,污染颗粒释放后室内空气质量能够满足洁净度标准.
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.
