摘要
被动式超低能耗建筑在国内正处于推广应用的关键时期,其目的是以最小的能耗来满足室内的舒适性要求,然而现有研究多集中在设计、规划阶段的模拟分析。针对此,以寒冷地区某示范项目为案例进行实测研究,基于其室内外环境、分项能耗、机组设备运行等多维监测数据,探索其在不同运行策略下的舒适性和能耗响应特性,提出能够满足其舒适性与节能要求的空调运行策略。结果表明,在超低能耗建筑独有的响应特性下,空调末端混合温度设置运行策略最能满足人体的热舒适性需求,且利于节能;间歇运行策略利于节能,但其机组和水泵的启停波动频繁;考虑寒冷地区的冬夏负荷差异,其空调系统应设置为大小机组,冬季供暖工况时运行小机组来提高系统运行效率。
Currently,passive ultra-low-energy buildings are in a crucial period of promotion and application in China.Its original target is to meet the indoor comfort with minimum energy consumption.However,most of current studies focus more on the simulation analysis at designing and planning stage.Taking a demonstration passive house in the cold area as an example,this study explores the response features of indoor comfort and operation energy consumption under different operation strategies,based on the multi-dimensional datasets of indoor and outdoor environmental factors,subentry energy consumption,equipment operation factors and so on.On this basis,recommended operation strategies,which can meet the requirements of the comfort and energy saving at the same time,can be obtained.Considering its unique responding features,results show that the operation strategy of mixed temperature setting is the optimal one to meet the indoor comfort and lead to the least energy consumption.Although intermittent operating strategies are better for energy saving,the instantaneous power of units and pumps is detrimental to its operating efficiency.In addition,the air-conditioning system is recommended to be set as a large unit and a small unit in cold areas,by considering the load difference between winter and summer.In this way,only the small unit is necessary to be utilized in winter,thus the operating efficiency can also be guaranteed in winter.
