空气源热泵直接地板辐射供暖系统优化运行方式

Research of Optimizing Running Modes for Direct Radiant Floor Heating System with Air Source Heat Pump

从运行方式的角度对空气源热泵直接地板辐射供暖系统进行优化,以山西某栋两层居住建筑为例,将实测数据与DeST-h软件模拟数据进行结合,比较全天连续运行、白天运行夜间停机、电价移峰填谷运行三种不同运行方式的经济性和舒适性.结果表明:三种运行方式均可基本满足舒适性的要求,但就经济性而言,白天运行夜间停机的运行方式既充分利用围护结构的蓄热能力,又缩短了系统运行时间,因此为最佳运行方式.

From the aspect of running modes,direct radiant floor heating system with air source heat pump was optimized.Installing this system in a two floor residential building in Shanxi Province,three different running modes,including all-day continuous running,intermittent running（daytime on and nighttime off）,and electrovalent peak load shifting running,were compared the economy and comfort by combining the measured and simulative data from the DeST-h software.The results showed that the three running modes could all meet the comfort requirement basically,but the intermittent running could also make full use of the thermal storage capacity of the building envelope and shorten the running time economically,which indicates that the intermittent running is the best way to run.
