摘　　要：提出一种基于空气源吸收式热泵的蓄热系统,构建系统数学模型,通过Matlab软件模拟运行,研究其运行特性并进行性能分析和经济性分析。蓄能型空气源吸收式热泵蓄能供热工况和释能供热工况的能量效率分别为0.58和0.99,系统总的能量效率为1.57,蓄能密度为6.17×10^(5)kJ/m^(3)。蓄能型空气源吸收式热泵在低谷时段进行蓄能,非低谷时段释能,有效降低供暖季运行费用,与传统的城市集中供热方式相比,蓄能型空气源吸收式热泵的投资回收期为3.89年。A heat storage system based on air source absorption heat pump is proposed.The mathematical model of the system is constructed,its operation characteristics are explored through the simulation by Matlab software,and its performance analysis and economic analysis are analyzed.The energy efficiencies of the energy storage air source absorption heat pump system under energy storage and releasing energy heating conditions are 0.58 and 0.99 respectively.The total energy efficiency of the system is 1.57,and the energy storage density is 6.17×10^(5)kJ/m^(3).The energy storage air source absorption heat pump stores energy at low valley period and releases energy at other period,thus it can decrease the operation cost in heating season effectively.Compared with the traditional urban central heating method,the payback period of the energy storage air source absorption heat pump system is 3.89 years.
