Performance of energy storage air source absorption heat pump
A heat storage system based on air source absorption heat pump is proposed.The mathematical model of the system is constructed,its operation characteris-tics 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 × 105 kJ/m3.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 ur-ban central heating method,the payback period of the energy storage air source absorption heat pump system is 3.89 years.
