Application and development of energy storage technology in air source heat pump system

The energy storage technology performs as one method of storing energy, and it can be combined with air source or other types of low temperature heat pump. Therefore, the stability of heat pump system is enhanced in low temperature environment, the imbalance between thermal demand and supply is solved, and the peak load shifting of power can be achieved. This paper mainly summarizes both application and development while energy storage technology is employed in air source heat pump, and introduces the combination of sensible heat storage and double stage coupling heat pump system, the defrosting effect of energy storage technology in cascade heat pump system, the application of heat storage technology in solar heat collection systems, and the new energy storage interconnected heat pump system. By means of analyses, it has better energy-saving effect when the energy storage interconnected heat pump is adopted in low temperature environment, and the obvious research gap exists. In addition, the further research for the structure of energy storage tank, the energy storage materials and the operation strategy is significant.
