Energy tower heat pump systems and their heating performance analyses

Presents the operation principle of the energy tower heat pump system and the properties of refrigerating medium solution, and establishes a mathematical model of hygroscopic capacity. Tests and analyses the heat capacity and the coefficient of performance (COP) of energy tower heat pump at different wet bulb temperatures. With an application example in Nanjing, calculates the heating seasonal performance factor (HSPF). The result shows that the energy tower heat pump system is feasible in the high humidity areas such as the Yangtze valley.
