Technic-economic analysis of series connected hybrid ground source heat pump systems

Taking a commercial building in Zhuzhou city, Hunan Province as the research object, simulates its annual load with EnergyPlus. On this basis, calculates the initial investment, operating cost, total cost and the life cycle cost of the system in which the cooling tower and the ground exchanger shares different proportion of the cooling load. The results show that the improper configuration of a hybrid ground source heat pump system will result in diseconomy.
