Analysis and comparison of different control strategies for hybrid ground-source heat pump systems

Provides control strategies being applicable for two kinds of common hybrid ground-source heat pump systems—the cooling tower-ground source heat pump system and the boiler-ground source heat pump system. Selecting Wuhan and Harbin as representative cities and taking a small-sized office building as study object, simulates the operation conditions of the two systems under different control strategies, and analyses and compares the heat balance and energy consumption.
