The hybrid heat pump system of air source auxiliary ground source is one important approach to solve the imbalance problem of soil heat absorbing and releasing for ground source heat pump. Meanwhile, this is also one effective way for achieving high-efficient utilization of renewable energy, especially in poor areas of renewable energy. As to the problem of renewable energy applied in Chengdu city, the energy consumption of hybrid heat pump system of air source auxiliary ground source was simulated by EnergyPlus in the present study. Moreover, variation characteristics of hourly energy efficiency, power consumption and heat absorbing and releasing of underground pipe were analyzed. The differences of this system operation under different load matching conditions were obtained. The research finding provides the meaningful guidance and bases for the design and engineering application of hybrid heat pump system of air source auxiliary ground source in poor areas of renewable energy.
