Temperature response functions (G-functions) for single pile heat exchangers [PDF]
, 2013 Foundation piles used as heat exchangers as part of a ground energy system have the potential to reduce energy use and carbon dioxide emissions from new buildings. However, current design approaches for pile heat exchangers are based on methods developed

Performance Simulation of Air-ground Hybrid Source Heat Pump Systems in Northern China
Zhileng xuebao, 2021 The air-ground hybrid source heat pump system can realize indirect air source heat pump mode and heat compensation mode through an air-water heat exchanger, which could compensate for the difference between heat extraction and heat injection to the soil.
