Model Considering Thermal Conduction and Groundwater Advection of Soil Viewed as Porous Medium and Numerical Simulation on Soil Temperature Field Around Underground Heat Exchanger
Ground coupled heat pump (GCHP) takes the soil as heat source in heating and heat sink in cooling mode. The soil temperature is higher than the air temperature in winter and lower in summer, so it's advantage for heat transfer to set the heat exchanger in the soil. GCHP can reduce the wastage of coal and save oil and natural gas, which will help the country improve the energy structure and reduce the amount of released gas to protect the environment and achieve the goal of sustainable development. So the GC...
