Hydro-Geologic Status on the Temperature of Water in Aquifer Surrounded by the Well of Standing Column Well Heat Pumps

摘要

The temperature of water in aquifer surrounded by the well of the standing column well heat pump (SCW), by direct effects of the hydrogeology conditions, will directly impact on the energy efficiency of the heat pump and the life of SCW system. The temperature of water in aquifer surrounded by the well of SCW was simulated in this paper by using finite-difference simulation software, FlowHeat. The results show that both the permeability coefficient and the porosity of the soil around the well have little effect on temperature of the water in aquifer near the production segment of SCW, as well as the smaller the thickness of the aquifer, the larger the temperature change of water in aquifer of the pumping section.
