Abstract:

Based on the hydrogeological condition division of Beijing Plain, the numerical model of heat transport was used to evaluate the aquifer energy load capacity per square kilometer on the condition of groundwater heat equilibrium and disequilibrium. The multiple linear regression method was used to analyze the impact of aquifer parameters on energy load capacity, distance between pumping well and injection well. The research shows that energy load capacity is positively related to aquifer thickness, and that distances between pumping-injection wells are positively related to aquifer thickness and permeability coefficient. The results can provide the simple calculating method and reference for groundwater heat pumps plan in similar area to Beijing Plain.

Key words: heat transport, heat pump, energy load capacity, multiple linear regression, Beijing Plain
