Simulation Analysis of Underground Temperature Field Changes of Groundwater Source Heat Pump under Different Layout of Wells
In view of the impact of layout of pumping wells and injecting wells of groundwater source heat pump on the underground temperature field,the coupling model between groundwater flow and temperature is established.From two aspects of the pumping and injecting wells' space and number,groundwater temperature variation trend and the basic characteristics of thermal penetrating are simulated and analyzed under different layout well modes.The results show that the similar wells distance have little impact on the thermal penetrating; the distance of pumping wells and injecting wells affect pumping temperature and thermal penetrating time significantly; the more number of pumping and injecting have,the more thermal penetrating time delay; for long term operation of the system,the number of pumping and injecting wells does not affect pumping temperature significantly.
