The simulation analysis of the affection of the water source heat pump of sea water intrusion in coastal region

Pumping a large number of groundwater will bring on sea water intrusion in coastal region, and how to use ground-water source heat pump engine to prevent sea water invasion is a sensitive problem in coastal region achieves more attention. This paper takes the groundwater source heat pump engineering in the progress of designing of a commercial uptown in bayu coastal region adjacent to Liaodong bay in the Bohai Sea as an example. It introduces a simulation which simulates the change tendency of the groundwater flow, mass and temperature in two different schemes of well arrangement, anticipates the influence to sea water intrusion by establishing a groundwater flow, mass and tern the intensive scheme which arrange wells far away from the sea can offer technological thereunder in aspects of preventing sea water intrusion, avoiding heat transfixion among wells and choosing well arrangement project and is worth recommending. At last this paper proves that it is possible to make quantification analysis and arrange pump and reinjection wells advisably by establishing a groundwater flow, mass and temperature coupling numerical model.
