Design and application of key technology to water-source heat pump system for a projeet in Wuhan

Applies a water-source heat pump central air conditioning system to a project in Wuhan, due to the rich geothermal resource and the hot summer and cold winter climatic condition in Wuhan. Presents the profile and pumping and recharging test of the project. Establishes and analyses a model of the well group system by Modflow software. In view of the pumping and recharging test, summarizes the law of ground-water seepage field. According to the problems in the simulation results and experiments, adopts a two-pipe pumping and recharging well and arranges the well group based on three dimensional finite difference simulation test method, and forms a set of scientific and reasonable method for ground-water pumping and recharging. The method has been successfully implemented in a project in Wuhan, with stable operating in recent years and low operating cost.
