Ground Water Heat Pump is a system that use heat pump technology to achiv e the goals that energy can be transferred from low to high and supply heating or cooling for users, while just need groundwater as a low grade heat and a small n umber of high grade energy as input.Ground Water Heat Pump technology has been the public's favor now for its energy-saving, environmental protection and low operation cost advantage. In the us e of Ground Water Heat Pump system, in addition to the amount of groundwater e xtracted enough, it should also put the same amount of groundwater recharge to th e aquifer original to make recycling of water resources, and therefore to explore th e characteristics of the source of recharge wells group particularly important.This article selects a Ground Water Heat Pump and Ice Storage system of a b uilding in Wuhan as a research reference system. According to the relevant design drawings, determined the calculation parameters. Use Flowmaster fluid simulation s oftware to establish a baseline model, and analyze the hydraulic characteristics of f low distribution characteristics under different conditions through simulation, thus we can know whether the flow of source side water system to meet the design re quirements, and find whether the current system belongs to gravity or pressure rec harge. Finally, find the main reason that water overflow out the recharge wells, an d propose optimal operation scheme.Ground Water Heat Pump system simulation mainly refers to the simulation of the recharge process by using fluid systems simulation software. By simulating th e recharge process of Ground Water Heat Pump system in different conditions, dra w the flow and other parameters can be achieved after running pressure in actual design parameters, and compare with the test results that the recharge flow amount and pressure conditions in different recharge. Before the water systems simulation we should take an experimental verification for the software, to ensure the feasibili ty of the simulation. Simulation tool is Flowmaster fluid simulation software, the b ench for verification experiments is a scaled-down water and recharge system benc h.In this paper, we have analyzed the characteristics for 16 exhaust conditions and 34 water recharge conditions, and have analyzed the operating running for 2 operating conditions in winter and summer, and got the best method of adjusting the val ve opening.
