Study On The Application Of Water Source Heat Pump

Water Source Heat Pump System (WSHPS) is widely used in our country recently, but it has been used blindly in some areas without thinking its actual status. In order to guide WSHPS rightly used in more situations, this paper introduces its principle briefly and analyses its applying conditions and system styles according to the characters of WSHPS.The problem of re-pouring ground water is key technology and difficult point in applying ground water source heat pump. The problem is analysed specifically and detailed in this paper. And putting forward a lot of method to resolve the problem. Besides , the paper have introduced other factors affecting re-pouring simplely. Including the collocation of drawing-pouring well, and structural design of drawing-pouring well. Two engineering examples are given in the articles.The quantity drawing-water and pouring-water of drawing-pouring well is an important influencing factor in the utilization of SWHP, and is one of scale standards of the worth of well and the fixed number of year of SWHP. In the actual utilization of SWHP, the quantity of re-pouring is one of the leading problems. Considering its location of re-pouring well and quantity of re-pouring, and arrangement of the lithology of the hydrous stratum, and the embedding depth, the account of the quantity of re-pouring of one well lies on the size and arrangement of the granule in the hydrous stratum, and the thickness and penetrability of the hydrous stratum, and drilling flush fluid and the course of flushing and re-pouring.Through counting the investment and testing the power consumption of the engineering in shen yang city, the thesis draws the investment cost and the annual running cost of the Ground-Water Source Heat Pump system, and then adopts the annual cost method and compares with other schemes and defines the best scheme under different situation at last.The last part of thesis analyses that the application of the Ground-Water Source Heat Pump system puts impact on the environment. Through testing and determining the consumption of the Ground-Water Source Heat Pump system, the thesis compares with other schemes' consumption and defines its energy-efficiency and environmental- efficiency at last.
