Abstract


Soil heat transfer model is the emphasis and difficulty of the study of ground source heat pump technology . Considering groundwater seepage soil heat transfer model is more complex . China 's southern region is rich groundwater to analyze soil heat transfer can not ignore the impact of groundwater in the area . With the help of MATLAB consider the finite length of the groundwater convection heat source model . C # language preparation of soil heat exchanger design , economic analysis of the thermodynamic calculation of the cooling tower and ground source heat pump system visualization applications . The main content of this study are: ( 1) soil heat exchanger drilling to consider groundwater convection heat source model of limited long-term , the model can be used for analysis of soil heat exchanger exothermic and endothermic work , can also be used to simulate U -tube , double U-tube and casing a variety of forms of soil heat exchanger buried temperature field, the impact of changes in soil heat exchanger temperature field can also be used to study the performance parameters of geotechnical or backfill material . (2) soil heat exchanger design calculation modules written in C # , the module can be used for solving the drilling heat flux intensity . Practical engineering analysis of convective heat transfer coefficient , drilling spacing and backfill materials for soil heat transfer . ( 3) preparation of the cooling tower thermal calculation visualization application modules . The module can be used for both endothermic and exothermic work of the cooling tower . Cooling tower heat transfer model and soil heat transfer model combined to enrich the soil heat exchanger - hybrid cooling tower system the matching optimization design theory knowledge . ( 4) the preparation of a ground source heat pump system economic analysis module . Economic parameters: software to calculate the net present value , net present value , rate and payback period can choose the basis of the construction program as an engineering technician , also can be used as the basis of the project bidding options .
