Thermal Analysis Of Ground Heat Exchangers For Ground-Coupled Heat Pump Systems

Along with Ground-Source Heat Pumps (GSHPs) applying to China, its principiumn of work has been attracted by more and more. Many companies have obtained substantial production, including many universities ,institutions for scientific research and companies associated, they work hard on studying GSHPs. On the base of departed production ,the paper set up the heat transfer model and study on it. And then, analyse the factor of affection the heat transfer using numerical value model. According to the result ,the paper study and confirm some parameter for design of GSHPs. It may be simply expound of the design process of GSHPs , which can be a reference of the theory research and the practical design.This article in the topic-based group, was 600 square meter alone villas has developed a set of complete place source heat pump heating system.This paper introduced some hypothesis to make models and several typical models in detail. The models include line-type and cylindrical type and U-type. We compared these models and present some charts of the models.This paper introduced the theory of finite element and the information of the software. It illustrated the function of the finite element analysis software. The analysis process includes modeling, making gridding, restricting boundary condition, initializing, loading, computing and result treatment etc.The Ground-Source Heat pump is a fresh domain in China and has a promising developing. The theoretically model and the way of numerical value calculation will offer accord and reference to application and study of GSHPs.
