Analysis & Design Of Ground Heat Exchanger Of Ground Source Heat Pump System

Along with Ground Source Heat Pumps (GSHPs) applying to China, its principiumn of work has been attentionded by people 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.Main content of the paper:1. The factors of affection GSHPs are analysed by ANSYS, and some conclusions are drawed as follow:a) The results of calculation certificate the model of GSHPs when the water flow are unconsiderated.b) The temperature of water in thimble is little affected on the temperature of soil around the thimble.c) Different material of backfill are greatly affected on the soil around the thimble. So the far field soil did .d) The result of of calculation identifies the select of far boundary is reasonable.e) Single row is the best running display of the GSPHs.2. The kinds of ground heat exchanger, the position of pipe, the diameter , length and connection of the pipe, the system of distribution of indoor air are studied. And the factors of affection GSHPs are analysed by ANSYS. The design process of GSHPs is expound.The Ground-Source Heat pump is a fresh domain in china and has a promisingdeveloping. The theoretically model and the way of numerical value calculation will offer accord and referrence to application and study of GSHPs.
