Thermal Response Analysis And Test Of Ground-Source Heat Pump For Ground Burst In Xuzhou Area

The rapid development of today's society,the rapid economic upgrading,but these are based on a large number of energy consumption on the basis of.Through the one-sided pursuit of rapid development and abandon the environment is clearly not desirable.Ground source heat pump as a strong application,wide coverage,energy saving effect of high-tech,has been adopted by some developed countries to slow down the domestic energy crisis,mainly for urban residential buildings and large public buildings,as well as in the suburbs large buildings such as resorts and other areas.In recent years,ground source heat pump in China's continuous development and progress,in line with China's sustainable development path of the established policy in China's energy development plays an important role.In this paper,the thermal response test of the underground heat exchanger in the Xuzhou area is obtained through the whole process.The soil layer structure,the soil heat transfer coefficient,the initial temperature of the soil,the winter and summer Season conditions and the resistance within the tube,these parameters for the ground source heat pump design has a very important reference.Which the specific test of each test and test the principle of a detailed analysis of that.In this paper,the principle,characteristics and classification of the ground source heat pump are introduced in detail.Then,the influencing factors of the heat transfer performance of the ground source heat pump are introduced.According to these influencing factors,the underground heat exchanger test,Including the underground structure test and the ground heat exchanger thermal response test.In this paper,the test of the test were carried out in detail,focusing on the analysis of the principle of the test,by ignoring the axial thermal conductivity and the impact of the various factors between the impact of the theoretical simulation,the use of line heat source simulation and curve The fitting of the numerical calculation,so as to clearly test the required test data and the corresponding program.After confirming the test plan and the test instrument,the test procedure is introduced in detail,and the explanation of the test process should be clarified.At the end of this paper,the data of the test are analyzed and summarized scientifically,and the thermal properties of the soil,the composition of the soil and the soil and the resistance in the pipe are described comprehensively.Through the detailed analysis of the underground structure test and the thermal response test of the underground heat exchanger,the future ground source heat pump design in Xuzhou area has more reference data,and also has some reference for other areas of thermal response test effect.
