Hybrid System On Solar Energy And Underground Thermal Energy Storage For Engineering Applications

The shortage of energy sources and environmental pollution are becoming the two focuses of the society. Exploring and using renewable and new energy sources to replace the traditional petrochemical energy sources are the main approaches for solving the faced problems. As a typical representation of using renewable energy sources, heat pump economizes energy sources and is good to environment. So, it has already aroused the interests of the people and got quick development.During the design process of the heat pump, computer numerical simulation analysis and capability forecast are the main technical means for the developing of modern technology, they can make up the limitations of the experiment and develop broader analysis of the complex processes. They are identified by the scientific community as numerical experimental methods. So, this thesis will use HVACSIM+ numerical simulation software for the exploring design and capability analysis of the heat pump with hybrid energy sources.This thesis is to append assistant energy sources such as collected solar energy in traditional Ground Source Heat Pump System, and form Solar Energy-Ground Source Heat Pump System, at the same time, during the applications, this study raises the Pavement Heat Collected & Snow Melting & Deicing Ground Source Heat Pump Hybrid System, and hopes that it can initiate the new snow melting and deicing technologies of our nation, and make the design analysis of processes of building heating and snow melting and deicing, and also make an analysis for the precipitation capability forecast of circulating patterns. By analyzing the heat transfer process of these two application processes, it establishes the mathematical models for the composing units, and uses the HVACSIM+ software analysis tool for many factors'systemic analysis and research, and, it emphasizes the influencing rules and Coefficient Of Performance of nature environmental factors.On the base of the built mathematical models, this research programs the unit models of SE-GSHPS and PHC&SM&D-GSHPHS for the HVACSIM+ software, and then using systemic conformity simulation analysis, it analyzes and studies on the capability of different circulating configuration and snow melting and deicing and rules of varies. It makes a short and a long term analysis on the snow melting and deicing and underground thermal energy storage and circulating performance characteristics towards the pavement heat collected and snow melting and deicing, and it also analyzes the influencing characteristics of the heat pump for the different snow fall, different environment temperatures, different initial underground temperatures, whether has Underground Thermal Energy Storage and different borehole numbers. The research makes a basement for the study of Ground Source Heat Pump, Underground Thermal Energy Storage, solar energy using and practical engineering applications, and promotes the Ground Source Heat Pump to a broader developing field.
