Technology Of Low Enthalpy Geothermal Engineering And It's Application

Abide by the design concept of"none-liner integration", the thesis expatiates the technology of low enthalpy used at the Institute of Airforce Equipment.Technology of low enthalpy Utilization is a series of technologies which join with each other tightly and form a whole part. It employs a"Air-conditioning System of Stratum Energy Stored (ASSES)"which"store up cool energy in winter while use it in summer"and"store up hot energy in summer while use it in winter"and integrates the underground system & ground system to form a unified energy utilization system.According to the standpoint of the systematic theory, the thesis regards the whole procedure of low enthalpy geothermal as a consecutive organic whole. Firstly, it uses numerical simulation technology to analyze the underground hydraulic condition and heat condition which influence energy stored effect and get the proper layout of pumping well and injecting well. Basing on the result of numerical simulation and combining with analytic solution and practical project experience, we design the underground system.It is heat pump system, the energy extracting and transforming device, that couples underground system and ground system. Pumping& injecting well system and heat pump system constitute the output end, ie."heat supplying end", which forms the whole energy self-circling system along with"consumer's end". Reflected in design, the relationship of heat supplying end and consumer's end contributes to the key technology of low enthalpy, ie. double-ended design technology, which includes"optimizing design at the heat supplying end"and"rebuilding design at the consumer's end". According to principle of"differentiating treatment, efficient management", we put forward and implement"consumer sectioning design technology"to distribute energy reasonably. According to the sequence and relationship of each part when conduct the project, we bring forward"triple-system coupling system"which include pumping& injecting well system, heat pump system and heating system to ensure the successful accomplishment of the project. Cater to the demand of intelligentized control, we put forward"whole process multi-parameter...
