Applied Research On Ground Source Heat Pump In Yangling Demonstration Zone

Yangling demonstration zone is a national agricultural high tech IndustriesDemonstration Zone, the only national."1025" period, will focus on "Guanzhong-TianshuiEconomic Zone Development Plan" in the core target of the city planning and construction ofYangling City, to build a "livable Yangling", build "Chinese agricultural Silicon Valley,modern garden city". The construction of Yangling demonstration zone residential area, musttake the construction of green, ecological characteristics district as the goal, to improvepeople’s living conditions and living environment for the purpose of.According to the Yangling demonstration zone expanding supply demand situation,popularization and application of ground source heat pump technology, consistent with theconstruction of a resource-saving and environment-friendly society, but also the need ofYangling demonstration zone of circular economy pilot work. In order to meet the needs ofthe construction of the demonstration zone and the requirements of sustainable development,according to the characteristics of groundwater resources in Yangling demonstration zone andtectonic zoning, centralized heating and cooling utilization demonstration area of shallowgroundwater renewable energy heat pump technology, is a worthy of popularization andapplication of energy-saving demonstration project.In this paper, the application of ground source heat pump technology in Yangling area arestudied, the project research and tracking several application of ground source heat pumptechnology, the geological conditions of Yangling area, the groundwater resources andgeological structure are analyzed, the selection and design of ground source heat pump system,operation analysis of construction process of system analysis and system of buried tube,provides reference for ground source heat pump technology in Yangling area, providesfirst-hand information for optimization design of ground source heat pump, also haveimportant reference value to promote ground source heat pump technology in Yanglingsurrounding areas.The main achievements obtained in our research:1. The Yangling area groundwater resources and geological structure is analyzed,analysis identified in the Yangling area suitable for various conditions and parameters of theground source heat pump technology.2. Put forward to solve the residential heating and cooling problem of ground source heatpump central air conditioning system, based on the cooling load of the seasonal demand,given the configuration and operation mode system. 3.Completed the whole process tracking and analysis of residential area of ground sourceheat pump system buried pipe system construction, the construction of some key parts, suchas buried vertical tube, horizontal tube in detail, provides reference material to complete forthe GSHP system construction.4.Completed the analysis of economic and energy saving of ground source heat pumpsystem, compared with the traditional centralized heating and cooling scheme of householdair-conditioning, compared to the specific data of high investment and low operation,especially in the refrigeration and energy-saving environmental protection, its advantage ismore outstanding.5.Completed the measurement and analysis of summer and winter energy efficiencystatus of ground source heat pump system, combined with the current energy efficiencystandards, energy efficiency index is proposed for the water side of transmission anddistribution system, the user side of transmission and distribution system, heat pump andpump system, analysis of the reasons for the operation of the system does not energy saving.
