The Application Of The Vertical Borehole Ground-source Heat Pump In The Business Buildings

Confronted with the lack of resources and deterioration of environment,peoplepay more and more attention to a new method of resources developing,which is thetechnology of Ground Source Heat Pump(GSHP).With its upstanding energy savingperformance and excellent environmental protection function,the GSHP technologyhas brought more and more attention to the domestic and international experts inrecent ten years and acquired the substantial development in our country,particularlyin the aspects of actual applying.This paper give a minute description of the GSHP's principle and the designrequirements.With being started from the principle,characteristics and engineeringapplication of GSHP,the heat transfer performance of the underground verticalborehole heat exchanger was analyzed theoretically.And the general formula used inengineering application was introduced.Combining with the model project of the underground vertical boreholeground-source heat pump by Tianjin Zhong Leng heating ventilation and cleaningproject technique Co.Ltd, the complex construction program have been analyzed indetail,and introduced the new method in plugging PVC tube.Some principles are submitted to analysis performance of energy saving andeconomization of the underground vertical borehole ground-source heat pump.Basedon the project of the underground vertical borehole ground-source heat pump used inthe business buildings,this heating(cooling) system's economization and energysaving are be analyzed particularly.At the end of this thesis,the environmental benefits of the GSHP are be briefanalyzed.Through compared with the other heating(cooling) forms,the advantages ofthe underground vertical borehole ground-source heat pump is obviously.And theapplication of GSHP is extend in our country.
