Ground Source Heat Pump Technology And Its Energy Saving Potential

In today's world,Energy is a development problem.Although China's total energy amount is larger,our energy use situation is not optimistic due to large population,low per capita hold of resources and low energy utilization efficiency which under coal –based energy reserves.With the rapid development of our country's economic and the continuous improvement of people's living standards,the sustainable development has became the only way for a country's development all over the world in contemporary society.Thus,the renewable energy technology has been stressed by increasingly more and more countries.This article mainly introduced application of Ground Source Heat Pump Technology in Energy Saving of Building Air Conditioning.Firstly,this paper introduced historical progress of Ground Source Heat Pump Technology development,discoursed overseas and domestic research status of Ground Source Heat Pump Technology,presented influencing factor of ground source heat pump operational efficiency and restricting factor of Ground Source Heat Pump Technology development.By analyzing climate feature for the hot summer and cold winter region,we expounded the need for heating supply of this region,imported the advantage of ground-source heat pump system applied in the hot summer and cold winter region.Secondly,this paper listed ground-source heat pump system classification: soil source heat pump system,groundwater source heat pump system and surface water source heat pump system.We discussed ground source heat pump air conditioning system's working principle and merit and demerit for the application of GSHP technology.Selection criteria of ground-source heat pump system have also been introduced.Because the economic benefit and environmental protection benefit of GSHP system is not clear in actual operation evaluation system,in actual running progress,the system often can't reach setting running effect.This paper introduced valuation theories and methods of GSHP system.Take Wuhu actual project as an example,we used the thermal response test to measure thermal properties of soil parameters in this area,introduced design solution of GSHP,analyzed the prospects and the risk of GSHP technical scheme,and presented construction scheme and matters need attention of ground heat exchanger.Hefeipractice project,for instance,on the basis of long-term running measured data,we analyzed expense and energy-saving potential for GSHP system.The Ground Source Heat Pump Technology,as an energy-efficient renewable energy utilization technique,the research of this technology can promote a sustainable and healthy development and has more significance in practice.This topic did systematical demonstration for the GSHP technology,thus it will be reference for the application of GSHP technology.
