Ground-source Heat Pump System Efficiency Analysis

In the current world-wide effort to attain a low carbon economy and the trend of energy saving, ground-source heat pump technology with its significant energy savings in line with environmental requirements and other characteristics of countries in the world attracted the attention. Due to the source warmer than the air source temperature stability, and has energy-saving, the technology has developed rapidly in China and abroad. However, its application requires certain conditions and some application of technology is not yet fully mature, led to the current ground-source heat pump in the application and understanding there is a certain blindness is not conducive to the application of the technology and promotion of. To this end, this paper, theoretical analysis and engineering application of the method of combining the system related to energy-saving effect of quantitative research and analysis.Related to the analysis of ground source heat pump system at home and abroad applied research on the basis of literature, through the eastern Jiangsu ground source heat pump systems, groundwater heat pump systems, surface water heat pump system for research, analysis of the regional application of ground source heat pump system feasibility.With practical examples, application of equivalent full-load run-time method to calculate the area of the system's total energy consumption volume, analysis of ground-source heat pump system, unit energy consumption, energy-saving rate, the amount of energy-efficient alternative to coal.Operating costs through the system unit. Comparison of ground source heat pump air conditioning systems and air-conditioning systems with conventional energy sources the initial investment and annual running costs,then analysis of the system unit energy consumption, energy-saving rate, the amount of coal and other alternative energy-efficient evaluation index.Pairs of ground-source heat pump system brought about by environmental and social benefits evaluation. Come to south-eastern Jiangsu Province, the most suitable form of use of ground source heat pump.
