Efficiency Analysis Of Ground Source Heat Pump In Energy-Saving Building Based on Multi Target Multi Constraint

摘要

China is a country with a large amount of buildings with astonishing annual building energy consumption, so it becomes necessary to popularize building energy-saving technology. Though ground source heat pump (GSHP) technology is able to considerably reduce energy consumption of buildings' heating, the high initial cost of it becomes a barrier during the process of its popularization. Based on economic dynamic annual cost method, this paper compares the economical efficiency of GSHP system and central heating system. It is concluded that GSHP technology has a higher economical efficiency in the long term which can promote the popularization of building energy-saving technology.
