文摘

In order to grasp the energy-saving potential of air conditioning system in severe cold region, choosing a nearly zero energy consumption building in Shenyang of China as research object. The concepts of green building and passive building, and many building energy efficiency technology such as phase change energy storage, exhaust air heat recovery, tunnel wind, low-e glass, outside wall insulation, are used in the process. Using the DeST software to establish a physical model and though simulating the heating and cooling load of building air conditioning system to research the Air conditioning system load variation and influencing factors and compare with the same type of conventional building energy consumption. Nearly zero energy consumption building's winter heating load has reduced 73.72% compared with the common building, and the comprehensive energy saving rate is up to 55.22%. The air conditioning system has great energy saving potential.
