Air Conditioning Heat/Cool Source of Xinfei Office Building
Abstract：Compared with the various countries in the world, the current use of our resources and energy level is not high, relatively low per-capita share of resources, which means that our walk saving, sustainable development path is extremely important. In recent years, energy shortage, power shortage situation intensified, the state will promote energy efficiency higher and higher requirements. In the energy sector, improve the heat transfer performance of research and applications have become increasingly urgent. Thus, saving for a building or even a country, it is to be a focus of attention. The graduation project is mainly to Shanghai Xinfei office building be a cold and heat source. According to the mission statement of requirements, the need for air-conditioning system on each floor load calculation, select and cold sources for equipment, room layout, produce drawings, and finally finish the dissertation writing.
KeyWords：Energy saving, heat source, air conditioning load
