摘要:与世界上各个国家相比,我国目前的资源和能源利用水平不高,人均资源占有率相对较少,这意着在我国走节能、可持续的发展道路极其重要。近年来能源短缺、电力供应紧张形势加剧,促使国家将对能效提出越来越高的要求。在能源领域,提高传热性能的研究和应用也逐渐变得紧迫。因此,节能对于一个建筑甚至是一个国家而言,都是一个被关注的焦点。此次毕业设计主要是对上海新飞公司办公楼进行一个冷热源设计。根据所给任务书的要求,需要对各楼层进行空调系统负荷计算、冷热源方案及设备的选择、机房布置、绘制图纸、最后完成论文的撰写。 48723

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
