一 前言 太阳能热水器已经在我国得到广泛应用,但大多应用在广大农村地区和城市低层建筑上,而且在建筑上的应用以单体太阳能热水器居多,由于观念、政策、技术和设计等方面的原因,在高层建筑上安装大型太阳能热水系统,仍然存在很大障碍.笔者亲自参与了某高层建筑太阳能热水集热系统的设计工作,笔者将从方案选择及供水方案进行介绍,以期在我国大力倡导节能减排的今天,对高层建筑太阳能热水集热系统的推广有所帮助. 相似文献

According to statistics and field investigation, the energy consumption situation and reality of commercial building is described in this paper. As the first step of large-scale public building energy efficiency supervision system encouraged by central government of China, the energy consumption of several typical commercial buildings and public buildings was analyzed in detail. The main contents of investigation are as follows: basic information of building, operational record of energy consumption equipment, energy consumption of indoor equipments, energy-efficiency assessment of energy consumption systems and equipments, investigation of behavior energy saving, etc. On this basis further analysis and diagnosis including indoor thermal and humid environment, operation state of air-conditioning water system, operation state of air-conditioning duct system and operation management of air-conditioning system were implemented. The results show that the most energy consumption of buildings in this city is commercial buildings, which can reach to about 240 W/m2 per year. Further analysis tells that air conditioning systems play the major role of building energy consumption, and building energy saving has great potential in this city. In this paper, the ways of diagnosis work for building energy consumption are also described and discussed. Reasonable test, diagnosis and analysis are meaningful for building energy efficiency retrofit and management. 相似文献

This study deals with the performance of different air-conditioning strategies for achieving the target of nearly/net zero energy in a medium-scale building under various environmental conditions. In particular, vapour compression (VC), vapour absorption (VA), and integration of radiant cooling technology are analysed using renewable energy resources and solar photovoltaic (PV)-based electricity. Four different kinds of air-conditioning configurations are considered: VC-based, VA-based, VC-radiant air-conditioning technology with VC dedicated outdoor air system (DOAS) and VA radiant air-conditioning technology with VC-DOAS. Numerical model validations with the benchmark standards are done for VC- and VA-based systems. In particular, annual electric consumption, electricity generation, thermal load generation among all configurations, emissions and solar fractions are studied. The present study shows that target of nearly/net zero-energy building can be achieved in an efficient manner through radiant VC-based system with VC-DOAS for hot-dry and composite (ie, hot-dry with higher humidity) environment conditions. However, for warm-humid environment, complete net zero is not possible, but up to 74% of net zero target can be assured with VC-based radiant and DOAS. With respect to the conventional VC-based system, the payback period assessment for the most suitable nearly/net zero building cooling system varies in the range of 5-9 years, depending on the environmental conditions. 相似文献

There are 17 green building standards (including those under development) at country level and another 50 or more at provincial level in China. Based on background and status overview of green building standards, problems are analyzed. It is followed by a systemic scheme for green building standard system, which includes 3 layers of basic, general and specialized standards, and its development planning as well. Some suggestions are proposed for green building standards development in this paper. 相似文献
