Abstract

Detailed demand profiles for the residential sector are an important prerequisite for the improvement of building energy efficiency and the development of polygeneration systems. Therefore, the aim of this paper is to provide a generic pattern for each energy demand required for a single-family dwelling. The data of electricity, domestic hot water and freshwater were obtained through literature reported methods of demand profile estimation, whereas heating and cooling have been estimated by TRNSYS software simulation. All methods provide energy consumption profiles with 1-hour time step along 1-year period. Daily, weekly and yearly results are presented. The total dwelling consumption amounts to 3,866 kWh/y of electricity, 941 kWh/y of heating, 1,450 kWh/y of cooling, 41 m/y or 2,090 kWh/y of domestic hot water and 110 m/y of freshwater. Primary energy saving can achieve up to 13,917 kWh/y in case of renewable energy use and a higher comfort level is felt by the users during summer.

单户住宅的住宅部门能源需求估算：动态模拟和能源分析

住宅部门的详细需求概况是提高建筑能效和发展多联产系统的重要前提。因此，本文的目的是为单户住宅所需的每种能源需求提供一个通用模式。电力、生活热水和淡水的数据是通过文献报道的需求剖面估计方法获得的，而供暖和制冷是通过TRNSYS软件模拟估计的。所有方法都提供了沿1年周期的1小时时间步长的能耗概况。提供每日、每周和年度结果。住宅总用电量为3866千瓦时/年，供暖941千瓦时/日，制冷1450千瓦时/月，生活热水41米/年或2090千瓦时/天，淡水110米/年。在使用可再生能源的情况下，一次能源节约可达到13917千瓦时/年，用户在夏季可以感受到更高的舒适度。
