摘要

以夏热冬冷地区的普通住宅公寓和低能耗住宅公寓为例

定义温度向上和向下两种灵活性调节事件

利用DesignBuilder对比分析建筑本体固有的保冷能力

量化建筑在供冷季的能源灵活性潜力。结果表明：在不影响人体热舒适的前提下

低能耗住宅在向下调节中增加的冷量远低于普通住宅

最优时长为12:00—18:00。通过向下调节

低能耗住宅的可再生能源自给率达到79.8%

远超普通住宅的37.2%。经济性分析显示

低能耗住宅在向上和向下调节中均有收益

一天内节省电费分别为129元和105元。

Abstract

Assessing the energy flexibility potential of buildings during the cooling season

by taking an ordinary residential apartment and a low-energy residential apartment in the hot summer and cold winter zone as case studies. Two types of flexible temperature adjustment events are defined

namely

upward and downward adjustment. Then

DesignBuilder is used to compare and analyze the inherent cooling capacity of the building’s thermal mass. The results show that

without affecting human thermal comfort

the additional cooling load in the downward adjustment of the low-energy residential apartment is much lower than that of the ordinary residential apartment

with the optimal period being from 12:00 to 18:00. Through downward adjustment

the self-sufficiency rate of solar energy in the low-energy residential apartment reaches 79.8%

far exceeding that of the ordinary residential apartment at 37.2%. Economic analysis indicates that the low-energy residential apartment yields benefits in upward and downward adjustments

saving electricity costs by 129 yuan and 105 yuan per day.
