摘要
本文以重庆气象条件为代表,利用能耗模拟软件DeST-c对重庆市某办公楼进行能耗模拟分析,分别模拟了在不同通风状态下的建筑自然室温、建筑冷热负荷及空调系统能耗的变化情况,并分析了夜间通风的节能效果。研究表明重庆地区合理通风对降低建筑自然室温有一定的作用;建筑空调能耗较采暖能耗对通风的敏感性指标显著;夜间通风的节能效果显著,但是最大节能量不是无限的。
Taking Chongqing meteorological condition as the background, this article simulates the nature indoor temperature, cool （hot） load and energy consumption of air conditioning system in an office building using simulative software DeST-c under different ventilated states, and analyzes the energy efficiency effect of nightly ventilation. The research indicates that reasonable ventilation can reduce the nature indoor temperature to some degree, and the ventilated sensibility of air conditioning is more remarkable than that of heating, and the energy efficiency effect of nightly ventilation is remarkable, but the energy efficiency potential is limited.
