摘要
以哈尔滨、北京、成都三个地区为例,分析了提高办公建筑气密性对采暖和空调能耗的影响。研究发现,在满足室内空气品质的前提下,适当的减少换气次数,提高建筑气密性,对全年空调能耗有一定的节能效果,对全年采暖能耗降低显著,且在不同地区的影响也有差异,即在全年室外平均气温较低的地区,改变换气次数对建筑能耗的影响更大。因此,减少建筑物空气渗透量能耗是建筑节能的一个重要方面。
Taking Haerbin, Beijing and Chengdu as case studies, the influence on heating and cooling energy consumption is analyzed by increasing the tightness of office building. The research shows that： a） under the premise to meet the indoor air quality, reducing the number of ventilators and increasing the airtightness of buildings properly have certain energy-saving effect on the annual consumption of energy for air-conditioning and also reduce the annual consumption of energy for heatingsigniflcantly; b） this influence on energy consumption is different in different regions. Especially in the regions with a lower annual average outdoor temperature, changing the number of ventilators has a greater impact on building energy consumption, Therefore, it is an important approach to building energy conservation by reducing the energy consumption of building air permeation amount.
