【摘要】 以气候差异较大的广州、哈尔滨住宅建筑为研究对象,利用De ST能耗模拟软件,分析了换气次数与传热系数36种不同组合工况对住宅建筑冷、热负荷的影响。结果表明:对寒冷住宅地区,当传热系数为0.16,换气次数介于2.0～2.5次/h时,对冷负荷影响最大,当传热系数为0.6,换气次数介于2.0～2.5次/h时,对热负荷影响最大;对温暖住宅地区,当传热系数为0.2,换气次数介于4.0～4.5次/h时,对冷负荷影响最大,当传热系数为0.8,换气次数介于3.4～4.0次/h时,对热负荷影响最大。换气次数对冷负荷影响较大,两者对热负荷影响相差较小。更多还原

【Abstract】 Taking the residential buildings in Guangzhou and Harbin with different climate differences as research objects, the DeST energy consumption simulation software is used to analyze the effects of 36 different combinations of ventilation times and heat transfer coefficients on the cold and heat load of residential buildings. The results show that, for cold regions, when the heat transfer coefficient is 0.16 and the number of air exchanges is between 2.0 and 2.5 times/h, the effect on the cooling load is the greatest; when the heat transfer coefficient is 0.6 and the number of air changes is between 2.0 and 2.5 times/h, the heat load has the greatest influence; for warm areas, when the heat transfer coefficient is 0.2 and the number of air exchanges is between 4.0 and 4.5 times/h, the heat load has the greatest influence; when the heat transfer coefficient is 0.8, the number of air changes is 3.4～4.0 times/h, the greatest impact on the heat load. The number of air changes has a great influence on the cooling load, and the difference between the two has little effect on the heat load.更多还原
