摘要
对冬季夜间建筑物外围护结构得热进行了理论分析,并进行逐时热负荷计算,结果表明在冬季夜间供暖空调标准工况下,没有考虑夜间辐射的建筑物热负荷要比实际所需负荷约小8.4%,对于节能保温较好的墙体,夜间辐射所产生的热负荷要比保温效果差的墙体小,指出供暖空调系统在冬季夜间运行时有必要考虑这部分负荷。
It makes theory analysis on the heating of architectural fender structure in winter night and the calculation on heat load by time. The solution is proof that the architectural heat load that not considering the night radiation is 8, 4 % less than the real needed load in the standard working situation of air-conditioning in winter night and the heat load generated of night radiation is less than the wall of worse heat preservation, and points out that it is necessary of considering the load of the operation of heating air-conditioning in winter night.
