| 摘 要： | 本文分析了夏热冬暖地区公共建筑空调新风负荷特征，研究了不同排风热回收模式下的节能效果。结果表明，当采用全热回收模式时，新风负荷降低60％以上，建筑空调冷负荷降低18％～23％；而采用显热回收模式时，新风负荷降低5％-20％，建筑空调冷负荷仅降低8％。可见，夏热冬暖地区公共建筑空调排风全热回收模式具有较好的节能效益。

| Abstract: | In this paper, the characteristics of fresh air cooling load in public buildings in hot summer and warm winter area were analyzed, and energy saving effects under different exhaust air heat recovery modes were investigated. The results indicated that under the total heat recovery mode, fresh air cooling load could reduced up to 60%, and the total cooling load could reduced 18% - 23%, while under the sensible heat recovery mode, the correspending values were only 5 % - 20% and 8 %. Hence, it was concluded that the exhaust air total heat recovery mode of air-conditioning system in public buildings had better energy efficiency benefit in hot summer and warm winter area. |
