摘要
本文以广州市某办公楼转轮热回收系统为例,具体分析了排风全热回收对空调系统能耗的影响,分别计算了在空调季和采暖季的节能量及初投资静态回收年限,并计算了设置新排风旁通管系统节约的风机运行费用。得出结论:在广州地区,排风全热回收在空调季节能效果明显,采暖季节能能力有限,在系统中设置新排风旁通管时节能效果显著。
A wheel heat recovery system is applied to an office building in Guangzhou that was presented. The exhaust heat recovery system impacting on air-conditioning energy consumption was analyzed. Amount of energy saving and initial investment payback period in the cooling season and heating season were calculated. Comparing amount of energy saving and initial investment payback period with original system＇s, the fresh air exhaust bypass pipe system have more advantages than original system in energy conservation. The conclusions showed that the energy efficiency of exhaust heat recovery in the cooling season is higher than one in the heating season, and air-conditioning system equipped with new exhaust bypass pipe have a significant energy saving effect.
