建筑空调复合节能技术初探

Study on the Compound Energy-saving Technology of Air Conditioning in Buildings

外墙热工性能对空调能耗有重要意义,空调排风所损失的能量也很可观,本文提出在建筑外墙的内部设置空气层作为空调系统排风通道,通过排风与墙体进行热交换,回收利用空调排风所带能量,可望在降低外墙传热造成的能耗损失、回收空调排风所带走的能量、降低室外环境温度变化与室内热舒适性之间相关性等三个方面获得益处。

The thermal characteristics of external wall has important meaning to the energy consumption of the air conditioning system. The energy loss of exhaust air should not be ignored. This paper puts forward a new concept, that is, the air layer which is set in the inside of external walls in a building as the passage of the air conditioning exhaust. By the heat exchange between the exhaust air and the wall body, the energy of the exhaust air is recovered and reutilized. There are three advantages. First, to lower the energy loss of the heat exchange through the wall. Second, to recover a part of the energy that the air conditioning exhaust takes away. Third, to lower the correlation between the outdoor temperature fluctuation and indoor thermal comfort.
