某办公建筑空调系统变风量改造

VAV air conditioning system reform for an office building

原空调系统能耗高 ,运行噪声大 ,人工调节控制 ,影响正常工作 ;经过变风量改造后 ,系统运行稳定可靠 ,能耗降低约 1 / 2 ,机组A声级噪声均小于 60dB ,改造投资在 2～ 3年内即可回收。

The former air conditioning system is of lower energy efficiency and high noise level, worsening occupant working conditions. After reforming to a VAV system, it operates steady and reliable. It can reduce energy consumed to nearly a half. The noise level is lowered to under 60 dB. The reform investment will be recovered in 2 to 3 years.
