某办公建筑空调制冷机房改造及节能率分析
Air conditioning refrigeration plant renovation and energy-saving rate analysis of an office building
摘要：
针对某办公建筑空调制冷机房改造前的运行状况,找出问题并针对性地提出改造方案;通过对节能量计算相关标准和研究的梳理,提出采用低、中、高不同负荷下典型相似日节能率和不同负荷率占比为依据计算全年节能率的工程方法。该项目改造后空调制冷机房系统全年能效比(EER)为4.5,全年节能率为44.8%,节能改造效果良好。
Abstract：
For the pre-renovation operational status of the air conditioning refrigeration plant in an office building, the problems are identified and the targeted renovation plans are proposed. By reviewing standards and research related to energy-saving calculation, an engineering method is developed to estimate the annual energy-saving rate based on the energy-saving rates of typical similar days under low, medium, and high load levels, combined with the proportions of different load rates. After the renovation, the annual energy efficiency ratio (EER) of the air conditioning refrigeration plant system reaches 4.5, with an annual energy-saving rate of 44.8%, demonstrating excellent energy-saving performance.
