针对该工程集中式空调系统由于机组容量配置过大而造成的冷源能量过剩问题进行了改造,使两幢楼原本各自独立的冷源系统在负荷需求量较小时合二为一,即用一幢楼的冷源设备来满足两幢楼的负荷需求,实现了较为节能的供冷方案。投资回报分析结果表明,该方案年平均节省电能8.1%,一年内即可收回投资。 In view of the problem of over-energy of cold source caused by excessive capacity of the unit in the centralized air-conditioning system of the project, the two independent cold source systems of the two buildings are combined into one when the load demand is small, Building cold source equipment to meet the two buildings of the load demand, to achieve a more energy-efficient cooling program. The result of ROI analysis shows that the scheme saves an average of 8.1% of the electric energy annually and can recover the investment within one year.
