以广州某办公建筑集中空调系统为典型案例,基于集中空调系统的制冷系数、能效比等指标,从工艺和设备方面,提出办公场所集中空调系统的不同改造方案,对比不同方案的节能潜力,并基于层次分析法给出各个优化方案的权重。结果表明:采用水泵和压缩机变频技术并提高室内设定温度的节能潜力最大;合理确定设计运行参数,可以有效节约空调系统用能。
Taking a central air-conditioning system of an office building in Guangzhou as a typical case, this paper proposes different schemes of central air-conditioning system for office space based on the cooling coefficient and energy efficiency ratio of the central air-conditioning system and compares the energy-saving potential of different schemes The weight of each optimization scheme is given based on AHP. The results show that the energy saving potential of using pump and compressor frequency conversion technology and increasing the indoor set temperature is the largest. Reasonably determining the design operating parameters can effectively save the air conditioning system energy consumption.
