Abstract

The commissioning processes of new buildings, existing buildings and continuous commissioning have been important tools to identify low performance and high energy consumption problems, contributing to its solutions, energy conservation and the research of more efficient systems. Considering the important participation of air conditioning systems in the energy consumption of buildings, this article presents the proposed methodology in study based on the recommissioning concepts to evaluate the operational and energy performance of these systems. The methodology is demonstrated through its application at an airport air conditioning system in the city of Rio de Janeiro. The operational data collected daily are used to demonstrate the phases of the proposed methodology. The evaluation of the system was performed by the process capability analysis, operational mode in use and performance coefficient (COP). As result, improvement opportunities were identified, with COP growth from 5.95 to 6.84 and reduction of energy consumption on chillers by up to 13.0%. Finally, the results showed in its comparison with the reference values, raised in the bibliography, allowed to conclude that the proposed methodology is suitable for direct application in similar systems, such as shopping malls and airport terminals. With some adaptation it can be expanded to other ventures.

机场空调系统评估的重新调试方法

新建筑、现有建筑和连续调试的调试过程是识别低性能和高能耗问题的重要工具，有助于解决问题、节约能源和研究更高效的系统。考虑到空调系统在建筑能耗中的重要作用，本文提出了基于重新调试概念的研究方法，以评估这些系统的运行和能源性能。该方法通过在里约热内卢市机场空调系统的应用进行了验证。每天收集的业务数据用于演示拟议方法的各个阶段。通过过程能力分析、使用工况和性能系数(COP)对系统进行评价。结果，发现了改进的机会，COP从5.95增长到6.84，制冷机的能耗减少了13.0%。最后，将其与参考文献中提出的参考值进行比较的结果表明，所提出的方法适合直接应用于类似的系统，例如购物中心和机场航站楼。经过一些调整，它可以扩展到其他企业。
