越来越多的公司被评判为不仅仅是财务业绩，自愿承担的企业社会和环境责任趋向于超出标准要求的新水平。为了实现更高的企业能源效率和可持续性目标，更换供暖、通风和空调（HVAC）设备以提高能源效率是几个基石之一。在极热、多尘和腐蚀性的工业条件下，如沙特阿拉伯石油工业中遇到的情况下，实现这些目标变得更具挑战性，主要原因是暖通空调应用的临界性、缺乏确定最佳更换时间的标准化方法以及人为压低的能源价格。 为了达到有针对性的能源效率和最佳的更换时间框架，重要的是确定关键性能指标（KPI），工程师应考虑在执行暖通空调改造，考虑到严重的气候和腐蚀环境的经验在该地区。本研究介绍了一种定义关键绩效指标的系统方法，包括以下内容:设备年龄和类型、地理位置、实际能效比（EER）、故障率、剩余使用寿命、服务分类和设备制冷剂环境合规性。该研究还提供了生命周期成本示例，作为评估更换成本效益的决策支持工具。 作者希望这项研究将激励其他在类似条件下运营的组织采用同样的方法，并展示它们在能源效率和环境合规性方面的领导力。引用:ASHRAE论文:2015年ASHRAE年会，伊利诺伊州芝加哥

Companies are increasingly judged on more than financial performance, with voluntary corporate social and environmental responsibility trending to a new level beyond standard requirements. Replacement of heating, ventilation and air conditioning (HVAC) equipment for energy efficiency is one of several cornerstones for meeting higher corporate energy efficiency and sustainability targets. Meeting these targets under extremely hot, dusty and corrosive industrial conditions, such as those encountered in the petroleum industry in Saudi Arabia, becomes more challenging mainly due to HVAC application criticality, the lack of standardized approaches for determining the optimal time of replacement and the artificially low energy prices. To meet targeted energy efficiency and optimal replacement timeframes, it is essential to identify key performance indicators (KPIs) that an engineer should consider when performing HVAC retrofits that consider the severe climate and corrosive environment experience in the region. This study introduces a systematic approach to define KPIs that comprise the following: equipment age and type, geographical location, actual energy efficiency ratio (EER), failure rate, remaining service life, service classification and equipment refrigerant environmental compliance. The study also presents life cycle cost examples as a decision support tool to evaluate replacement cost effectiveness. The authors hope that this study will motivate other organizations operating under similar conditions to adopt the same approach and showcase their leadership in energy efficiency and environmental compliance.
