Abstract
Industrial energy efficiency is a critical factor for the success of energy transition efforts. That demand enhances industry concerns on energy awareness and management, along with its economic benefits, but energy efficiency opportunities are not yet broadly exploited. Heat, Ventilation, and Air conditioning (HVAC) is a significant energy consumer at most industrial facilities and holds relevant energy savings potential, often neglected by managers. In this context, this paper searches to propose a direct and standardized method to evaluate the performance of industrial air conditioning systems based on regular and easy to assess information from the installation. Air-conditioning systems are decomposed into installed equipment factors and system operation energy factors, which are evaluated based on quantitative data from the literature research. The best available techniques (BAT) approach is applied, along with considerations from national regulations concerning efficiency levels of air conditioning equipment and technical literature. The identified equipment factors are the energy efficiency label and the application of supporting systems. The operation factors identified are the operating temperature, proper maintenance, and application of system automation measures. The energy factors' information is assembled into a set of conditions and results in levels of performance, defined by Key Performance Indicators (KPIs). The final system efficiency is calculated by the indirect method, considering each factor condition, and correlated with the available benchmark, allowing for a suitable diagnosis of the energy performance. The evaluation outcomes are demonstrated by the application in three hypothetical cases, indicating that it enables the comparison between different air-conditioning system configurations performances and supports the identification of improvement opportunities on air-conditioning systems. It is expected that decision-makers from different industries will be able to properly identify their main priorities and define energy savings strategies.
