The SIST EN 14825:2012 standard provides a comprehensive framework for the testing and rating of air conditioners, liquid chilling packages, and heat pumps with electrically driven compressors, specifically focused on their performance under part load conditions. Its scope encompasses factory-made units as defined in EN 14511 1, while explicitly excluding single duct, control cabinet, and close control units. One of the primary strengths of this European Standard is its detailed methodology for calculating reference seasonal energy efficiency (SEER and SEERon) and reference seasonal coefficient of performance (SCOP, SCOPon, and SCOPnet). These calculations are crucial for professionals in the HVAC industry, as they offer a reliable means to evaluate the efficiency of cooling and heating systems in real-world scenarios. Moreover, the inclusion of both calculated and measured values for assessment adds significant relevance and flexibility to the standard's application. By offering test methods to determine capacities, energy efficiency ratios (EER), and coefficients of performance (COP) during active mode at part load conditions, it ensures that the evaluation of performance is grounded in practical measurements. The provisions for assessing power consumption in various modes-thermostat off mode, standby mode, and crankcase heater mode-further enhance its applicability in energy management strategies. Additionally, the standard acts as a pivotal resource for calculating system energy efficiency for heating modes in specific heat pump systems, aligning with requirements set forth in standard EN 15316-4-2. This connection emphasizes the standard's role in promoting energy-efficient practices within the construction and HVAC sectors. Overall, the SIST EN 14825:2012 establishes a robust framework that bolsters the reliability and comparability of performance evaluations for cooling and heating systems. Its focus on part load conditions, seasonal performance metrics, and comprehensive testing methods renders it indispensable for professionals seeking to enhance energy efficiency in air conditioning and heating technologies.
