Heat exchangers. Air cooled liquid coolers 'dry coolers'. Test procedure for establishing the performance

This document establishes a comprehensive framework for evaluating the performance characteristics of air-cooled liquid coolers, commonly referred to as dry coolers. It outlines specific methodologies and procedures necessary for conducting accurate performance measurements on heat exchange units operating with air as the cooling medium. The standard defines key parameters including thermal efficiency, pressure drop, and operational stability under varying environmental conditions. By adhering to these defined test protocols, manufacturers and testing laboratories can ensure consistent data collection and reliable comparison of equipment capabilities. The procedures cover setup requirements, measurement instrumentation, and calculation methods to determine heat transfer rates and flow rates. These guidelines facilitate the assessment of cooling capacity and energy consumption metrics essential for system design and optimization. The text provides technical specifications that align with broader European practices regarding thermal system evaluation, ensuring uniformity in testing approaches across different applications. This approach supports quality assurance in the manufacturing and deployment of industrial cooling solutions without relying on subjective assessment methods.
