Overview

This document (EN 16798-9:2017) has been prepared by Technical Committee CEN/TC 156 "Ventilation for buildings". The responsible German committee is Working Committee NA 041-05-02 AA "Energetische Bewertung von raumluft- und klimakältetechnischen Anlagen" ("Energy efficiency of ventilation/air conditioning and refrigeration systems") at DIN Standards Committee Heating and Ventilation Technology and their Safety (NHRS). This European Standard covers the energy performance calculation of complete cooling systems. It gives a calculation method that defines how to collect the cooling energy requirements from the thermal zones and from the air handling units connected to a distribution system, and how to aggregate multiple distribution systems to an overall system energy requirement. It incorporates the calculation of the emission and distribution losses and auxiliary energy. The required cooling energy to be extracted by the cooling generation system is calculated, and the cooling energy storage is considered. It gives a method on how to dispatch the cooling energy provided by the cooling generation to different distribution systems, and possible priorities are considered. This European Standard defines energy performance indicators for cooling systems.
