DIN EN 16798-9:2015-01

This standard covers the energy performance calculation of complete cooling systems. It gives a calculation method which 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 integrates 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, considering cooling energy storage. It gives a method on how to dispatch the cooling energy provided by the cooling generation to different distribution systems, considering possible priorities. This standard defines technical system related energy performance indicators for cooling systems.
