What is this standard about?
This European Standard covers the calculation of the operational parameters and the energy consumption of cooling generation systems. The cooling generation consists of:
— cooling generators like compression and absorption chillers;
— other (generic) generator types such as ground or surface water or direct use of ground heat from boreholes; and
— different types of heat rejection (dry, wet, hybrid with outdoor air, other sink types).
The methods cover:
— the possibility of heat recovery of heat to be rejected for the use of heating and/or domestic hot water production, through the use of an interface to the M3-1 standard; and
— a multi generator calculation.
The document does not cover the cooling emission, distribution and storage systems, which are covered by the Module M4-5, M4-6 and M4-7 standards, respectively. It is directly connected to the general part of the cooling systems, the M4-1 standard.
