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.Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1:2015.NOTE 1In FprCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying Technical Reports that are published or in preparation.NOTE 2The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
