1 Scope
This European Standard covers energy performance calculation of water based distribution
systems for space heating, space cooling and domestic hot water.
This European Standard deals with the heat flux from the distributed water to the
space and the auxiliary energy of the related pumps.
The heat flux and the auxiliary energy for pumps can be calculated at any time-step
(hour, month and year). The input and output data are mean values of the time step.
Instead of calculating the energy performance of water based distribution systems
it is also possible to use measurements as long as they are following the timesteps
of the whole performance calculation or can divided in those timesteps.
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 EN ISO 52000‑1:2017.
NOTE 1 In CEN ISO/TR 52000‑2:2017 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 2 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.
