31、ing systems in buildings”, the secretariat of which is held by DIN. This document supersedes EN 15316-4-2:2008. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2017, and conflicting nation

32、al standards shall be withdrawn at the latest by October 2017. The revision keeps the main principles of the calculation unchanged but the structure of the document was changed. Informative content was removed to the accompanying technical report CEN/TR 15316-6-2. The provisions cover also other ene

33、rgy carriers than heat now. The values may be altered in a national annex. Calculation methods to determine energy source indicators like the renewable energy ratio have been added. The main changes compared to EN 15316-4-2:2008 are: a) type of heat pumps are now limited to hot water production at t

34、he output of the condenser; b) informative content was removed to the accompanying technical report CEN/TR 15316-6-2; c) calculation for performance of the heat pumps at different conditions is based on interpolation provisions; d) input data for energy performance of the heat pumps are based on par

35、t load and/or full load information; e) Annex A contains a template for the data and parameters used in the standards and Annex B a set of default values. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. Attention is dra

36、wn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

BS EN 15316-4-2:2017EN 15316-4-2:2017 (E) 5 Introduction This European Standard is part of a series of standards aiming at international harmonization of the methodology for the assessment of the

39、energy performance of buildings, called “set of EPB standards”. All EPB standards follow specific rules to ensure overall consistency, unambiguity and transparency. All EPB standards provide a certain flexibility with regard to the methods, the required input data and references to other EPB standar

40、ds, by the introduction of a normative template in Annex A and Annex B with informative default choices. EPB standards deal with energy performance calculation and other related aspects (like system sizing) to provide the building services considered in the EPBD. CEN/TC 228 deals with heating system

41、s in buildings. Subjects covered by CEN/TC 228 are: energy performance calculation for heating systems; inspection of heating systems; design of heating systems; installation and commissioning of heating systems. This standard specifies to take into account the energy performance of heat pump system

42、s used for domestic or heating purpose. For the correct use of this standard, Annex A is to be used to specify the choices with the required input data. Default values are presented in Annex B. In case the standard is used in the context of national or regional legal requirements, mandatory choices

43、may be given at national or regional level for such specific applications, in particular for the application within the context of EU Directives transposed into national legal requirements. These choices can be made available as National Annex or as separate (e.g. legal) document. It is expected, if

44、 the default values and choices in Annex A are not followed due to national regulations, policy or traditions, that: either the national standardization body will consider the possibility to add or include a National Annex in agreement with the template of Annex A. or the national or regional author

45、ities will, in the building regulations, reference the standard and prepare data sheets containing the national or regional choices and values, in agreement with the template of Annex A. This updated standard covers hourly, monthly, annual time-steps and temperatures classes (bin method). BS EN 1531

46、6-4-2:2017EN 15316-4-2:2017 (E) 6 1 Scope This European Standard covers heat pumps for space heating, heat pump water heaters (HPWH) and heat pumps with combined space heating and domestic hot water production in alternate or simultaneous operation, where the same heat pump delivers the heat to cove

47、r the space heating and domestic hot water heat requirement. The standard provides a calculation method under steady conditions that corresponds to one calculation step. The results of this calculation are incorporated in larger building models and take in account the influence of the external condi

48、tions and building control that influence the energy requirements for heating supplied by the heat pump system. The scope of this part is to standardize the: required inputs; calculation methods; required outputs Generation for space heating and domestic hot water production of the following heat pu

49、mp systems, including control of: electrically-driven vapour compression cycle (VCC) heat pumps; combustion engine-driven vapour compression cycle heat pumps; thermally-driven vapour absorption cycle (VAC) heat pumps, using combinations of heat source and heat distribution listed in Table 1.
