However, attention is drawn to the fact that during the development of this European Standard, the UK voted against its approval as a European Standard The UK voted against this standard on the grounds that it was conside

5、red disproportionate to the essential requirements of the EU Energy Performance of Buildings Directive (2002/91/EC), which it supports.

27、N 15316-4-2:2008) has been prepared by Technical Committee CEN/TC 228 “Heating systems in buildings”, the secretariat of which is held by DS. 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 Decemb

28、er 2008, and conflicting national standards shall be withdrawn at the latest by December 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent

29、 rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/343), and supports essential requirements of EU Directive 2002/91/EC on the energy performance of buildings (EPBD). It forms part of a series of standar

30、ds aimed at European harmonisation of the methodology for calculation of the energy performance of buildings. An overview of the whole set of standards is given in CEN/TR 15615 13. The subjects covered by CEN/TC 228 are the following: design of heating systems (water based, electrical, etc.); instal

31、lation of heating systems; commissioning of heating systems; instructions for operation, maintenance and use of heating systems; methods for calculation of the design heat loss and heat loads; methods for calculation of the energy performance of heating systems. Heating systems also include the effe

32、ct of attached systems such as hot water production systems. All these standards are systems standards, i.e. they are based on requirements addressed to the system as a whole and not dealing with requirements to the products within the system. Where possible, reference is made to other European or I

33、nternational Standards, a.o. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the system requirements. The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system a

34、nd not specifying shape, material, dimensions or the like. The guidelines describe ways to meet the requirements, but other ways to fulfil the functional requirements might be used if fulfilment can be proved. Heating systems differ among the member countries due to climate, traditions and national

35、regulations. In some cases requirements are given as classes so national or individual needs may be accommodated. In cases where the standards contradict with national regulations, the latter should be followed. BS EN 15316-4-2:2008EN 15316-4-2:2008 (E) 5 EN 15316 Heating systems in buildings Method

BS EN 15316-4-2:2008EN 15316-4-2:2008 (E) 6 Introduction This European Standard is part of a series of standards on the methods for calculatio

41、n of system energy requirements and system efficiencies. The framework for the calculation is described in the general part (EN 15316-1 9). The energy performance can be assessed by determining either the heat generation sub-system efficiencies or the heat generation sub-system losses due to the sys

42、tem configuration. This European Standard presents methods for calculation of the additional energy requirements of a heat generation sub-system in order to meet the distribution sub-system demand. The calculation is based on the performance characteristics of the products given in product standards

43、 and on other characteristics required to evaluate the performance of the products as included in the system. Product data, e.g. heating capacity or COP of the heat pump, shall be determined according to European test methods. If no European methods exist, national methods can be used. This method c

44、an be used for the following applications: judging compliance with regulations expressed in terms of energy targets; optimisation of the energy performance of a planned heat generation sub-system, by applying the method to several possible options; assessing the effect of possible energy conservatio

45、n measures on an existing heat generation sub-system, by calculating of the energy use with and without the energy conservation measure. Only the calculation method is normative. The user shall refer to other European Standards or to national documents for input data. Additional values necessary to

46、complete the calculations are to be given in a national annex, if no national annex is available, default values are given in an informative annex where appropriate. 1 Scope This European Standard covers heat pumps for space heating, heat pump water heaters (HPWH) and heat pumps with combined space

47、heating and domestic hot water production in alternate or simultaneous operation, where the same heat pump delivers the heat to cover the space heating and domestic hot water heat requirement. The scope of this part is to standardise the: required inputs, calculation methods, resulting outputs, for

48、heat generation by the following heat pump systems, including control, for space heating and domestic hot water production: electrically-driven vapour compression cycle (VCC) heat pumps, combustion engine-driven vapour compression cycle heat pumps, BS EN 15316-4-2:2008EN 15316-4-2:2008 (E) 7 thermal

49、ly-driven vapour absorption cycle (VAC) heat pumps, using combinations of heat source and heat distribution as listed in Table 1.
