PD CEN/TR 15316-6-9:2017CEN/TR 15316-6-9:2017 (E) 5 Introduction The set of EPB standards, technical reports and supporting tools: In order to facilitate the necessary overall consistency and coherence, in terminology, approach, input/output re
28、lations and formats, for the whole set of EPB-standards, the following documents and tools are available: a) a document with basic principles to be followed in drafting EPB-standards: CEN/TS 16628, Energy Performance of Buildings Basic Principles for the set of EPB standards 1; b) a document with de
29、tailed technical rules to be followed in drafting EPB-standards; CEN/TS 16629, Energy Performance of Buildings Detailed Technical Rules for the set of EPB-standards 2; c) the detailed technical rules are the basis for the following tools: 1) a common template for each EPB-standard, including specifi
30、c drafting instructions for the relevant clauses; 2) a common template for each technical report that accompanies an EPB standard or a cluster of EPB standards, including specific drafting instructions for the relevant clauses; 3) a common template for the spreadsheet that accompanies each EPB stand
31、ard, to demonstrate the correctness of the EPB calculation procedures. Each EPB-standards follows the basic principles and the detailed technical rules and relates to the overarching EPB-standard, EN ISO 52000-1:2017. One of the main purposes of the revision of the EPB-standards is to enable that la
32、ws and regulations directly refer to the EPB-standards and make compliance with them compulsory. This requires that the set of EPB-standards consists of a systematic, clear, comprehensive and unambiguous set of energy performance procedures. The number of options provided is kept as low as possible,
33、 taking into account national and regional differences in climate, culture and building tradition, policy and legal frameworks (subsidiarity principle). For each option, an informative default option is provided (Annex B). Rationale behind the EPB technical reports: There is a risk that the purpose
34、and limitations of the EPB standards will be misunderstood, unless the background and context to their contents and the thinking behind them is explained in some detail to readers of the standards. Consequently, various types of informative contents are recorded and made available for users to prope
35、rly understand, apply and nationally or regionally implement the EPB standards. If this explanation would have been attempted in the standards themselves, the result is likely to be confusing and cumbersome, especially if the standards are implemented or referenced in national or regional building c
36、odes. Therefore each EPB standard is accompanied by an informative technical report, like this one, where all informative content is collected, to ensure a clear separation between normative and informative contents (see CEN/TS 16629 2): - to avoid flooding and confusing the actual normative part wi
37、th informative content, PD CEN/TR 15316-6-9:2017CEN/TR 15316-6-9:2017 (E) 6 - to reduce the page count of the actual standard, and - to facilitate understanding of the set of EPB standards. This was also one of the main recommendations from the European CENSE project 4 that laid the foundation for t
38、he preparation of the set of EPB standards. PD CEN/TR 15316-6-9:2017CEN/TR 15316-6-9:2017 (E) 7 1 Scope This Technical Report refers to EN 15316-4-8:2017, module M3-8.8. It contains information to support the correct understanding, use and national adaptation of EN 15316-4-8:2017. This Technical Rep
39、ort does not contain any normative provision. The scope of EN 15316-4-8:2017 includes three categories of products: air heating systems means a system with one or more warm air generators for heating purpose. The hot air may be diffused in the installation space from the generator or distributed via
40、 a ductwork. overhead radiant heating systems, means systems using gas and designed to provide heat into the installation room. Radiation may be generated directly by the flame (overhead radiant luminous heaters) or by circulation of flue gas in a ductwork installed near the ceiling (overhead radian
41、t tube heaters). stoves and local heaters means local devices that provide heat by transferring the heat generated by combustion into the surrounding environment. The typical devices are shown in Figures 1 to 4. Figure 1 Warm air generator for an air heating system PD CEN/TR 15316-6-9:2017CEN/TR 153

This enables flexible references (e.g. to national documents where necessary for local application) and use outside the CEN environment. 3 Terms and definitions Fo
47、r the purposes of this document, the terms and definitions given in EN ISO 7345:1995, EN ISO 52000-1:2017 and EN 15316-4-8:2017 apply. NOTE 1 No new definition is given in this Technical Report. NOTE 2 During public enquiry, it was commented that the term “stove” is not appropriate. The correct term
48、, which is used in the product standard is “local heaters”, meaning a heater which is not attached to any distribution system. The term “stove” survived in the title, as a synonym of “local heater” because the title of a standard cannot be changed during the drafting process. 4 Symbols and subscript
49、s 4.1 Symbols For the purposes of this document some special symbols are defined in EN 15316-4-8:2017: is used for losses factors. They are expressed as a percentage, so the usual range is 0 to 100. Some negative values or values beyond 100 are expected when dealing with condensing heaters. is used for loaf factors. They are expressed in per unit, so the usual range is 0 to 1. Typically is a value that changes at each calculation interval depending on load. has been used for the vertical tempe
