18、due to a lot of “textbook” information. This resulted in flooding and confusing the normative text. A huge amount of informative contents shall indeed be recorded and available for users to properly understand, apply and nationally adapt the EPB standards. The detailed technical rules CEN/TS 16629 a
19、sk for a clear separation between normative and informative contents: to avoid flooding and confusing the actual normative part with informative content; to reduce the page count of the actual standard; to facilitate understanding of the package. Therefore each EPB standard shall be accompanied by a

34、egrated functions applied to all parts of heating system taking account predictable or detected occupancy and other events as smart metering information, . etc. 5.2 Partitioning control heating zones in buildings For efficiently control heating, the heating power shall satisfy heat demand. For this
35、purpose, heating power is compensated by outside temperature and scheduled for intermittent heating in relation with conditions of use. For efficiency of control systems, the heating system distribution building shall be partitioned into zones or spaces with uniform conditions of use, NOTE Partition
36、ing of heating systems described on prEN ISO 52000-1:2015, 9, D.2, D.3, may usefully be applied for the design of heating systems. BAC heating control system shall have multiple controls and intermittent scheduling adapted to zones or elementary spaces conditions of use. Special attention shall be d
37、one to keep watch for update set points and schedulers to real conditions of use and needs, during exploitation. For satisfy these indications size of zones shall be limited. NOTE An indication is given in EN 1531623:2007, A2: limit zones area to 1 000 m2. 5.3 Generation, distribution, emission cont
38、rol 5.3.1 General As a general rule, heating control systems consists to integrate many functions applied to central (generation, storage), zone (distribution) and room (emission) parts of heating systems. OTC control and OSS and complementary integrated functions specified by prEN 12098-3:2015 fulf
39、il items in prEN 15232-1:2015, Table 4, 1.3. NOTE Better control and scheduling of heating systems imply a data communication network linking control devices for integration of these functions and other technical building management capabilities for energy performance. 5.3.2 Generation Generation pa
40、rt consists to switch on-off or to modulate the available heating power. For this part, objectives of control functions are: the lowest heating power satisfying the higher zone demand the longest reduced (or stop) heating power satisfying the shorter reduced (or stop) heating zone period. For single
41、 zone distribution, generation control take account thermal characteristics and conditions of use (see prEN 52000-1:2015, Clause 9, D.2, D.3). 5.3.3 Distribution Distribution parts are controlled in the same way as for generation, switching or modulating available electrical power, for same objectiv
42、es. PD CEN/TR 12098-7:2016 CEN/TR 12098-7:2016 (E) 9 5.3.4 Emission The aim of individual control consist to adapt conditions of operation (individual room temperature set point and scheduling), to consumers needs (see prEN 15232-1:2015, Figure 1) and to compensate room heat gains, reducing heating
43、for comfort and energy saving. Individual room temperature control performance doesnt depend only of individual controllers; it depends also of the available heating power limited by central (generation, distribution) control, mainly for these cases: Emitters are not equipped with efficient electron
44、ic individual controllers (conform to prEN 15500-1:2015). Users are not encouraged to adapt the set point of their room temperature controller considering their comfort needs related to energy consumption. Heated room or space doesnt permit to measure a representative temperature for individual (clo
45、sed loop) control, e.g.: entrance, corridor, reception hall, exhibition hall, atrium, Emission control is operated only by the central power control (generation, distribution parts). Whatever, for avoid energy wasting by unusual use, inattentive settings or defaults of room controllers, the central
46、OTC control limit the available heating power. EXAMPLE Room temperature able to be reached by OTC controlled available power may be limited to 22 C, room controller reduce this level, reducing power emitter.
