PD CEN/TR 12098-8:2016CEN/TR 12098-8:2016 (E) 4 Introduction The CENSE project, the discussion between CEN and the Concerted action highlighted the high page count of the entire package due to

15、 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 ask for

16、 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 an info

17、rmative technical report, like this one, where all informative content is collected.

30、p scheduling of heating systems Energy performance of heating systems involves suited BAC functions. Among them, switching on-off energy services related to predictable use of rooms, zones or buildings is the basic, simplest and more effectiveness function. Clock scheduling intermittences is complet

31、ed with derogation functions for override programmed periods and with timer function for single periods. These added functions started manually or automatically allow satisfying unexpected needs. Properly energy managed buildings involve a large number of scheduled switching, punctuating running of

32、each energy equipment, in all parts of heating systems and other technical services for satisfy comfort needs and minimize energy consumption. This lot of individually programmed clocks distributed in buildings imply to link schedulers on a BAC or management system by the way of a digital network. F

33、or efficiently control heating: The heating system of the building shall be divided into spaces or zones with uniform conditions of use (see prEN ISO 52000-1:2015, D.2, D.3), BAC heating control system shall have multiple clock scheduling adapted to these conditions of use, Special attention shall b

34、e done to keep watch for update schedulers to real conditions of use, during exploitation. 5.2 Partitioning control heating zones in buildings For efficiently control heating, the flow temperature level of generation and distribution system shall satisfy heat demand. For this purpose, flow temperatu

35、re is 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, Partitioning of heating systems described on prEN ISO 52000-1:2015, Claus

36、e 9, D.2, D.3, may usefully be applied for the design of heating systems. The zone partitioning of the building shall take account thermal characteristics of emitters (all identical emitters) of a zone, BAC heating control system shall have multiple controls and intermittent scheduling adapted to zo

37、nes or spaces conditions of use. Special attention shall be done 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, A2: limit zones area

Yearly switch off heating over heating season. Switching off heating generation consist to switch off generators pumps, close tree ways valve

41、and/or partioning valves on the distribution. NOTE Fixed start-stop scheduler applied to outside temperature control (OTC), schedules these 3 modes: normal reduced - boost during 3 fixed programmed periods, for 3 expected temperature levels. Better energy efficiency of heating control system is prov

42、ided by optimum start-stop scheduler (OSS). Action of OSS consist to adapt automatically start time and duration of the boost period, in relation with outside temperature and/or room temperature.
