36、ystem consists on integrated functions applied to all parts of the water heating system: emission or room control by TRV or RTC, flow temperature control by OTC control, FSS, OSS, pumps and generators sequencing and controls, thermal storage management, cost optimization of thermal resources taking
37、account smart metering, predictable or detected occupancy. 5.2 Partitioning control heating zones in buildings 5.2.1 General For efficiently control heating, the flow temperature level of generation and distribution system shall satisfy heat demand to the lowest flow temperature. For this purpose, f
38、low temperature 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; Partitioning of heati
39、ng systems described on EN 5200-1:2016, Clause 10, 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 cont
40、rols and intermittent scheduling adapted to zones 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 indicatio
41、n is given in EN 1531623:2007, A2: limit zones area to 1000 m2 (one pump for a maximum of 1 000 m2). 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
42、 and OSS and complementary integrated functions specified by prEN 12098-1:2016 and fulfil items in prEN 15232-1:2015, Table 1, 1.3, 1.4, 1.4, 1.5. NOTE Better control and scheduling of heating systems imply a data communication network linking control devices for integration of these functions and o
43、ther technical building management capabilities for energy performance. For these parts, objectives of control functions are: the lowest flow temperature and the longest reduced or stop heat generation periods and pumps operation. PD CEN/TR 12098-6:2016 CEN/TR 12098-6:2016 (E) 9 Generation (see prEN
44、 15316-4-1:2016) and distribution (see EN 153162-3) parts are controlled acting water flow temperature while emission is controlled via the flow through emitters. These central controls applied to building, zones and spaces (see Figure 1) taking into account thermal characteristics and conditions of
45、 use (see prEN ISO 52000-1:2016, Clause 10, D.2, D.3). Emitters of a zone or space controlled by an OTC controller shall be of the same model, for conformity with a single heating curve shape common to all emitters of the controlled zone, i.e. dont mix different types of steel radiators, heating flo
46、or or fan coil on a distribution controlled by an OTC controller. 5.2.2 Emission control Individual control of emitters or RTC completes central control by individual emitters controllers acting flow through emitters. The aim of individual control consist to adapt conditions of operation (individual
47、 set point, individual scheduling), to consumers needs (see prEN 15232-1:2016, Figure 1) and to compensate room heat gains, reducing heating for comfort and energy saving. However, individual room temperature control performance doesnt depend only of individual controllers; it depends also of the fl
48、ow temperature central (generation, distribution) control, mainly for these cases: Emitters are not equipped with efficient electronic individual RTC (conform to prEN 15500-1:2016); Users are not encouraged to adapt the set point of their room temperature controller considering their comfort needs r
49、elated to energy consumption; Heated room or space dont permit to measure a representative temperature for individual (closed loop) RTC, e.g.: entrance, corridor, reception hall, exhibition hall, atrium, Emission control is operated only by the flow temperature control (generation, distribution parts). Whatever: For accuracy of a room controller, the flow temperature of emitters shall be adapted to the heating load; i.e. related to the main influence, the outside
