For some of the measures laid down in this standard, stricter statutory provisions have been laid down in German laws such as the Energieeinsparverordnung (EnEV) (German Energy Saving Ordinance). These measures deal with central control (4.5.3), local control (4.5.5), timing control (4.5.6)

7、and thermal insulation (4.8). Although this European Standard also covers indirectly heated systems, in some European member countries additional requirements have been laid down by regional or supra-regional power utilities or organizations that must be met by substations and domestic systems direc

In Germany DIN 4747-1 and AGFW-Arbeitsblatt FW 527 apply to hot-water district heating networks and AGFW-Arbeitsblatt FW 519 applies to steam-based systems.

32、an Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2014, and conflicting national standards shall be withdrawn at the latest by October 2014. Attention is drawn to the possibility that some of the eleme

The main changes !between EN 12828:2003 and EN 12828:2012 were“: restrictions concerning additional safety requirements for systems larger than 1 MW were removed; an informative annex for safety valves was added; definitions were co

35、rrected and added; the guidance for dimensioning of diaphragm expansion vessels (sealed systems) in Annex D was revised, and a figure describing the different pressure level was added; a specification for the water used has been added in 4.3.2.1; the requirements concerning safety arrangements (4.6)

36、 were revised and clarified; 4.7.4 concerning pressure maintaining control device was revised.

38、ingdom. DIN EN 12828:2014-07EN 12828:2012+A1:2014 (E) 5 Introduction The subjects covered by CEN/TC 228 are the following: design of heating systems (water based, electrical, etc.); installation of heating systems; commissioning of heating systems; instructions for operation, maintenance and use of

39、heating systems; methods for calculation of the design heat loss and heat load; methods for calculation of the energy performance of heating systems. Heating systems also include the effect of attached systems such as hot water production systems. All these standards are system standards, i.e. they

40、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 CEN or ISO standards, e.g. product standards. However, use of products complying with relevant product standards is no guarante

41、e of compliance with the system requirements. The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system and not specifying shape, material, dimensions or the like. The guidelines describe ways to meet the requirements, but other ways

42、to fulfil the functional requirements may be used if fulfilment can be proved. Heating systems differ among the member countries due to climate, traditions and national regulations. In some cases, requirements are given as classes so national or individual needs may be accommodated. In cases where t

43、he standards contradict with national regulations, the latter should be followed. DIN EN 12828:2014-07EN 12828:2012+A1:2014 (E) 6 1 Scope This European Standard specifies design criteria for water based heating systems in buildings with a maximum operating temperature of up to 105 C. In case of heat

44、ing systems with maximum operating temperatures over 105 C other safety aspects than those described in 4.6 may apply. The other clauses of this European Standard are still valid for those systems. This European Standard does not amend product standards or product installation requirements. This sta

45、ndard covers the design of: heat supply systems; heat distribution systems; heat emission systems; control systems. This European Standard takes into account heating requirements of attached systems (e.g. domestic hot water, process heat, air conditioning, ventilation) in the design of a heat supply

46、, but does not cover the design of these systems. This European Standard does not cover requirements for installation or commissioning or instructions for operation, maintenance and use of water based heating systems. This European Standard does not cover the design of fuel and energy supply systems
