30、hy 53Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-5 Introduction The subjects covered by CEN/TC 228 are the following: design of heating systems (water based, electrical, etc.

31、); installation of heating systems; commissioning of heating systems; instructions for operation, maintenance and use of 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

32、the effect of attached systems such as hot water production systems. All these standards are system standards, i.e. they 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

33、 ISO standards, e.g. product standards. However, use of products complying with relevant product standards is no guarantee 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 s

34、pecifying shape, material, dimensions or the like. The guidelines describe ways to meet the requirements, but other ways 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 regulation

35、s. In some cases, requirements are given as classes so national or individual needs may be accommodated. In cases where the standards contradict with national regulations, the latter should be followed. BS EN 12828:2012 EN 12828:2012 (E)Copyright European Committee for Standardization Provided by IH

36、S under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-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 heating systems with maxi

37、mum 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 standard covers the desi

38、gn 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, but does not cover

39、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. 2 Normative referen
