EN 1264系列给出了安装在建筑物、住宅和非住宅(如办公、公共、商业和工业建筑)中的表面嵌入式加热和冷却系统的指南,并侧重于为热舒适目的安装的系统。
EN 1264系列给出了嵌入待加热或待冷却房间外壳表面的水基加热和冷却系统的指南。它还规定了使用其他加热介质代替水,视情况而定。
EN 1264系列通过计算和测试技术规范和认证的加热热输出,规定了标准化的产品特性。关于这些系统的设计、构造和操作,见EN 1264-3和EN 1264-4中A、B、C、D、H、I和J型。对于E、F和G型,见EN ISO 11855系列。
EN 1264系列中规定的系统与建筑物外壳表面的结构基座相连,直接安装或用固定支架安装。EN 1264系列没有规定安装在吊顶内的吊顶系统,该吊顶系统和建筑结构之间设计有开放的空气间隙,允许热诱导空气循环。这些系统的热输出可根据EN 14037系列和EN 14240确定。
EN 1264-2规定了热水地板供暖系统。EN 1264-5的应用要求事先使用EN 1264-2。EN 1264-5规定了将EN 1264-2中确定的地板供暖系统的热输出转换为嵌入墙壁和天花板的受热面热输出以及嵌入地板、墙壁和天花板的冷却面热输出的转换。
EN 1264-2规定了边界条件和试验方法,用于确定热水地板供暖系统的热输出,作为加热介质和室温之间温差的函数。
用计算法和测量法对热输出进行了测试。该计算方法适用于符合EN 1264-1(A、B、C、D、H、I和J型)定义的系统。测量方法为不符合这些定义的系统提供了指导。计算方法与测量方法一致,提供了相关的、充分的试验结果。
试验结果取决于其他参数,是标准比热输出和加热介质与室温之间的相关标准温差,以及显示比热输出和加热介质与室温之间的温差之间关系的特性曲线场。
The EN 1264 series gives guidelines for surface embedded heating and cooling systems installed in buildings, residential and non-residential (e.g. office, public, commercial and industrial buildings) and focuses on systems installed for the purpose of thermal comfort.
The EN 1264 series gives guidelines for water based heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. It also specifies the use of other heating media instead of water, as appropriate.
The EN 1264 series specifies standardized product characteristics by calculation and testing the thermal output of heating for technical specifications and certification. For the design, construction and operation of these systems, see EN 1264-3 and EN 1264-4 for the types A, B, C, D, H, I and J. For the types E, F and G, see the EN ISO 11855 series.
The systems specified in the EN 1264 series are adjoined to the structural base of the enclosure surfaces of the building, mounted directly or with fixing supports. The EN 1264 series does not specify ceiling systems mounted in a suspended ceiling with a designed open air gap between the system and the building structure which allows the thermally induced circulation of the air. The thermal output of these systems can be determined according to the EN 14037 series and EN 14240.
EN 1264-2 specifies hot water floor heating systems. The application of EN 1264-5 requires the prior use of EN 1264-2. EN 1264-5 specifies the conversion of the thermal output of floor heating systems determined in EN 1264-2 into the thermal output of heating surfaces embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings.
EN 1264-2 specifies the boundary conditions and the test methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the room temperature.
The thermal output is tested by a calculation method and by a measurement method. The calculation method is applicable to systems corresponding to the definitions in EN 1264-1 (type A, B, C, D, H, I and J). The measurement method gives guidance for systems not corresponding to these definitions. The calculation method and the measurement method are consistent with each other and provide correlating and adequate test results.
The test results, expressed depending on further parameters, are the standard specific thermal output and the associated standard temperature difference between the heating medium and the room temperature as well as fields of characteristic curves showing the relationship between the specific thermal output and the temperature difference between the heating medium and the room.
