EN 13141的这一部分规定了单一住宅中使用的机械供排气通风单元的空气动力学，热和声学性能以及电气性能特性的实验室测试方法和测试要求。 它涵盖至少包含一个或多个外壳内的单元: - 排气风机; - 空气过滤器 - 空对空换热器和/或提取空气到户外空气热泵，用于提取空气热回收; - 控制系统。 这种单元可以设置在多于一个组件中，其单独的组件被设计为一起使用。 热回收热交换器和/或热泵的不同可能的布置在附件A中描述。 本标准不涉及非管道单元或往复式热交换器。 本标准不涉及提供多个住宅的单位。 本标准不包括也可以提供水空间加热和热水的通风系统。 本标准不包括内燃机驱动的压缩热泵和吸收式热泵的单元。 EN 60335-2-40和EN 60335-2-80给出了电气安全要求

This part of EN 13141 specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal and acoustic performance, and the electrical performance characteristic of a mechanical supply and exhaust ventilation units used in a single dwelling. It covers unit that contain at least, within one or more casing: - supply and exhaust air fans; - air filters; - air-to-air heat exchanger and/or Extract Air-to-Outdoor Air heat pump for extract air heat recovery; - control system. Such unit can be provided in more than one assembly, the separate assemblies of which are designed to be used together. The different possible arrangements of heat recovery heat exchangers and/or heat pumps are described in Annex A. This standard does not deal with non-ducted units or reciprocating heat exchangers. This standard does not deal with units that supply several dwellings. This standard does not cover ventilation systems that may also provide water space heating and hot water. This standard does not cover units including combustion engine driven compression heat pumps and absorption heat pumps. Electrical safety requirements are given in EN 60335-2-40 and EN 60335-2-80.
