本欧洲标准规定了空气动力学，热和声学性能的测试实验室测试方法和测试要求，以及单个房间中使用的未管道机械供排气通风单元的电力。 本欧洲标准的目的不是考虑通风的质量，而是测试设备的性能。 通常，通风单元包含: - 排气风机; - 空气过滤器 - 空气对空气热交换器或空气储存物质，用于排放空气的热和湿度回收; - 控制系统; - 入口和出口格栅。 这种设备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。 这种设备可以包含交替的热交换器，其提供单独的供应和排出空气流。 在某些情况下，即交替通风单元，制造商可以建议设备可以以多于一个房间的方式安装。为了本欧洲标准的目的，这些产品在单个房间进行评估。 本欧洲标准不涉及带有热泵的管道单元或单元。 EN 60335 2 80:2003 [2]中给出了安全要求

This European Standard specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal and acoustic performance, and the electrical power of an un-ducted mechanical supply and exhaust ventilation unit used in a single room. The purpose of this European Standard is not to consider the quality of ventilation but to test the performance of the equipment. In general, a ventilation unit contains: - supply and exhaust air fans; - air filters; - air to air heat exchanger or air storage mass for exhaust air heat and humidity recovery; - control system; - inlet and outlet grilles. Such equipment can be provided in more than one assembly, the separate assemblies of which are designed to be used together. Such equipment can contain alternating heat exchangers which provide separate supply and exhaust air flows. In certain cases, i.e. alternating ventilation unit, the manufacturer may recommend that the equipment can be installed in such a way that it serves more than one room. For the purpose of this European Standard, these products are assessed in a single room. This European Standard does not deal with ducted units or units with heat pumps. Safety requirements are given in EN 60335 2 80:2003 [2].
