This document specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal, acoustic and electrical performance characteristics of ducted mechanical supply and exhaust residential ventilation units.<\/p>\n

\n
\n NOTE\n <\/div>\n

Such units are referred to as bidirectional ventilation units in EN 13142:2021<\/span><\/span> .<\/p>\n<\/div>\n

This document is applicable to unit that contain at least, within one or more casing:<\/p>\n

    \n
  1. \n

    fans for mechanical supply and exhaust;<\/p>\n<\/li>\n

  2. \n

    air filters;<\/p>\n<\/li>\n

  3. \n

    air-to-air heat exchanger and\/or air-to-air heat pump for air heat recovery;<\/p>\n<\/li>\n

  4. \n

    control system.<\/p>\n<\/li>\n<\/ol>\n

    Such unit can be provided in more than one assembly, the separate assemblies of which are designed to be used together.<\/p>\n

    Examples of different possible arrangements of heat recovery, heat exchangers and\/or heat pumps are described in Annex A<\/span>.<\/p>\n

    This document covers ventilation units with continuous mass flows for each setting point.<\/p>\n

    This document does not deal with non-ducted units that are treated in prEN 13141?8:2021<\/span><\/span>.<\/p>\n

    This document does not cover ventilation systems that may also provide water space heating and hot water that are treated in EN 16573<\/span><\/span>.<\/p>\n

    This document does not cover units including combustion engine driven compression heat pumps and absorption heat pumps.<\/p>\n

    Electrical safety requirements are given in EN 60335?2?40<\/span><\/span> and EN 60335?2?80<\/span><\/span>.<\/p>\n
