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 power of a mechanical supply and exhaust ventilation unit used
in a single dwelling.
In general such a unit contains:
- supply and exhaust air fans;
- air filters;
- air to air heat exchanger with/without air to air heat pump for exhaust air heat recovery;
- control system.
Such equipment can be provided in more than one assembly, the separate assemblies of which are designed to be used together.
This standard does not deal with non-ducted units.
The method of testing for the performances of the heat pumps for heat recovery is generally given in EN 255-2 and in ENV 12102. Safety requirements are given in EN 60335-2-40 and EN 60335-2-80.
