Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 8: Performance testing of un-ducted mechanical supply and exhaust ventilation units (including heat recovery) for mechanical ventilation systems intended for a single room

Scope

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].
