Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 8: Performance testing of non-ducted mechanical supply and exhaust ventilation units (including heat recovery)

This document specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal, acoustic and the electrical performance characteristics of non-ducted mechanical supply and exhaust residential ventilation units used in single dwellings.
The purpose of this document is not to consider the quality of ventilation but to test the performance of the equipment.
This document is applicable to ventilation units, the latter:
a) containing either:
- fans for mechanical supply and exhaust;
- air filters;
- air-to-air heat exchanger for heat and possibly humidity recovery;
- control system;
- inlet and outlet grilles; or
- alternating heat exchangers which provide separate supply and exhaust air flows;
b) provided either:
- in one assembly; or
- in more than one assembly, the separate assemblies of which are designed to be used together.
This document does not deal with ducted units which are covered by EN 13141-7 or units with heat pumps.
Safety requirements are given in EN 60335-2-40 and EN 60335-2-80.

Lüftung von Gebäuden - Leistungsprüfungen von Bauteilen/Produkten für die Lüftung von Wohnungen - Teil 8: Leistungsprüfung von mechanischen Zuluft- und Ablufteinheiten ohne Luftführung (einschließlich Wärmerückgewinnung)

Dieses Dokument legt die Laborprüfverfahren und die Prüfanforderungen an die Prüfung der aerodynamischen, thermischen, akustischen und der elektrischen Leistungskenngrößen von mechanischen Zuluft- und Abluftgeräten ohne Kanalanschluss für Wohnungen zur Verwendung in einzelnen Wohneinheiten fest.
Der Zweck dieses Dokuments besteht nicht in der Feststellung der Qualität der Lüftung, sondern in der Prüfung der Leistung der Ausrüstung.
Dieses Dokument ist auf Lüftungsgeräte anwendbar, die:
a)   enthalten entweder:
—   Ventilatoren für mechanische Zuluft- und Ablufteinheiten;
—   Luftfiltern;
—   Luft-Luft-Wärmeübertrager für die Wärme- und möglicherweise Feuchterückgewinnung;
—   Regel- und Steuereinrichtung;
—   Einström- und Ausströmluftgitter; oder
—   alternierende Wärmeübertrager mit getrennten Zuluft- und Fortluftströmen;
b)   geliefert werden:
—   in einer Baugruppe oder
—   in mehr als einer Baugruppe, wobei die einzelnen Bau¬gruppen dafür ausgelegt sind, zusammen verwendet zu werden.
Dieses Dokument behandelt keine Geräte mit Kanalanschluss welche in der EN 13141 7 behandelt werden oder Geräte mit Wärmepumpen.
Die Anforderungen an die Sicherheit sind in EN 60335 2 40 und EN 60335 2 80 angegeben.

Ventilation des bâtiments - Essais de performance des composants/produits pour la ventilation des logements - Partie 8 : Essais de performance des unités de ventilation double flux décentralisées (y compris la récupération de chaleur)

Le présent document spécifie les méthodes d’essai de laboratoire et les exigences d'essai pour les essais des caractéristiques de performances aérauliques, thermiques, acoustiques et électriques des unités de ventilation double flux décentralisées utilisées dans les logements individuels.
L’objet du présent document n’est pas d’estimer la qualité de la ventilation mais de soumettre à essai la performance de l'équipement.
Le présent document est applicable aux unités de ventilation, ces dernières :
a) comprenant soit :
- des ventilateurs pour l'insufflation et l'extraction mécaniques ;
- des filtres à air ;
- un échangeur de chaleur air-air pour la récupération de chaleur et éventuellement d'humidité ;
- un système de commande ;
- des grilles d'entrée et de sortie ; ou
- des échangeurs de chaleur alternatifs fournissant des flux d’air de soufflage et d’extraction séparés ;
b) fournies soit :
- en un assemblage ; ou
- en plus d’un assemblage, chacun de ces assemblages étant conçus pour être utilisés ensemble.
Le présent document ne traite pas des centrales qui sont couvertes par l’EN 13141-7 ou des unités avec pompes à chaleur.
Les exigences de sécurité sont données dans l’EN 60335-2-40 et l’EN 60335-2-80.

Prezračevanje stavb - Preskušanje lastnosti sestavnih delov/izdelkov za prezračevanje stanovanjskih stavb - 8. del: Preskušanje lastnosti mehanskih brezkanalnih dovodnih in odvodnih prezračevalnih enot (vključno z enotami za vračanje toplote)

Ta dokument določa laboratorijske preskusne metode in preskusne zahteve za preskušanje aerodinamičnih, toplotnih ter električnih lastnosti mehanskih brezkanalnih dovodnih in odvodnih prezračevalnih enot za posamezne prostore.
Ta dokument ni namenjen obravnavanju kakovosti prezračevanja, ampak preskušanju lastnosti opreme.
Prezračevalna enota na splošno zajema:
–   ventilatorje za mehanski dovod in odvod;
–   zračne filtre;
–   prenosnik toplote zrak-zrak za rekuperacijo toplote in po možnosti vlage;
–   nadzorni sistem;
–   vtočne in iztočne rešetke.
Taka oprema se lahko zagotovi v več sestavih, pri čemer so ločeni sestavi oblikovani tako, da se uporabljajo skupaj.
Taka oprema lahko zajema izmenične toplotne izmenjevalnike, ki zagotavljajo ločena pretoka dovodnega in odvodnega zraka.
V nekaterih primerih, tj. pri izmenični prezračevalni enoti, lahko proizvajalec izjavlja, da je mogoče opremo namestiti tako, da prezračuje več prostorov. Za namen tega dokumenta se ti izdelki ocenijo v enem samem prostoru.
Ta dokument ne obravnava kanalnih enot ali enot s toplotnimi črpalkami.
Varnostne zahteve so navedene v standardih EN 60335-2-40 in EN 60335-2-80.
