Heat exchangers - Hydronic room fan coils units - Determination of the sound power level
This European Standard applies to hydronic fan coil units (FCU) as factory-made single assemblies which provide the functions of cooling and/or heating but do not include the source of cooling or heating.
The standard covers both air free delivery and air ducted units with a maximum external static pressure due to duct resistance of 120 Pa max.
This European Standard provides methods for the determination of the acoustical performance of fan coil units, defining standard working condition and installation.
It is not the purpose of this standard to specify the tests used for production or field testing.
NOTE For the purpose of remaining clauses, the term “unit” is used to mean “fan coil unit” as defined in 3.1 of FprEN 1397:2015.
Wärmeübertrager - Wasser-Luft-Ventilatorkonvektoren - Bestimmung des Schallleistungspegels
Diese Europäische Norm gilt für fabrikmäßig gefertigte einzelne Baueinheiten von Wasser-Luft-Ventilator-konvektoren (Ventilatorkonvektor, FCU, en: fan coil unit), die eine Kühl- und/oder Heizfunktion bieten, jedoch keine eigene Kühl- oder Heizquelle enthalten.
Die vorliegende Norm deckt sowohl Geräte mit ungehinderter Luftabgabe als auch solche mit Luftkanalanschluss ab, die aufgrund des Kanalwiderstands einen maximalen statischen Außendruck von höchstens 120 Pa aufweisen.
Diese Europäische Norm enthält Verfahren für die Bestimmung des akustischen Verhaltens von Ventilator-konvektoren und definiert Norm-Betriebsbedingungen sowie den Einbau.
Die Festlegung von Produktions- oder Einsatzprüfungen ist nicht Zweck dieser Norm.
ANMERKUNG In den folgenden Abschnitten steht die Benennung „Gerät“ für „Ventilatorkonvektor“ entsprechend der Definition nach FprEN 1397:2015, 3.1.
Échangeurs thermiques - Ventilo-convecteurs à eau - Détermination du niveau de puissance acoustique
La présente Norme européenne s'applique aux ventilo-convecteurs à eau en tant qu'ensembles autonomes fabriqués en usine, assurant des fonctions de refroidissement et/ou de chauffage, mais n'intégrant pas la source de refroidissement ou de chauffage.
Cette norme concerne les unités à soufflage libre et les unités raccordées sur l’air conçues pour une pression statique externe due à la résistance de circuit de 120 Pa maximum.
La présente Norme européenne fournit des méthodes de détermination des performances acoustiques des ventilo-convecteurs, la définition des conditions de fonctionnement standards et d'installation.
Cette norme européenne n'a pas pour objet de spécifier les types d'essais utilisés en production ou sur site.
NOTE Pour les besoins des articles ci-après, le terme « unité » est utilisé pour désigner un « ventilo-convecteur » tel que défini en 3.1 de l’EN 1397:2015.

Ta evropski standard velja za ventilatorske konvektorje voda/zrak (FCU) kot tovarniško izdelane enojne sestave, ki zagotavljajo funkciji ohlajanja in/ali ogrevanja, vendar ne vključujejo vira ohlajanja ali ogrevanja.
Ta standard zajema enote za prosto dovajanje zraka in enote s prezračevalnimi cevmi z maksimalnim zunanjim statičnim tlakom zaradi maksimalne tlačne odpornosti 120 Pa.
Ta evropski standard opisuje metode za določanje akustičnih lastnosti konvektorjev ter določa standardne delovne pogoje in namestitev.
Cilj tega standarda ni določanje preskusov za proizvodnjo ali preskušanje na terenu.
OPOMBA: V naslednjih točkah izraz »enota« pomeni »ventilatorski konvektor«, kot je določeno v točki 3.1 standarda FprEN 1397:2015.

Other measurements can be necessary for the tests: — Electrical: voltage (V), current (A), total electric power input (W); — Pressure (Pa); — Rotation speed (min-1). Measurements for the ambient conditions: — Relative humidity (%); — Air Temperature (°C); — Atmospheric pressure (kPa). Table 1 gives the uncertainties allowed for these measurement values.

If the unit includes flaps, they shall be adjusted in a fixed position according to the manufacturer instructions. If this information is not available, their position shall correspond to the maximum mechanical open position. NOTE 1 This maximum mechanical open position might differ from the minimum airflow resistance. For testing, the unit shall include an air filter but no any other accessory for air inlet or diffusion or others. Dampers for fresh air intake shall be closed. NOTE 2 No modification such as sealing is made on the unit before testing. For ducted units, an external static pressure difference of 50 Pa (± 1 Pa) shall be applied to the unit for the standard fan speed declared by the manufacturer. If other speeds are tested, the same network curve resistance shall be used. See Figure 1. If the resistance is obtained by using an auxiliary fan, prel
