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.

EN 16583:2015 (E) 5 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 hydronic fan-coil unit factory-made single assembly which provides one or more of the functions of forced circulation of air, heating, cooling, dehumidification and filtering of air, but which does not include the source of heating or cooling Note 1

to entry: This device includes at least a liquid-to-air heat exchanger and a fan, and may be designed for free or ducted intake air and/or for free or ducted delivery of supply air. 3.2 total electric power input total electric power absorbed by the unit, including fan(s) and auxiliary devices but excluding any electrical resistance heater 3.3 standard fan speed fan speed setting declared by the manufacturer and used for setting the air flow rate conditions of ducted units Note 1 to entry: The fan speed setting can be declared by the manufacturer as a certain wiring, a switch position or a steering voltage. 3.4 external static pressure positive pressure difference measured between the air outlet and inlet sections of the unit 3.5 acoustics for acoustic quantities, the definitions of EN ISO 80000-8:2007 apply 4 Measuring instruments The acoustic instruments shall fulfil the requirements of the acoustic standard used for the test. 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, preliminary tests shall be done to determine the external static difference for each additional speed. SIST EN 16583:2015
