DIN EN 16583:2015-10 EN 16583:2015 (E) 4 1 Scope This European Standard applies to hydronic fan coil un
19、its (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 Eu
20、ropean 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, t
21、he term “unit” is used to mean “fan coil unit” as defined in 3.1 of EN 1397:2015. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

29、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
30、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
31、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 sectio

Other measurements can be necessary for the tests: Electrical: voltage (V), cu
33、rrent (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. DIN EN 16583:2015-10 EN 16583:2015

36、nlet air temperatures between 15 C and 25 C. The control of the relative humidity is not required. 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 m
37、echanical 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 modificat

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 Fig
39、ure 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.
