The standar

18、d 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 i

19、s 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 EN 1397:2015. 2 Normative references The following documents, in whole or in part, are normati

The control of the relative humidity is not required. If the unit includes flaps, they shall be adjusted in a fixed position ac

35、cording 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 bu

36、t 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 stand
