Pertains 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.

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. This European Standard covers both air free delivery and air ducted units with a maximum external static pressure due to duct resistance of 120Pa max. This European Standard applies to all types of fan speed control of a fan coil unit (variable speed, multispeed). This European Standard deals with the cooling and heating functions of the FCU considered as an emitter for cooling/heating of a room/space. It does not cover any ventilation function of the unit. If the FCU can also provide fresh air, this function is not considered and the fresh air inlet closed during testing. This European Standard provides a method for the determination of the thermal performance of fan coil units in standard conditions, for the use with hot or chilled water or water mixtures. The test procedures given in this standard may additionally be used for determining performance at other conditions. It also provides the method for the determination of the air flow rate supplied by the fan coil unit. This standard does not cover the rating of heating or cooling from direct expansion coils or heating from electric resistance elements. The standard does not cover acoustic performance of fan coil units which is dealt with in EN16583 . 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.
