European foreword
This document (EN 16583:2022) has been prepared by Technical Committee CEN/TC 113 “Heat pumps
and air conditioning units”, the secretariat of which is held by UNE.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2023, and conflicting national standards shall
be withdrawn at the latest by January 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 16583:2015.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.
This document was prepared in the framework of the Commission Regulation (EU) 2016/2281 of 30
November 2016 implementing Directive 2009/125/EC of the European Parliament and of the Council
establishing a framework for the setting of ecodesign requirements for energy-related products, with
regard to ecodesign requirements for air heating products, cooling products, high temperature process
chillers and fan coil units.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
1 Scope
This document is applicable 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 document is applicable to both air free delivery and air ducted units with a maximum external static
pressure due to duct resistance of 300 Pa max.
This document specifies 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 document 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”.
