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.
The standard applies to all types of fan speed control of a fan coil unit (variable speed, multispeed).
This 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.
The 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 EN 16583.
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.

This document specifies methods to be used for testing of air-to-air heat recovery components (HRC). The main purpose of the HRC is to exchange heat between exhaust air and supply air in order to save energy, which results in
— preheat or heat, and/or
— precool or cool
supply air in ventilation systems or air conditioning systems. Optionally HRC can exchange air humidity between exhaust and supply air. The HRC contains the heat exchangers and all necessary features and auxiliary devices for the exchange of sensible heat and (if available) air humidity between exhaust air and supply air. The HRC will be installed in casings or ducts. If fans are part of the test unit, the effect of the fan power on the measured values will be corrected.
This document specifies procedures and input criteria required for tests to determine the performance of a HRC at one or several test conditions, each of them with continuous and stationary air flows, air temperatures and humidities at both inlet sides. Three different test types are covered:
— Test type A, Laboratory testing of HRC installed in test casings (A1) or a HRC sections (A2);
— Test type B, Laboratory testing of HRC installed in non-residential ventilation units in design configuration;
— Test type C, on-site (field) testing of HRC in non-residential ventilation units (C1) or a HRC sections (C2) in operation configuration.
This document is applicable to recuperators, regenerators, and HRC with intermediary heat transfer medium.
This document prescribes test methods for determining:
1) the temperature and humidity efficiency,
2) the pressure drop of exhaust air and supply air sides,
3) possible internal leakages; exhaust air transfer ratio (EATR) and outdoor air correction factor (OACF),
4) external leakages and
5) auxiliary energy used for the operation of the HRC.
HRC using heat pumps are not covered by this document.
