This European Standard establishes requirements for determining, in accordance with a standardized procedure, the sound power level emitted into the surrounding air by air conditioners, heat pumps, liquid chilling packages with electrically driven compressors when used for space heating and/or cooling, including water cooled multisplit systems, as described in EN 14511 and dehumidifiers as described in EN 810.
This European Standard also covers the measurement of the sound power level of evaporatively-cooled condenser air conditioners, as defined in EN 15218. However, the measurement should be done without external water feeding and these units will thus be considered as the other air conditioners covered by EN 14511.
It is emphasised that this measurement standard only refers to airborne noise.
This European Standard offers ways to determine the sound power level of units. Some of them are specifically adapted to provide results with low uncertainties, by using laboratory class acoustic methods and highly controlled working conditions. Those measurements are suitable for certification, labelling and marking purposes.
In some cases, the target and/or the environment of the measurements do not allow such precision-class methods. This European Standard also offers ways to assess sound power levels with acceptable accuracy even though acoustic methods and/or working conditions are not laboratory-type, e.g. in situ or quality control measurements.
This European Standard gives two classes of measurements and results, according to the test environment:
-   Class A measurements correspond to controlled working conditions (standard or application rating conditions). It is defined by the respect to the tolerances of Table 2 and should be used for the conformity to requirements of the Commission Regulation (EC) No 206/2012 of 6 March 2012 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for air conditioners
-   Class B measurements correspond to the case where the range defined by the tolerances of Table 2 cannot be fulfilled.
In both classes, precision or engineering class acoustic methods should be applied. The choice of the acoustic measurement method is done in accordance with EN ISO 3740 and EN ISO 9614 depending on the type of surrounding acoustic fields (diffuse or free field, enclosed or open space), and the available instrumentation. Whatever the current working conditions, the reference of acoustic standard should be reported, with explicit mention of its accuracy class.
The use of EN ISO 3746 and EN ISO 3747 as survey grade methods are not recommended due to the high level of uncertainties. Their use is only allowed for non controlled environments.
Three methods for determining the sound power levels are specified in order to avoid unduly restricting existing facilities and experience:
-   the first methodology is based on reverberation room measurement (see EN ISO 3741, EN ISO 3743 and EN ISO 3747 in some favourable cases when the engineering grade can be fulfilled);
-   the second method is based on measurements in an essentially free field over a reflecting plane (see EN ISO 3744 and EN ISO 3745);
-   the third method is based on sound intensity measurement (see EN ISO 9614) in preferably free field environment.
The references in this European Standard to EN ISO 3743 should be understood as EN ISO 3743-1 or EN ISO 3743-2 as well.
The necessity to regulate the test conditions obviously leads to recommend test methods implemented in acoustically designed (enclosed) spaces, such as EN ISO 3741, EN ISO 3743, EN ISO 3745 and also EN ISO 9614 when implemented in an enclosed space.
The open spaces should be covered only in specific cases, e.g. when the size or the power of the unit under test cannot be managed by standard test rooms. Suitable test methods are EN ISO 3744 and EN ISO 9614.

This European Standard specifies methods for testing and reporting of the rating and it specifies requirements for marking of air/water, brine/water, water/water and direct exchange/water heat pumps with electrically driven compressors connected to or including a domestic hot water storage tank. When these units are used for space heating, then EN 14511 (all parts) applies.
In case of air-to-water heat pumps, this European Standard comprises only factory-made units which can be ducted on the airside.
This European Standard comprises only the testing procedure for the domestic hot water production of the heat pump system.
NOTE   Testing procedures for simultaneous operation for domestic hot water production and space heating are not treated in this standard. Simultaneous means that domestic hot water production and space heating generation occur at the same time and may interact.
In the case of units consisting of several parts, the standard applies only to those designed and supplied as a complete package.
This European Standard does not include any requirement about the quality of water.

This European Standard specifies the rating conditions, tolerances and presentation of manufacturer's performance data for condensing units for refrigeration with compressors of the positive-displacement type. These include single stage compressors and single and two stage compressors having an integrated means of fluid sub cooling. This is required so that a comparison of different condensing units can be made. The data relate to the refrigerating capacity and power absorbed and include requirements for part-load performance where applicable.

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.
