Scope of the programme

All Fan Coil Units (Ducted and Non Ducted) defined by ECC Rating Standards 6/C/002 and 6/C/002A are included in this programme.

Companies may apply to participate in the following certification Sub-programmes:

- Non ducted units: Fan Coil Units with air flow lower than 0.7m3/s and a published external static duct pressure at 40 Pa maximum

- Ducted units: Fan Coil Units up to 1m3/s airflow and 300 Pa available pressure

“Certify-all” requirement: If a Company participates in the certification programme, all production models, within the scope of the programme for ducted and non-ducted units, shall be certified in accordance with the relevant Rating Standard.

Variable speed Fan Coil units are included in this programme.
Units running at 60 Hz and District cooling units can be declared but they are excluded from the "Certify-All" requirement.

Participants shall provide ECC their selection tool(s). ECC shall check the selection tool(s) every year.


Definitions

A Fan Coil unit is a factory made assembly which provides the functions of cooling and/or heating air using chilled or hot water with air flow to the room ensured by one or more electrically driven fans. Fan Coil Units may be of the cabinet style, within a room, for free air delivery, or of the chassis style, concealed within the building structure with minimal ducting appropriately connected to the inlet and/or outlet of the unit.

The principal components are:

    one or more heat exchangers,
    one or more fans with electric motors,
    an appropriate enclosure,
    condensed water collecting facilities when cooling,
    air filter

Total Cooling Capacity [kW]: Total heat energy removed from the air by the unit which is the sum of the sensible and latent cooling capacities. The total cooling capacity is determined as the cooling capacity measured on the water side minus the fan power input (net value) (new definition from 2016 campaign).

Sensible Cooling Capacity [kW]: Heat which is removed from the air by means of a dry-bulb temperature drop.

Latent Cooling Capacity [kW]: Heat which is removed from the air by condensation of water vapour on the cooling coil.

Heating Capacity [kW]: Total heat added to the air by the unit. The heating capacity is determined as the heating capacity measured on the water side plus the fan power input.

Fan Power Input [W]: Electric power absorbed by the fan(s) of the unit.

Water Pressure Drop [kPa]: Negative pressure difference measured between the outlet and inlet connections of the water circuit of the unit.

Sound Power [dB]: Total sound power radiated by the Fan Coil Unit.

A-weighted Sound Power [dB(A)]: A single figure on a specific scale which can be related to the subjective assessment of the loudness of a noise.

Air flow rate [m3/h]: Volume air flow through the unit at standard conditions.

RPM: Motor rotational speed for dry coils.
Testing requirements

For ducted and non-ducted units:

Standard Ratings shall be verified by tests conducted by the ECC-selected laboratory in accordance with the following standards:

Thermal Performance testing:

The thermal test has to be performed according to EN 1397:2015 “Heat exchangers - Hydronic room fan coil units – Test procedures for establishing the performance” at the speed chosen by Eurovent Certita Certification (Low, Medium or High speed).

Air flow testing:

The air flow rate test has to be performed according to EN 1397:2015 “Heat exchangers - Hydronic room fan coil units – Test procedures for establishing the performance” for the 3 declared speeds (Low, Medium and High speed).

Acoustical testing:

The sound power test has to be performed according to EN 16583:2015 “Heat exchangers - Hydronic room fan coils units – Determination of the sound power level” for the 3 declared speeds (Low, Medium and High speed).

Details for ducted units:

The thermal test has to be performed

§   with discharge plenum

§   with standard filter

§   with static pressure of 50 Pa at medium speed. If the low or the high speed is chosen for the test the same setting of installation shall be set. (The speed of choice has to be hard-wired to the fan)

For the sound tests ducted units will be installed between two reverberation rooms. Two sound powers will be measured: discharge and inlet + radiated. Testing will be performed for all three speeds used for air flow rate measurements.

Air flow rate test shall be carried out at ambient conditions without water flow. Measured values shall be transposed to the standard conditions.

All tests shall be carried out with the air filter fitted as supplied by the manufacturer.
Certified characteristics

Thermal characteristics:

ECC shall select one speed (low, medium or high) for the thermal test and one application rating condition.

The following performance characteristics declared by the manufacturer at the selected speed shall be verified by tests at standard rating conditions:

  • Total cooling capacity
  • Sensible cooling capacity
  • Heating capacity
  • Water pressure drops in cooling and heating
  • Fan power input in cooling and heating

In addition the following non-standard performance characteristics declared by the manufacturer at the selected speed shall be verified by tests at the selected application rating condition (cooling or heating):

  • Total cooling capacity
  • Sensible cooling capacity
  • Water pressure drops in cooling
  • Fan power input in cooling

Or

  • Heating capacity
  • Water pressure drops in heating
  • Fan power input in heating

Note: Only standard performance characteristics are published on ECC website.

Acoustical characteristics:

The following performance characteristics at low, medium and high speeds (three tested speeds) shall be verified by tests:

  • A-weighted sound power for non-ducted units
  • A-weighted sound power for (inlet + envelope) and outlet duct for ducted units

Aeraulic characteristics:

  • Air flow rate (mandatory for ducted units, optional for non-ducted units)
  • Available static pressure (only for ducted units)

The declaration of air flow rate is optional for non-ducted units but, if applied, the air flow rate shall be verified at the fan speeds used for the testing of A-weighted sound power.

Energy efficiency classification

The Fan Coil Energy Efficiency Ratio (FCEER) and the Fan Coil Coefficient of Performance (FCCOP) allows to assess the energy efficiency of each units in cooling and heating mode.

For each unit the participant shall select three speeds called high, medium and low speed. FCEER and FCCOP are defined as follows:

Temporary definition of FCEER and FCCOP for 2017 campaign:

FCEER = (65%*(PcLow+PecLow)+30%*(PcMed+PecMed)+5%*(PcHigh+PecHigh))/(65%*PecLow+30%*PecMed+5%*PecHigh)

FCCOP = (70%*PhNS1Low+25%*PhNS1Med+5%*PhNS1High)/(70%*PehNS1Low+25%*PehNS1Med+5%*PehNS1High)

Definition of FCEER from 2018 campaign:

FCEER = (65%*PcLow+30%*PcMed+5%*PcHigh)/(65%*PecLow+30%*PecMed+5%*PecHigh)

FCCOP = (70%*PhLow+25%*PhMed+5%*PhHigh)/(70%*PehLow+25%*PehMed+5%*PehHigh)
