Scope of the programme

This Certification Programme applies to air-to-air rooftops and water-to-air rooftops as defined in section III.1 of RS 6/C/007-2018 for Rooftops, rated up to 200 kW in cooling capacity as defined in EN 14511:2013.

Declaring rooftops with 3 or 4 dampers, as described in the section III.1 of RS 6/C/007-2018, is optional.

The following features are not certified:
  • gaz burners,
  • pre-heaters,
  • heaters,
  • additionnal internal coil,
  • heat recovery (plate, wheels, thermodynamic systems),
  • exhaust fans.
  • split rooftop
  • roomtop
The programme is splitted into three sub-programmes:
  • One mandatory sub-programme: Air-to-air units Up to 100 kW
  • Two optional sub-programmes:
                  - Air-to-air units from 100 kW to 200 kW
                  - Water-to-air units up to 200 kW

Minimum and maximum external static pressure requirements are defined in standard EN 14511-3:2013.


A rooftop unit is defined by the following features:
  • Air-to-air rooftop: Units covered by ErP regulation No 2016/2281 will entry into force on 01/01/2018 and defined as a: Rooftop air conditioner or Rooftop heat pump
  • Water-to-air rooftop: Water-to-air heat pump/air conditioner (defined and covered by the regulation), driven by an electric compressor, of which the evaporateur, compressor and condenser are integrated into a single package.

Features according definitions from ErP regulation:
  • Single packaged unit assembled in factory
  • Common single frame
  • Direct expansion system
  • For Air-to-air unit, the outdoor side heat exchanger (condenser / evaporator) allows heat transfer with 100% outdoor (ambient) air.

Additional features:
  • Designed to operate permanently outdoor
  • The rooftop is designed to permanently handle 100% recycled air with the possibility of mixing partly the fresh air.
  • The outdoor fan from an air-to-air rooftop could be ducted but for the certification tests, the unit must be not ducted.
  • Rooftops could be equiped with 2 / 3 or 4 dampers depending on heat recovery system included or not.

These types of rooftops shall be tested :
  • For the indoor heat exchanger with mixed air equal to 100% extract air and,
  • For the ‘ outdoor ‘ heat exchanger with 100% outdoor air.
  • Other parameters in accordance with the standards EN 14511:2013 and EN 14825:2016.

Basic models groups (BMG)

A Basic Model Groups (BMG) is a list of Rooftops models, part of a common commercial range sharing the same overall dimensions:
  • Height (mm)
  • Width (mm)
  • Length (mm)
with the same function and application (For instance, reversible rooftops and cooling only rooftops are in two separate Basic Model Groups).
with similar components (fans, coils, compressors and motors).

Measured and rated data

a. Definitions in accordance with EN 14511

The definitions of the following items, used in this RS, are given in EN 14511:2013 & prEN14511:2018.

  • Cooling Capacity (Pc)
  • Heating Capacity (Ph)
  • Total Power Input (Pe(c) or Pe(h))
  • EER, COP

The switch from EN14511:2013 to prEN14511:2018 is detailed below:

b. Definitions in accordance with EN 14825

The definitions of the following items, used in this RS, are given in EN 14825:2016.

  • Part Load ratio
  • Part Load conditions
  • SEER
  • SCOP
Testing Requirements

Standard ratings shall be established at the standard rating conditions specified in section V. All standard ratings shall be verified by tests conducted in accordance with the following standards:

1. Performance testing

EN 14511:2013 or prEN 14511:2018 “Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling”.
Used for:
  • Standard rating points
  • LRcontmin and CcpLRcontmin

EN 14825:2016 "Air conditioners, liquid chilling packages and heat pumps, with electrically driven compressors, for space heating and cooling. Testing and rating at part-load conditions and calculation of seasonal performance”.
Used for:
  • Psb, Pto, Poff, Pck
  • Part Load Conditions in cooling mode
  • Part Load Conditions in heating mode

2. Acoustical testing

EN 12102:2013 “Air conditioners, liquid chilling packages, heat pumps and dehumidifiers with electrically driven compressors for space heating and cooling - Measurement of airbone noise - Determination of the sound power level”.
Rating requirements

Performance ratings claimed by manufacturers shall be verified by tests performed in one of Eurovent Certita Certification Independent Laboratories or in Participant Laboratory (see IV.3).. The following specifications will be used during the tests:

  • Test unit shall be installed with vertical or horizontal airflow in accordance with the manufacturer’s specifications
  • No fresh air shall be used for rating, neither in cooling, nor in heating.
  • The operating conditions shall be used following the Table 1.
  • Allowable deviations from set values are given in EN 14511:2013 or prEN 14511:2018.
  • Testing shall be carried without mixing damper.
  • The nominal airflow rate and the external static pressure (ESP) given by the manufacturer shall be measured.

* For units designated for cooling mode, the water flow rate obtained during the test at standard rating conditions in cooling is used.
** Same airflow and same available pressure as for the thermal test shall be used.

Indoor airflow shall be in relation with the cooling capacity and used also for the heating mode.

Part-load rating conditions for cooling and heating mode

For each part load conditions, it is possible to vary the air flow of the machine.
Only the damper setting cannot be changed.

Participant will provide a specific procedure to set each part load (RPM or standard airflow…). Without specific procedure, if only the standard flow is declared by Participant for example, the lab will carry out a specific airflow test to determine it.

The following performance characteristics shall be certified and verified by tests:

    a) Total Cooling Capacity
    b) Heating Capacity
    c) EER
    d) COP
    e) Eurovent Energy Efficiency class (cooling and heating)

Energy Efficiency Classification

The purpose of Eurovent Certita Certification Energy Efficiency Classes is to simplify the selection of the best units for each type of Rooftops. The classification is entirely voluntary, not related to any European Directive. The energy efficiency of Rooftops is designated by “Eurovent Certita Certification Class A” or “Eurovent Certita Certification Class B” in catalogues and in the Eurovent Certita Certification Directory of Certified Products. Based on existing units presented to Eurovent Certita Certification the following limits between classes are defined:
