SCOPE OF THE PROGRAMME

The Eurovent Certified Performance (ECP) programme scope for Rooftops (RT) applies to air-to-air rooftops and water-to-air rooftops, rated up to 200 kW in cooling capacity, as defined in EN 14511:2018.

The programme is divided into four sub-programmes:

  • One mandatory sub-programme: Air-to-air units up to 100 kW
  • Three optional sub-programmes:
    • Air-to-air rooftops from 100 kW to 200 kW
    • Water-to-air rooftops up to 200 kW
    • 3 or 4 dampers units.

The following features are not certified:

  • Gas burners
  • Pre-heaters
  • Heaters
  • Additional internal coil
  • Heat recovery (plate, wheels, thermodynamic systems)
  • Exhaust fans
  • Split rooftop
  • Roomtop.

Programme exclusions can be found in the Technical Certification Rules.

CERTIFY-ALL PRINCIPLE

Whenever a company participates in the programme for RT, all products that are promoted by the applicant/participant to end-users, specifiers, trading companies, contractors by means of paper or electronic catalogue, price list or software within the scope of the programme, shall be certified. This is done in accordance with the Technical Certification Rules and includes all models in modular ranges. For the RT programme, the certify-all requirement is applicable for the European market as defined in the Certification Manual (Art. 30).

PRODUCT TYPE

Rooftop units are used for thermal comfort for buildings, usually retail and small commercial applications. Rooftop units are a packaged (all in one) unit, installed externally on rooftops, capable of providing ventilation, cooling and/or heating to a designated space. Rooftop units provide air filtration and purification, as they are fitted with high efficiency air filters to remove harmful particulate matter from the air supplied to the building. Units are intended for use in applications where recirculation of air is acceptable. Additionally, rooftop units may also provide functionalities such as humidity control and free cooling.

In the RT programme, a rooftop unit is defined by the following features:

  • Air-to-air rooftop: Units covered by ErP regulation No 2016/2281 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 evaporator, compressor and condenser are integrated into a single package.
  • Products not reaching the minimum ErP regulation No 2016/2281 requirements can be certified with a clear indication of the intended market as “Non-EU”.

Features of rooftop units according definitions from ErP regulation include:

  • 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 equipped with 2 / 3 or 4 dampers depending on the inclusion (or not) of a heat recovery system.

Products in the RT certified product directory are searchable under the product types air cooled, cooling only and air cooled, reversible.
