This certification programme is divided into three sub-programmes:
This programme applies to factory-made units intended to produce cooled air for comfort air conditioning (AC1, AC2, AC3). It also applies to units intended for both cooling and heating by reversing the cycle.
Are included in the AC1 scope:
Are excluded from the AC1 scope:
Are included in the AC2 and AC3 scopes:
Capacity | 12 kW ≤ capacity < 30 kW | 30 kW ≤ capacity < 50 kW | capacity ≥ 50 |
Number of indoor units | 4 | 6 | 8 |
Each combination is composed by one outdoor unit (and its declared values) and associated indoor units:
Are excluded from the AC2 & AC3 scope:
Participating Companies must certify all production models within the scope of the programme they enter. However concerning multi-split air conditioners only systems with two indoor units are included.
Air conditioner
A device capable of cooling or heating, or both, indoor air, using a vapour compression cycle driven by an electric compressor, including air conditioners that provide additional functionalities such as dehumidification, air purification, ventilation or supplemental air heating by means of electric resistance heating, as well as appliances that may use water (either condensate water that is formed on the evaporator side or externally added water) for evaporation on the condenser, provided that the device is also able to function without the use of additional water, using air only.
Heat pump
Encased assembly or assemblies designed as a unit, using a vapour compression cycle driven by an electric compressor, to provide delivery of heat.
Comfort air conditioner or heat pump
Air conditioner or heat pump to satisfy the comfort requirements of the occupants of the air conditioned room.
Packaged unit
factory assembly of components of refrigeration system fixed on a common mounting to form a discrete unit.
Single split unit
Factory assembly of components of refrigeration system fixed on two mountings to form a discrete matched functional unit.
Single-duct air conditioner
Air conditioner in which, during cooling or heating, the condenser (or evaporator) intake air is introduced from the space containing the unit and discharged outside this space.
Double-duct air conditioner
Air conditioner in which, during cooling or heating, the condenser (or evaporator) intake air is introduced from the outdoor environment to the unit by a duct and rejected to the outdoor environment by a second duct, and which is placed wholly inside the space to be conditioned, near a wall.
Total cooling capacity, Pc [kW]
Heat removed by the air conditioner from air per period of time.
Heating capacity, Ph [kW]
Heat supplied by the reverse cycle air conditioner to air per period of time.
Effective power input, Pe [kW]
Average electrical power input to the unit, within the defined interval of time, obtained from:
A-weighted sound power level, Lw [db(A)]
A single figure on a specific scale which can be related to the subjective assessment of the loudness of a noise.
