Glossary

  • Cooling power or yield

    is a climate control system's capacity of cooling, and it is fundamental factor when choosing your air conditioner. This is measured in Btu/h (British Thermal Unit/hour), frig/h (frigorie/hour) or W (Watt).

  • Power absorbed or consumption

    is the air conditioner's power consumption. In catalogues provided by manufacturers, this is given in Watt (W) or KiloWatt (kW = 1000xWatt). Catalogues usually also include the current used in Ampere (A).

  • E.E.R. (Energy Efficiency Ratio)

    is a numerical coefficient that indicates the efficiency or yield of a climate control system. It is a pure, dimensionless number obtained from the ratio between cooling power and absorbed power, and it determines the unit's Energy Efficiency Class.

  • Thermal power

    is the power yielded by the machine when operating as heat pump. It is measured in W or in Btu/h.

  • C.O.P. (Coefficient Of Performance)

    is the equivalent of E.E.R. for heating. A numerical coefficient that indicates the efficiency or yield of a climate control system in heat pump mode. It is a pure, dimensionless number obtained from the ratio between the heating power yielded and the power used.

  • Air flow

    is the quantity of air that the air conditioner can have pass through during the air "treatment" period and is measured in cubic metres per hour (m?/h).

  • Dehumidification capacity

    is the quantity of water that the climate control system removes from the air in the dehumidification process. It is generally expressed in litres per hour (l/h).

  • Noise level

    is the noise produced by the climate control system during normal operation; it is measured in decibels dB(A).

  • Rated temperature

    is the range of temperature within which the air conditioner can operate. It is measured in degrees °C (Celsius) or °F (Fahrenheit).
