- Cooling power or yield
is a climate control system's capacity of cooling, and it is a 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 catalogs provided by manufacturers, this is given in Watt (W) or KiloWatt (kW = 1000xWatt). Catalogs 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 gallons or liters per hour.
- 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).
