The energy efficiency class and 'a subdivision of the scale of consumption of household appliances by the European Union normative.
It indicates the ratio between energy consumed and the energy yield from an air conditioner as letters from A to G, where Class A is 'to indicate that the equipment to equal' power output, has reduced fuel consumption. This means that an air conditioner
CLASS A has a higher return to a lower class. The words
double class A and 'used to define air conditioner with heat pump, which are Cless A is for heating and for cooling.
inverter technology allows you to vary the power of the machine to a minimum to a maximum of eliminating the constant stops and starts the engine (air conditioners classic on-off).
In practice, the machine cools the room quickly pushing on, throttle and then modulates the power to a minimal level to maintain the temperature.
This technology provides energy savings up to 50% compared to traditional on-off.
Therefore, even if an inverter air conditioning costs something more 'than an air conditioner on-off ClassA, this higher cost is recovered in a short time to cut costs of electricity.
