What is the difference between conventional (regular) and inverter aircon

Form Penguin Aircon





A regular aircon uses a single fixed speed compressor and fan motor.  It is either off or on.  On the other hand, an inverter unit uses a variable speed motor that adjusts speed depending on the demand or need.

Thus an inverter unit:

1.  Reaches cool temperature faster;

2.  Is quieter; and is advantageous for sound sleep or in crowded residential areas.

3. Runs with 30% less power.

However, the unit must run at constant temperature, say 21 and not at maximum power

We can see that it is not the most efficient as the solar hybrid unit runs with 40% less power.
