Ten of thousand of offices, shops are using non-inverter air-cond for more than 8~10 hours out there.
So they turn on 3 hours?
or they are stupid to install non-inverter?
No
Why?
Because there won't be much saving by using inverter air-cond in those environmenet, as people go in and out frequently that resulted loss of cool air frequently, and the air-cond won't able to achieve desired temp like 23c, whereby the advantage of inverter air-cond won't be significant.
Despite pages and pages explaining how inverter works, and how the saving come from, it seems still can get a grasp of the understanding on the inverter mechanism.
Inverter /= automatic save current.
It depended on how it works, and being used.
Undersize air-cond, room that can't properly heat insulated, or loss of heat, aka cool air can't properly contained within the room, you won't see the saving from inverter.
As when inverter is full blast or running 100% time, the electricity consumption is as same as non-inverter.
Look at the label of electricity consumption of inverter compressor, the wattage needed by inverter is as same as non-inverter.

A: as for inverter should draw much more power consumption than non inverter, cause from inverter is offer to variable speed & capacity of cooling.
Normal 1hp inverter can able to achieve from 8500-12000 max Btu, is depend your fan & temperature preset.
Look at the label of electricity consumption of inverter compressor, the wattage needed by inverter is as same as non-inverter.
A: inverter have part loan after the temperature reaching may runs lower or slower speed of outdoor unit, even at night time the noise also keep as low than day time.
