refer to the graph.

this is normal consumption in my house with 3 bedroom airconds running.

once the temperature reaches saturation point, the usage is about A. around 3.3A (759W)
759 watt is fricking low considering there's 3 aircond running that is rated at 900W+ each.

B is when i decide to go out from my study room and go make coffee.
so B is me making coffee.

then you get C which is higher compared to the saturation point at A because the door is opened, compressor has to be run at higher load to reach back saturation temp.
anyway once the set temp is reached. i turned off the AC to check how much it costs to keep the AC at the temp preset.

the current goes down from 3.69A to 3.05A.
meaning one of the AC is only using (3.69-3.05) * 230V = 0.64A * 230V = 147W

~150W of power to keep the room temp at 26 degrees after the set temp is reached.
so no, you don't need 8 hours of run time for an inverter AC to save energy.

provided that your AC is installed correctly, and there is absolutely no air inside the AC system which will cause the AC to run at reduced efficiency.


this vacuum evacuation process is imperative in ensuring the AC gas line is free from air before the system is charged.
but nobody does it.
