junk article spewing marketing materials and hearsay without doing any testing and measurement for proof.
literally spam.



minus sine is loss.
how can hitachi lie like this?
to their credit, normies are dumb and they don't use that pic anymore.
but pretty sure acdc is in spm.

Depends on the place u r using .

Inverter concept in a simplified version :

Inverter Compressor can work from 10 % of Cooling load to 100 % load . At 100 % cooling load, the power requirement is slightly higher than a non inverter version . The savings occur when , your cooling load is not as high allowing the unit to run at part load . This is the moment where energy savings occur .

Non inverter concept :

Non inverter compressor runs at 2 points . O% load and 100 % load . When u switch on , compressor will run at 100 % . When desired room condition is meet , compressor will continuesly run until room temperature continue to drop ( maybe thermostat detects , room below 18 deg c ) , where it will cut off compressor and wait the room to hit 25 deg C before starting to run the compressor back .

So , if you wish to know where is suitable to use inverter : 

Your bedrooms : USE INVERTER . Unless u r undersizing the ur DX Split . if ur room height is standard 2 m tall with all windows covered by curtains , you may apply 55 btu/hr per sqft .
Living room :

Use non inverter. Most houses usually undersize the living room dx split . It's meant for spot cooling . Even when u use inverter compressor , the savings doesnt take place cos your unit will end up running at 100 % anyway .

I hope this clarifies your request and kindly feel free to contact me if you need further explanation .

in terms of brand to go for :

Hands down to mitsubishi electric and hitachi . Dont fall for Daikin / Heavy industry / Midea / Gree / Trane / Panasonic / Haier / Jalan Pasar split .

This is my personal opinion after using all these brands . Mitsubishi Electric is considered the best  .
