If you're planning on using inverter AC in your resto/high foot traffic business. Think twice.

I can't help myself from facepalming whenever I see a restaurant (or any establishment with high foot traffic) equipped with an Inverter air conditioner inside. Apart from being a total waste of money, it just shows how extremely uninformed consumers are of this technology.

Despite dissuading my dad dozens of times from installing inverter cassettes in our restaurant, he still went for it--only to be disappointed because the ROI will take roughly a century (exaggeration) because his monthly electricity bill only dropped by $10 at best.

Did I mention that the three 5 tonner inverter Daikin Roundflow units he got cost more than enough money to renovate the kitchen? Oh and yes, he opted for the self-cleaning option which I think is bollocks.

Endless opening of doors, influx of people, oversized glass windows, bright indoor lights, air drafts from the kitchen and bathroom ventilators -- all these introduce hot, humid air into the room making it difficult/next to impossible for the Inverter AC to cool down the room at the set temperature.

This means the compressor is cranked to full speed all the time. Basically uses the same amount of power a conventional AC would (which also costs 25-30% less than inverter units).

Inverter air conditioners can only achieve power savings once it has stabilized the temperature inside a well sealed room, once the desired temperature is attained, the compressor gradually slows down or slowly ramps up (to maintain temps) which equates to power savings as opposed to cycling on and off at full speed the way conventional ACs do.

Moral: Keep Inverter AC use strictly at home where doors are almost always closed and curtains are always drawn, regular ACs will suit commercial spaces better and more efficiently in most cases because there's no AC-DC power conversion losses.

Needless to say, dad listens to me now and the insanley expensive new air conditioners are self-cleaning after all, we only have to stick in the vacuum cleaner hose every month or so in the dust receptacle to empty em out which is a plus, not exactly mindblowing.
