Yesterday I went to an a/c shop. The salesperson told me that the gas for non-inverter a/c will be phased out by the government by 2020. So she encouraged me to buy the inverter type.

Can anyone confirm this is true?

Yes that is true

There is a calculation of Inverter for energy savings getting smaller horse is not equal to savings of electricity... your Inverter may not able to cool the room down and run at max all the time, meaning more electric needed and your inverter board and motor will kaput faster...

How inverter work is to cool the room as fast as posibble and slow down the compressor to maintain... if too small of compressor they cannot cool the room down making the compressor running at MAX...

not true. it's 2030 around the globe

Like common Japan & M'sia brand was stopping for R22 already.

Just left the China & cheap brand still runing for R22 until stocks last while

Like film days for those ppls all playing films DSLR in manual

Now all digital but the films no place to wash.

cannot compare films. films more expensive. r22 is cheaper of course still buy r22 now. r410a cost maintenance and freon double.

Honestly R22 & R410a also same don't have any maintenance, just bought a turbo car may high maintenance

when talking about inverter vs non inverter, you guys here mainly only focus on energy saving without looking to other aspect.

I choose inverter becos i want more comfortable condition. I'm a person who actually scare of cold, anything <25-26 i will feel too cold. So normally when i turn ON aircond, mostly i will set 26~28'C only. For non inverter aircomd, when the temp reach 26'C, it cut off. It will only turn ON after temp rise few degree above, and that's the period it make me so uncomfortable. I normally can't sleep well in non-inverter aircond room.

Now you realised

2020
already bought new aircond gua

Yep I notice Inverter aircond temperature very very stable.... very comfortable to sleep

Actually the power saving mainly contributed by the BLDC (BrushLess DC) motor used rather than the inverter circuit. Switching from normal DC/AC motor into BLDC alone already can increase efficiency around 30%, another few percent is depends on the software optimization during HEX bridge switching.

So actually the term 'inverter' used was quite misleading in my opinion, becos the main character is actually a BLDC motor.

so, can this BLDC motor use in non-inverter aircond?

No. BLDC motor need controller board with MCU to fire the correct sequence.

Thanks for the knowledge.
Just, maybe then we can called it inverter system, not just a circuit.

Such as gas like order model were R22 who ever there's no ppl to trying from R22 converted into R410a.

Cause nowadays Aircon not too expansive the cost just +/- slighly lower price than smart phone.

What ever MFGs made we just using at all

coolkwc, sounds like intuitively you've mastered the art of comfortable cooling. In a way your right in the observation. The cut in and cut out of non inverters are actually harmful. Blast until past below set point cut out. When temp raises above n degree past set point, cut in again. Repeat. The occupant is subjected to such unnatural cooling and the torturous heat buildup that many naturally will turn the AC to 23-24-and then just before sleeping, turn it off but leave fan on.

Coupled that with no self cleaning feature and no ionizer, this becomes prefect set up for incubating mould. After a while many still wonder why their nose run and get sore throat.

Get a hygrometer in the room. AC should maintain it between 60-65% RH. Any lower would be dehydrating. That means need drink more water.

Using 1 whole night will have humidity of 40-50% or lower, depends how low the temperature set.
Running nose, sore throat and nose bleeding(worst case) are due to exposed to prolong period of low humidity environment.
Some old timers that still using old air cond never have much respiratory issues as they only turn the air cond on for few hours. But younger generations that are using new tech air cond for prolong hours do have some respiratory issues.

Actually once come to old age should more concern about comfort than saving energy with non inverter at all

non inverter also comfort liao..
