for a 1hp aircon, is it better to get an inverter aircon or non-inverter aircon? in terms of cost of operation, cooling etc.

i see. looks like normal is much better for home use.

Depends where u place it. If in living room where doors keep open n close, ur inverter is pointless. If in room higher hp inverter can make ur room become cold faster thus ur aircon no need to work that hard and so less electricity consumption. Ur inverter can function at its optimum.

inverter, good for long term usage.
save cost/electricity bc u do not know what is ur usage in the future, might be more might be less.

if you are setting your AC on 16c all the time, then inverter aircon will not show any advantage to you.
better have a look on AC with R32 coolant first.

Inverter?
Gas mahal.Service mahal. Install also mahal

1. No such thing as inverter rosak is not fixable. Even non-inverter if major failure can throw away.
2. Gas mahal? Inverter and non-inverter can use same gas which is either R22, R410A, and R32. And R410A and R32 is more expensive than R22 because they are better, more efficient. But R22 gas will be banned in next few years because its harmful to the environment. R410A is widely used now, R32 is the future.
3. Service mahal? Why? Inverter and non-inverter only difference is extra electronic controller on the outdoor. Why the fark your serviceman charge more? Did they cleanup the electronic PCB also? I dont think so. So you kena con coz u r dumb dumb.
4. Why install mahal? Again you kena con. Installing inverter and non-inverter technically is same. Inverter might need 1 extra core wire between indoor and outdoor unit, but it is not a major problem for installation.

I paid rm170 a few months ago to install r32 inverter aircon.

Can you pm the technician no?

Thank you.

cheap if they pasang on high-rise residental

Expert ni,
Please quote me the price of servicing inverter 1.5hp aircon sifu. I expecting the same price as non inverter k

Be a wise consumer. Before buy research first. Almost everyone in Msia has internet access and mobile phone, can do simple google.
And if not sure don't simply spread stories that this is bad, that is bad. Its like spreading stupidness worldwide.
Yes not all service guy is honest, so you got to find legit reputable service guy.
Inverter is not even latest tech, it was invented in 80s and widely used since 90s. You dont have to be expert in AC, just read more.

Biasa la, /k selalu ada orang ini machiam.

ini bodo

inverter got nothing to do with gas
installation also same as non inverter

depends on what needs servicing la.

Buy r32 coolant. Daikin and mitsubishi have them.
Inverter doesn't matter.

Inverter only good if you run it at 0.5hp

lol........ini bodo

No you are.
What do you think an inverter is?

1hp = 745. 7 watts.

1) How much power a 1hp non inverter ac use in an hour if it runs at 1hp?


2) How much power a 1hp inverter ac use in an hour if it runs at 1hp?

R32 is the best. Using it at my hall. Cooling is much faster. Dry mode at 25-26° oso cool enough

Brand i'm using : daikin. I ithink only daikin use r32 gas

inverter slow to cool room but use less power for long usage

This post has been edited by Phoenix_KL: Jan 31 2019, 01:54 AM

Is this even a question?

This post has been edited by Doraku: Jan 31 2019, 02:34 AM

take tis misleading graph 4 example, the non inverter loss is actually misleading, it is a plus, a saving since it use less energy
lets compare a 1300 watt inverter & non inverter 1300 watt & same HP & same room size

- if u turn on inverter it is going to run at 1300 watt and once room temperature is set,
the aircon compressor is going 2 run at low speed using less energy to keep the temperature set,
assume it use 650 watt continuously to do tat, so the graph is correct

- for normal aircon same it will run at 1300 watt and once room temperature is set,
the compressor stop only the internal using fan is running which uses even less energy assume 50 watt, celling fan is 75 watt
so it use 50 watt continuously till the temperature increase till a point, whn temperature increase compressor run at 1300 watt again

so how does a inverter save moneh, whn the temperature keep fluctuating
like u hard core gaming inside the room or mining bitcoin or like a sohai keep walk in out
it save u moneh, since it just run at 650 watt constantly to keep the temperature
not like a normal aircon as whn it run at 1300 watt, the spike overhead cost will be incurred
but to say inverter will only run at 650 watt is also misleading
bcauz the compressor will rev up to max 1300 watt if the room temperature changes is high

why inverter does not save ur moneh but actually cost u more moneh,
whn u on during sleep, temperature will not be fluctuating so much
especially u set 25 degree or 26 degree where the difference with outside temperature is not much
whn the compressor idling it just use 50 watt to run the internal fan only
so whn u look at the chart the loss it is actually saving u moneh where during tis time inverter aircon is running at 650watt constant

so y will u choose inverter, comfort & if u on the aircon for long hours especially during the day
u choose non inverter only whn u on during hot day and for ur sleep only

n bery pro ppl do choose slightly bigger hp like 1.5hp where 1hp is sufficient whn buying non-inverter aircon 4 sleep onli
tis is bcauz on its wattage increase of 1hp to 1.5hp is bery little but the time taken to cold & circulate cold air is drastically decreased
making the compressor enter idle situation faster there4 saving moneh, but u have 2 compare spec & brand ady troublesome

If switching from 1 hp non inveter to 1 hp inverter aircon, the piping connection to outside need to redo or can use existing piping without modifcation?

for my understanding r410a more higher pressure than r22 gas which r410 using synthetic oil r22 use mineral oil , which mean r410a above need thicker copper pipe which mean more expensive during installation ignore pcb blah technology those things same like other shiit

i wonder what is that extra core wire i thought all standard 1HP ac include inverter should be enough 1 life 1 natural and 1 earth since they are not something so BIG that need 2 phase or 3 phase electrical to run

most ac engineer once clean up they dont typical doing a vacum before gas release back to indoor unit which point less unless those really professional is another story but without a faulty AC where to business
im not AC service or engineer just understand some basic theory

basically yeah forgot return line or out line the thick one need thicker copper pipe if your existing AC are using R22 gas if your existing AC are r410 i belive there are no modification for the copper piping side
just blow out the existing from the pipe vacuum and install

i can say both inverter shit and not inverter shit using same 800w max
only different are both 1500cc N/A is like your car engine the higher rpm you use the more fuel you burn
inverter something like you driving your car maintain the rpm below 2k which you can go lebih jauh and fuel saving

non inverter will use more power consumption during kick in is like if your engine having problem you keep start eventually your battery go dead
but if you open your low light can maintain very long hour

or now days a lot modern cordless power tool some brush less some brush motor some dc motor , sure brush less power tool last longer than compare to brush motor brush motor when you press they are some much
sparkling happen on the armature back side those are power loss if im right LOL

conclusion the higher rpm compressor go the more power consumption inverter once reach optimum temp it will drop the compressor rpm like 1k or less to maintain your preference temp i assume max rpm 6k at 1k rpm only use 133watts but i have no idea per minute or per hour i fail on matt

actually when you purchase the AC inside there are warranty card and some random manual actually a lot , inside mention a lot of thing but most user they don't read , standard branded or popular AC out there compressor are 5 year warranty only the compressor 1st year only cover moving part like fan heat ex-changer or some people call outdoor coil , your indoor unit and the remaining part within 1 year any part faulty official technician come and replace totally FOC

after 2nd year if you compressor faulty totally cannot run not cold not an excuse wont be able to claim official 1 to 1 exchange compressor to you but not included labor , official roughly cost 1.2k 3rd party typical A/C guy cost 450

I just use normal. Cheap one I can get. Panasonic. Wanted Daikin but freaking expensive so not worth it

this is true actually
yeah installation are same only difference in copper piping for 1hp r410a ac material use thicker than what r22 needed since r410a gas higher pressure than r22
since is official requirement if fail during official technician verify they wont let you claim anything

If u on 24-26 in a room enclosed, then inverter. Slow to cool? Max it when turn on then adjust it to desired temperature.

Open area, 20° below then normal one enough

i hear many people said inverter save if use more than 8 hours. and if rosak throw throw.
bought my panasonic inverter 1.0HP still working fine until today. bought it in 2012 during my first baby born. its already almost 7 years. my baby born in march 2012.
electricity also cheap. hardly reach RM100 per month (during hot season) sometimes RM40-RM50 only (normal season). (this amount include with my other electric device, i got cockoo water filter, Sharp refrigerator, LG washing machine. i dont have Desktop Computer at home. only use laptop. my wife also use laptop only.

but yeah i regularly service my aircond myself. just clean the filter. the deep service dont know how.

but i hear samsung 8 pole inverter aircond much saving electricity. if my panasonic inverter rosak i want to try samsung 8-pole pulak, with smart wife features too.

Mak aku ada beli satu inverter for her room... Samsung brand i think...

Fucking piece of shit... Lambat gila nak sejuk.

Normal lagi bagus.

But could be also because that time inverter baru introduced so maybe nowadays inverter better... I dunno


But i think everything that is "eco friendly" = worst quality than normal un-eco friendly

Those who said “slow to cool” - I really don’t understand. I turn on mine like immediately I can feel cold already. My temp I set 27°C summore and in the afternoon. I’m the type takut hot wan

Yes pana inverter

Lel.
R22 aircon no longer in production. So comparing r22 and r410a is pointless.
Gas type used got nothing to do whether inverter or not.

if u not always on ur aircond dun fall in this inverter tech. trap , there are not significant saving about with or without inverter if u not use ur aircond more than 10 hour continuously

This post has been edited by bereev: Jan 31 2019, 07:59 AM

Lel I never reply you a single word inverter I only reply you different between the gas , yeah r22 no longer production but without r22 where got r410a without r410a where got r32 lel ...

average usage per day is....?

So for shop and office, better to pasang 1.5hp inverter x 2 or pasang 1 strong 2.5hp/3hp inverter?

aircond shop recommend me to pasang inverter coz for shop/office normally pasang aircond 24/7, so inverter can save electric bills a lot...true or not?

another question

1.5hp non inverter r32 aircond vs old model 1.5hp inverter r410a which one is more electric saving?

r32 efficient in terms of cooling or efficient in power saving?

I use inverter 1.5hp for my living room. Temperature set at around 26Deg. Just nice cooling effect, comfortable, and stable temperature.

No noisy compressor kick in and out. I can barely hear it when I am outdoor nearby the compressor.

Operate around 8 hours daily and my tnb bill is not much different and about the same compared to the time before i install the aircond.

Noticed inverter coldness is more soothing whereas the old type r22 is more to sharpingly cold...

Once you get through the first 20-30mins of turning the aircond, you start saving. Doesn't matter how long you on it for. The longer you on it for, the more you save. The first 30 mins is when the AC tries to cool the room ASAP and then maintain subsequently which is where the power saving comes in.

Stupid. Starting amp for non inverter is what causes high usage of electricity.

You welkam....sama sama we save!

sifu, which brand more tahan lasak? For home use only

If room use get inverter. If living or dining area then non-inverter. Don't get R410a go for R32. R410a is a transition gas which contain 50% of R32 and other gas. Service cost for both will be the same, but parts, inverter will be more expensive but not to the extend of need to throw away of your AC once spoil. Daikin, Acson and Panasonic is good, since they are made in Malaysia, the spare parts is cheaper and easily available.

If you have money any Japanese brand except Sharp (not sure how is their quality after China bought some their shares) is good to go. Panasonic, DAIKIN, Mitsubishi, Toshiba.

If tight budget, you can go for Gree or Media. These 2 are top brand in China but personally for AC I prefer Gree because they seems to focus on AC product.

And get an inverter, and try to learn how to set your AC temperature. 24 C - 25 C is the ideal comfort zone for human.

Nothing to do with the gas. This is because the compressor on off.

Not sure but the air coldness of the non inverter machiam colder than the inverter when u put ur face direct to the blower

I have bad experience with Samsung... 2 of my inverter Samsung died (triangle model, 3 years old only). Dead outdoor unit controller board. They quote RM600 to replace it.

Care to elaborate why avoid Daikin / Panasonic?

Inverter?

mine : HITACHI 1.0HP INVERTER R32 RAS-VX10CJ, already meet my requirement.

6-7 hours only. we set timer. mostly open at night only. and weekend. but weekend usually i tk my family jalan2 luar..lol

oh really.. 3 years still new..wow. im very tempting to change to samsung smart aircond. but since my panasonic inverter still working fine. only the white cover already change to a bit yellowish..its a waste of money.
samsung warranty 1 years only right? aww sad la.

outdoor unit control box? your outdoor unit installed exposed to rain/sun? mine the control unit installed inside the car parking roof. its 100% avoid from direct sunlight and rain.

7 years used. only 1 time top up new gas. every months clean the filter. can get better air and better power consumption.

Many thanks, that's really help! ~

Guys, i have an apartment unit right on the beach. It's a small unit, around 700 square feet with 2 small rooms.

I am hoping to put 1 good unit to cool the whole house at one go, 24/7 whenever I go back there on weekends.

Can advice me?

Thanks a million!

not anymore, tat is old tech ady, if u still using those aircon better change

so now siapa yg bodoh siapa yang pandai? xpasti mana yg betul mna yang salah ni

Yup... I dumped that Samsung units (too expensive to repair), installed Daikin inverter. All good The Daikin installer doesn't want that Samsung unit (the indoor unit still shiny and clean), not even for RM50 each.

I also have Panasonic Econavi Inverter. Had been working well since 2013

FYI, the outdoor (all 3) unit is not directly exposed to rain... it under awning / window shade.

Lel. All motors have inrush current.

Is it becos of the board has been shorted/fried?
I heard people recommending spray a layer of pcb coating, to minimise exposure to moisture & creatures (lizard) getting onto board and short he circuits.

finally a proper explanation...
+1 to this...

Not sure why the PCB fried. Extra coating what so ever - that the responsibility of the manufacturer... not the buyer. It's supposed to last a considerable time. The outdoor unit should work even under direct sun / rain.

That's the problem.... manufacturers doesn't not assume this responsibility.

i belip wat he said is those bery old aircon with no / bery small capacitor & slow step up motor & switching etc
4get the exact term they use whn explain 2 me, ofcauz i'm not saying it does not eliminate it but rather reduce it
whn u compare those with new inverter tech + all those; ofcauz the current pull consumption is high & not stable
but as wat the aircon guy explain 2 me, new non inverter is bery efficient ady as it include those as well

not saying inverter does not save electric but it depend on situation & it some case might cost more
the saving of inverter is very small to might cost u more especially whn u c ppl said 25-27 degree & in mid turn off & on like tat
u onli c the difference whn u on at 23 degree below to 15 degree & for long hours

i actually experience it with my cassette aircon, inverter & non inverter
where the inverter actually cost more to run whn i set it at 25 degree & onli notice the saving whn i set it at 23 degree

but cost aside another advantage of inverter is the comfort,
no sudden cold & hot, i would choose it over non inverter anytime regardless of cost

Dah dah dah.

Just admit that you are talking shit.

Depending on the temperature set point and AC size, if your set point is just at switch over point, inverter AC might cost more than non inverter as the unit is going on and off all the time.

The heat removal capacity of the AC are also as important.

Met a case where the AC is running at max all the time due to under sized and in that kind of situation, inverter or no inverter will not give any difference as they are running full load all the time.

Too little is never enough and too much of a good thing can be bad.

afaik is 5hrs?
it's 8hrs??

Simple explanation are the lower RPM the lower Watt use if ac max power are 800watt and the higher BTU the faster they cold when purchase ac same price ignore those purifier PCB blah coated shit Fancy thing looks for BTU instead

Most faulty ac when repair they are either change the compressor or add on More higher capacitor if not a logical board issue, due to when compressor cylinder damage the default power to push are limited happen sudden stop or power Trip sometime

when using bigger capacitor just increase more power into compressor push the limitations for temporary or force compressor to run eventually we call over loaded in the end your compressor using more power more power hungry more hotter and your 2.5mm house wiring could burn or melted then could be damage other wiring as well

My shop have 4 ac 2 1.5hp 1 1hp and 1 2hp after replace same hp but non inverter just a regular r410a all down light change to led

Every month my tnb Bill only save rm150 to 200 compare to RM 850 or 900

Or you can try add a bigger capacitor into to your regular ceiling fan it will spin very fast like no tomorrow after 10 minutes fan motor eventually smoke and fire then power Trip since all motor have a maximum power limitations

more like u have nothing 2 say, rather thn shit

This post has been edited by junsheng: Jan 31 2019, 08:25 PM

i do knw abt these, wat i said is they implement the capacitor switching & control the motor speed at start
to regulate switch on surge & reactive power

Such a general statement

Mcm cakap not all keyboard warrior in k is honest

Kek

All this technology invented Long time ago I guess is just that time to big and bulky and expensive now technology improvement able make Small enough to fit so we can just actually ignore it let engineer do their job I guess we just spending

Old school just on and off concept is like some power tools your table fan ceiling fan which can control your fan speed or motor speed or dimmable light With few simple trick

Not everything created equal pro and con like when I using power tools doing some work need minimum speed yeah I get my job done but drawback my motor hotter than running in full speed since the attachment fan blades only perform optimal cooling in full speed

Is like there are nothing wrong with engine running too rich or too lean which only difference bad fc lack performance but make your engine cooler but optimum you get both better but engine hotter

ady said these ady well known, where last time these component is not included in normal housing ac last time
the more 2 said is better power factor, which the reactive power is now regulated well
better power factor = more efficient = save more electric,
& very huge noticeable difference if the electric rate include reactive power penalty

switch on surge & motor step up control is just another add on, since i belip the parts have bcum cheaper
tis is insignificant to saving electric cost, n y u keep talking abt engin heat
capacitor can be used to assist motor, but it can used to regulate reactive power also

it has gone out of topic, i just want 2 said old ac does not have these
where new ac like inverter & non inverter does include these
2 compare inverter with old ac ofcauz it is not fair; 2 previous ppl tat said so

yeah. me panasonic eco navi inverter too bro. so far so good. i bought in 2012.

if we need to argue this much to get convinced

for sure it's not worth it

wei dupe, lu realise tak a standard door size is 2.1m? who the hell has a 2 meter high room la ko ingat ni jepon ke?

ts so many concern, time and head ache. in the end save only 20 ringgits per month, better spend more time on earning money.

Just found after googling, since manual dont know throw where, the gas is R22, so if buy new aircon whether inverter or non inverter, need change piping or not?

I mean need to drill another hole or can use existing hole in wall for piping?

If 1hp actually no need because the pipe is small size (1/4" and 3/8") and the thickness still able to take the pressure. Just make sure ask the installer flushed the pipe with R410a to get rid of the old compressor oil which is not compatible with new refrigerant.

So can use both R32 and R410a gas aircon, me not familiar with gas?

So can use both inverter and non inverter aircon too?

Yes can use both. I suggest you go for R32, which is a more superior gas (R410a is a transition gas). I know Daikin R32 1 and 1.5 hp are using the same pipe size. So if your old ac is 1hp R22, you can actually have the option to install 1 or 1.5hp R32 AC. Just make sure flush the old pipes, R22 compressor oil mixed with R32 or R410a gas is a big no no.

My main concern are the componets outside prompt to direct sunlight, eg compressor, connections etc. Thinking towards noninverter 1 hp models aircon, since noninverter models have less components outside compare to inverter models.

Now my brain was busy googling for models from different brands.

Any recommended noninverter 1 hp models?

Outdoor unit are designed to cater for outdoor conditions, don't worry too much about it. Inverter do have more board at outdoor, but usually the board damaged due to voltage fluctuation. If you use for bedroom on daily basis, I believe inverter is still the best choice. Not only saving on electricity but inverter AC also able to maintain the room temperature better. Just make sure you go for Panasonic and Daikin for cheaper parts if anything happens.

If you want non inverter then can go for Daikin R32.

If your existing pipes are short and no conceal, just use new pipe. Else can stick with existing pipes.

Thinking towards 1.0 hp daikin currently but not sure getting inverter or noninverter.
