Does inverter aircond really save up electricity compared to non-inverter aircond?

dont make me regret oi

i just bought lg mosquito inverter.. next week install!!!


but the power consumption data is relatively low.. 1762kwh 5 stars compared to some 2500kwh++ with 2 or 3 stars

Go install those bypass/off meter illegal devices, confirm save lel

Save if u on for long hrs. Like more than 5hrs?

https://forum.lowyat.net/topic/2403526

save if use for long duration...if kejap-kejap same ja with non inverter

what device? just tap one line before meter entry = profit..lel

in a long run, yes...but depends on ur usage n pattern of usage oso la

i feel its a scam... especially the panasonic ac... konon la save electricity but the air coming out with the highest fan speed pun macam tarak rasa.. sure la save electricity if this is the case...

What the mosquito inverter does? Turn the mosquito upside down?

save if your room cepat sampai the desired temperature

save if using the air cond for long duration, example from night to morning when you sleep.

It really does saved a bit but you will save significantly if you remove the air-con

Thank you all!

Change the resistor and ic in the meteer sure save a lot

lolzz

lmao

inverter tech is for energy saving nothing got to do with nyamuk la

mosquito away tech from lg what i read is they have some sort of ultrasonic wave shits which hinders mosquitoes..

idk how effective it is.. ill try next week n comment..

Aircon save very little only.

If u wanna save, change your old fridge, that one saved me RM150 per month...

careful these wave dont affect your health in the longrun....

Just like mosquito spray... kena trus mati.... kena human no problem... but if long term exposure cancer kena

yup noted.. hope it has those on off function

I had the same dilemma last year when i was choosing air cond.

What I was told by the air cond technician is that, unless you on the air cond for around 10 hrs or long periods of time, there is no difference between them.

Because from what I understand, inverter saves electricity by maintaining the temperature through constantly cooling and running at low power.

While non inverter air cond maintains the temperature by cooling it down to the desired level, stops cooling and will only start cooling again after the temperature rises to a certain level.

This act of cooling and stopping takes up a lot of electricity, as more electricity is needed to restart the cooling as compared to running the cooling at low power continuously.

Thats what I understand, please correct me if I'm wrong...

So if you're just using for your living room, there should be no need for an inverter. Plus the price difference between inverter and non inverter is not exactly small.

As for brand, my recommendation would be PANASONIC. Its more expensive compare to the rest but each of them have lasted at least 10 yrs before breaking down and requiring extensive repair. When that time came, I just bought a new one...

Currently for my house I bought 5 air cond, all PANASONIC. 3 unit 1.5 hp and 2 unit 1 hp. 2 unit 1.5 hp in the living room and 1 unit 1.5 hp in the master bedrooom. Electric bill stands at around RM200-300, no tampering of my power meter.
My neighbor using dunno what brand, dunno how he use, he is complaining of paying RM800 a month.

And please take note, normal house circuit only can take total 4 hp of air cond running at any one time.

For most users, the saving is negligible and take a long time to breakeven, if it is possible. But looking at nationwide saving, then yes, it help the country by consuming lesser electricity since the cost of changing to inverter aircond is bear by the individuals.

If it really save electricity, the thing you hear will be no money to change to inverter aircond, instead of asking if it really save electricity or government force me to change

Is this true? Can save that much if change fridge? Was thinking about changing aircond to inverter as using from night to morning everyday. It's a 5-6 year old air cond. But fridge is even older than that. So better to change fridge first and see how the power consumption goes?

Thanks.

Definitely fridge u can see more savings... cause fridge on 24/7.

Wow.... LG got inverter air-con with mosquito repeller?

Mosquito repeller using ultrasonic sound existed over 20 years ago but I think it never really works. More like curiosity boom sales only and then rapidly dies off. I bet when LG tested it, they detect no mosquito at the air-con there because the mosquito cannot cope with the air from the blower

According to my aircon service guy, inverter save electric by turning off your compressor, also when start, it will turn up slowly, off again when reach desired temp. Which is why inverter aircon sometimes not cold enough.

Just saw the demo video in showroom, they test it by building 2 connected box with diff aircon 1 with mosquito repel, the other dont have. Then release mosquito into it.

Results show all mosquito run to the box with no mosquito repel aircon.

Oni if use 4 long period of time.

Better to buy an inverter fridge than an aircon, imo.

I think quite save lor.. I use panasonic inverter 1.5hp. Turn on around 12pm until next 6-7am..everyday. My bill got increased rm50-60 only.

I don't no what logic to have a mosquito repel aircon.

Your room is fully close for aircon run. There is no mosquito in the room.

Who the hell will open the door or window with aircon run for whole night sleep ?

For fridge, I think it is not much significant. The saving depends more on how many time the fridge door is opened and closed within the day. The compressor is completely off once the set temperature is reached for conventional fridge. For inverter type the compressor keeps running non-stop though at lower power even when temperature is reached.

I use inverter aircon for 8yrs.

In 8yrs, the electrical saving is already more than enough for me to buy another new aircon + servicing.

Yes, 1 hour ahead I would have the room sprayed with Ridsect already and keep door closed

I was thinking of the same thing.
Maybe it prevents extra mosquito entering the room when aircon is on.
Maybe it "kacau" those mosquito sensor so the mosquito dun kacau u.

Gimmick....

it will save a lot if u only set temp at 25-26 and leave it on for long hours.

Compressor will stop also for inverter fridge. And it save too. I m using it.

thanks for the very useful info

i also dun think it works, else repel mosquito would be too easy

Nope....

I used to have an old fridge.. liek 10 years old....

Then when I have a baby, I need a bigger freezer, so I got a much bigger fridge (so much so that it cannot fit into the kitchen door), so I retired the old fridge....

My monthly electricity bill dropped by 150 on average...

use this for real saving

So, Panasonic or York is better?

A friend installed an inverter (Panasonic Econavi Inverter) Previous bill was 400, after installation he managed a saving of RM100, now bill at 280-320 he said. Normal pattern of usage, after 8pm turn on, 6:30am off.

According to him. He is happy now.

Plus inverter according to the star energy rating also specify a reduction of half the usual power consumption. You definitely can expect a saving.

Though install meter or do some meter trick can save more.. friend house big corner lot 6 bedroom, family hall bedroom all aircond on long hours... Bill every month RM400....

i think the most important thing about ac is to ensure it has the right horsepower for the room size and it is switched to automatic mode.

you see, when the horsepower is just nice, it will be able to cool down the room at a short period of time and with the temperature sensor it will automatically lower down the speed of the ac. hence reduce in the power consumption.

but when the horsepower is insufficient, it will need extra effort to cool down the room hence the additional power consumption.

not sure correct. just my observation as a half bake engineer here... no full time qualify engineer...

yup save compare to non inv.

Looks like I was wrong. It does stop when the temperature is reach. The advantage is that when it runs again, it does not need to run at full power unlike non-inverter type, thus save energy. The power varies according to cooling need

Owh yes, i myself is a GBI certified personal. Refrigerator is the only 1 component in your house that consumes electricity like nobody's business and runs 24/7. It can really eat up a lot of your electricity and if you have that freezer box, it is going to be a lot more expensive.

Thus, an inverte refrigerator, or a 5 star rated refrigerator can really cut consumption. You can notice reduction in consumption straight away.

I think you are right. I'm using inverter type also but never measure because my bill keep increasing because I added more and more appliances

Continously
If u open the air cond more then 8 hour per day get the inverter
If u open the air cond less then 8 hour per day get non-inverter

pm me for best price

i tried with some sort kwh monitor on my panasonic 1hp inverter aircond recently

temperature is the key, if weather hot, room or outdoor temperature are warm

aircond compressor runs harder at very high power draw up to 930W, even if you set your cooling temperature to 25c, it's still running at the same power level try to cool the room, as long your room temperature isnt cool enough below the temperature u set on aircond, your compressor will always work hard and high power cost

most of time if outdoor very warm, compressor not producing cool enough to cool down your room, your aircond will continuously draw high power


Set temperature at 25 or above does not really help to save energy if weather HOT and your room is very warm to cool, it only saves energy when your room temperature is cooled to the specified temperature you set.

Compressor work level depend on the temperature in your room is detected.

Suggestion:
Turn on Aircond, set temperature to 16c, max fan speed, to quick cool your room, after half an hour, then set to the temperature/fan speed you prefer, aircond will work less and save alot energy.

What I think:
-turn fan speed to max only increase like 10-20w from minimum speed
-air conditioner compressor will always high work, high power cost if weather and room temperature is too hot to cool.


my Panasonic 1hp Inverter Airconditioner power consumption:
(16c max fan speed settings)
- day time hot weather 850-930W
- night time 8pm 700-830W
- night time if raining 600-750W
- midnight after 12am 570-650W

Set temperature to 24> has no power consumption difference if weather is hot, and if your room is hard to cool, aircond still work harder try to achieve the specified temperature

1.7 megawatt is low lol.

You touched on a good point...

WHen you use appliances like aircon, air blower, fan... the power draw of min speed and MAX speed... is negligible...

1.5hp or 2hp?

Hello there...

My story,

Got 1hp samsung smart inverter aircond, hitachi inverter fridge, 49 lg tv,

1) use the aircond >8 hours a day plus almost 12 hours if weekend
2) fridge 24/7 on
3) tv 2-3hours daily

My house monthly bill is about rm40-rm45 per month...

+1

Always get the correct cooling capacity for your room. If you like to under spec/size your aircond, either due to budget constrain or you only want your room to be cool;not cold, just use normal aircond.

Yup agreed bro. I always turn my aircond to smart mode, which about 24 C. The compressor will be in halt mode once the temp reached. Then when temp drop, the blower will run again...

I check it with kill the watt meter. Confirm it stop sometime. Silent.

Yes, it run in variable speed. Can hear it the pitch sound high and low.

Bill save a lot.

His is true, but my fan draws 65w. Aircon draws what, 10x that amount? Later will complain power prices go up

What meter are you using for that?

um. what are you talking about.

actually i learn something from frangipani langkawi resort and spa owner when he gave a speech about how eco friendly his resort was.

one of the ways the reduce his resort's power consumption was to cover up or rather have shade over his ac compressors which are mainly outdoor under the sun.

he said just by covering the compressors, he actually saved 20% electricity!

well i couldn't verify it but i think there is no harm trying.

Inverters don't save as much as fans. Fans use around 65w. Even in a best case condition the inverter aircon will use 10x as much

It is a Kill a watt meter.

Check the wattage of your electrical appliance consumption. google it.

not much la. last month was really hot, almost every night i use my 1.5hp inverter and normal 1hp. bill almost rm180.

Cool where did you get one?

If he run 24/7, that is some small reduction. No logic if mainly using at night sleep.

The compressor is actually running hot.

The most effective is, insulate your room. Just think like how the fridge running at low consumption.

amazon uk, ebay, lazada etc.

Becarefull don't get the US model. Voltage different.

Um... why are you comparing Apple to Durian?

Saying Aircon uses more electricity then fans is like the Capt of all Capt Obvious

Isnt the objective of this thread to find ways to cool a room in the cheapest way possible?

What type are you using? I had one but it broke easily.

no, its to compare inverter vs non-inverter aircon

and also i dont think fan can cool a room down to say 24 deg like an aircon. Unless u have some very funky fans.

My panasonic refrigerator cost as low as 40w average,when compressor running, only up to 110w, more power saving than my pc lol

20+ yrs samsung refrigerator average 220W, low is 100+w

Coca cola refrigerator average 495w, low 60w but compressor running time very frequent at 495w, its very high power consumption

My astro, amplifiers 5.1, HDTV plasma average 200-300w floating

You buy from here? I have 1 brought from local. LCD kapot in less than 6mth.

Get from ebay uk. Work find for many yrs. Similar to this http://www.ebay.co.uk/itm/Power-Meter-Ener...a0AAOSw9mFWJgcb

Introvert vs extrovert

kena buka satu hari malan sampai pagi...save rm 0.8-1.20 saja lo.

Which brand? Must buy lol

can i know how many aircons you switched on at the same time ? and for how many hours averagely..

U mean refrigerator?

Panasonic

I mean which model?

Need back home to check

You need to know the daily and monthly consumption.

This watt doesn't tell much the consumption. Ex. what is the Panasonic fridge capacity perconsumption.

Correct me if I am wrong, I just installed an inverter 2HP panasonic in a 400 sqft studio room.
I was thinking for 1.0 or 1.5 HP. but the technician told me if the room is hard to cool down, your compressor will eats up alot of power in order to cool down the room to your desired temperature. However if you use bigger HP, it makes the room cool faster and once it goes down to your temperature u set, compressor will slow down too, meaning it will eat less energy. So I think it depends on what HP you use for how big your space is.

Yes and no. If its constantly on then yes else before the inverter function kick in and you off the aircond it wont save any electricity.

I think it only work with aircond with sensor?

lmao almost everyone on that tered is talking right out of their asses

Size the aircond accordingly to room size.
it better to size it a bit higher so that invertor aircond will perform at top notch performance.

Currently i am testing 2HP Daikin Invertor with setting at 24C & 25C.
At 25C, average daily kw consumption is 6 to 8 KW.

Daily running whisper with moderate blowing distance up to max average 12feet.
Experiment with 18" KDK to distribute more cooler air further will ONLY increase your kW at almost double digit aka 16Kw consumption.

It show that using Fan to aid cool air distribution doesn't work well with Invertor AIrcond.
Currently just install 2nd Daikin 2HP

I am part of my company ENergy Saving Team aim to reduce "electricity billing" for the whole company.

(1) LED flourescent indeed can save
(2) Now researching Invertor Aircond.

If set to Dry mode can save or not?
I set mine to 28°C and Dry mode, still damn cold
Can use your meter test for me...

I didnt write down when I used wattage monitor to monitor


It does count real time wattage drawn, kwh, and cost per day, monitor continuously for days, the RM cost is really low

The refrigerator has stored stuff 80% of its capacity, and its slightly wider version of regular large refrigerator

I recommend you to buy Kill A Watt power meter



http://www.p3international.com/products/p4400.html

Simply connect these appliances to the Kill A Watt®, and it will assess how efficient they really are. Large LCD display will count consumption by the Kilowatt-hour, same as your local utility. You can calculate your electrical expenses by the day, week, month, even an entire year. Also check the quality of your power by monitoring Voltage, Line Frequency, and Power Factor. Now you´ll know if it is time for a new refrigerator or if that old air conditioner is still saving you money.

---------

I think lazada.com.my ada. under RM 150

Can save electricity but for sure not as high as 50% like those marketing scams say.

At most I think about 25 ~ 35% only.

My 1.0 HP Daikin Inverter air cond uses about 450W per hour (RM 27 per month if use for 7 hours per day). Ever switched it on for 7 hours during night time, then next morning checked my electricity meter, it increases 3 kWh.

Fridge not yet moved in, so the reading is accurate (night time only one LED light and air con switched on).

Yes, im using something like this, very useful and quite accurate, if comparing to the TNB meter, kwh monitored nearly same,

Tried turn everything off and unplugged all things in my house, just to test an aircond or refrigerator, to check how accurate this little device can measures

Set everything to auto la. Easy.

Good info.

Cheers!~

The longer to monitor, the more accurate for the consumption.
