Need help with AC power consumption

Inverter AC’s will be more power saving than 5 start AC’s. In some cases, Inverter’s can be 40-50% more energy efficient than their 5 star counterparts.

You can go through the below link to understand how Inverter AC works :

Only suggestion i have is to stick to Daikin or Sharp when it comes to inverter tech. Both Daikin and Sharp’s have been selling Inverter AC’s for a while in India and their performance has been undisputed.

An inverter airconditioner would consume (1 tonnage) 0.4-1 Unit per hour. If it’s used it for long hrs. i.e 8-10 hrs a day. It would consume an average of 0.5 units per hour.

If you don’t care about paytm cashback. Try to get sharp inverter airconditioner for the local dealer. It’s the best budget inverter airconditioner available in the market

There are 2 units here, indoor unit and outdoor unit.
So does each unit consume 990 W or is the total consumption 990 W.
Sorry for being nooby here.

Amey dear friend, would not go so far as labelling noob etcetera, but it sure could be that you are child-like (baal swaroop) . If the blower would draw the same energy to run, as the compressor unit, then it is doubtful if even topmost rich folks would take it.

The energy consumption of this Panasonic Inverter Split AC is 990 W.

So how does this work for a Split AC.

Is it the total power consumption = Indoor unit + Outdoor unit ?

I am new at this. I want to buy a good Inverter AC for 9-10 hr everyday usage for 8-9 months a year.

Will a 5-star Window AC be money-saving for me ?

initially I thought someone would point you to links or themselves make some brief of energy versus power consumption.

dna_uncut did make some really valid points and has got close approximations in the calculations.

I am not sure if it would overload or help you decipher, but you can give a try to > http://www.frequencycast.co.uk/howmanywatt...ml (and then http://www.think-energy.net/KWvsK...tm or http://www.energylens.com/articles/kw-a...wh)

do not take it otherwise, at the on-set I can not resist the urge to ask something.

If I am new to something or want to get to the bottom of things, I’m usually restless to reach out to all relevant people or resources.

With that background I ask,
did you make any general or specific efforts to bring some clarity? (assuming people mostly are proficient at normal internet use).

Or tried to talk to any brand’s own service centre people to know details (assuming the need/demand for you didn’t spring up overnight). Many of the service dept. folks too can be reached via the call collect (1800) numbers so it is free to us.

Ans. 1] energy consumption is final number for using that gadget as a whole.

Ans. 2] Yes. and NO.

your needs are pretty much.. showroom or office like requirement.

I wouldn’t force, but highly recommend to mentally junk all ratings and abbreviations except universal ones and go by quantifiable terms or on pure merit.

BTU and not just kW is what matters. British Thermal Units 12500 theoratically is 1tonne. But most brands do miss-selling of a 11000 or 10500BTU being called XYZ2015_new1T (model name), thus giving an impression that it has tonnage value 1.

the 5star rating given by Indian agencies may not be 5star in Saudi or vice versa.

ANS. 3] The pay-back in your case (use of 10-12 hours for 3/4th of an year) would easily justify higher upfront costs. (of an Inverter unit over a normal unit). Inverter products (any white goods) aren’t certified like normal goods.

Perhaps you can build on dna_uncut’s ball-park calculations and check with actual use data, to find out. Mostly the lower power utility bills recover the higher upfront outgo in 3-4 years at max.

do make it a point to use any Inverter aircon with an appropriate capacity stabilizer which supports wide range, NO MATTER WHAT the marketing literature or person says. [with the kind of power generation and transmission we get in India, 5000rs of a Stabiliser isn’t unwise compared to the hassles of a non working unit! And once paid service and out of warranty, any PCB replacement would mean lots time and money. [it can roast in rare case of spike when power suddenly comes and isn’t in desired range.]

Some things that you can revisit:

§] is the area/premises to be cooled under 120 sq. feet carpet and not over 9feet ceiling? [12500 BTU would barely be efficient. Anything bigger and you need to think of at least 14000-15000BTU]

§] are you/buyer really interested in this on-line thing? (not to proud to share it, but cash billing is cheaper. Neither dealer, nor buyer shows it in their tax file.) but if you buying it to a business, ALWAYS charge it to Balance-Sheet and even take depreciation benefit.

§] panasonic (or others) are habituated to change few design elements and every year pky becomes sky or whatever. Price goes up phenominally. Rather buy a 2013 or 2014 model of any brand. Don’t fall for gimmicks like this filter, that ion technology or newANDimproved.

§] Matsushita (now Panasonic) are really serious for retail push now. But do check how good or otherwise is local support? Is it franchisee or brands own centre?

§] most brands if using copper coiling have similar efficiecy, still ask for power factor [PF]. Yes Sharp is to white goods, what Jaguar is to lux cars (the VFM product for poorer of the rich guys)

Sharp products are result of good R&D and build quality, but again it boils down to prompt support.

Pricewise Bluestar, Voltas would be competitive.

Productwise, your choice is okay (though panasonic has better cheaper models), Daikin, Sharp, OG are good. Hitachi, Mitsubishi are better (and priced accordingly).

Rather than the upkeep and removal at servicing of window unit, split is hassle free.

it’d really help you if you research what a Cube Aircon is and why Panasonic exclusively launched that type in the price sensitive but hot weather market as India.

Total … Power consumption is calculated based on compressor capacity (1 tonne, 1.5 tonne etc). A one tonne aircondtioner would consume 1 unit of current an hour on an average (1.5 U incase of 1.5 tonnage airconditioner), irrespective of star ratings, star ratings is just a marketing gimmick. But an inverter airconditioner differs from this tech and if used for long hours without interruption it would save 40-50% of power consumption when compared to conventional star rated airconditioners.

i too agree on this! And it is amazing that invertor refridgerator or an aircon, never shut the compressor down. I was too un-informed as to why 30-40% less consumption. And one of the answers was, that every time any machine (or automobile or even a jumbo jet) has to power ON it draws on unusually high power. It also ‘wastes’ it at time of cut-out/ shut-down.

So inverter tech has ‘done away’ for the compressor to be booted everytime. So no sudden thud or vibration at cut-out of temparature. It will simply slow down BUT remain on.

@dna_uncut in the propah ‘test and certifications’ sense all ‘ideal’ scenario ratings matter. Be it water purification or crash test strength of cars/ aeroplanes or cooling rating of an appliance.

The pathetic fact is, no laws for bad advertising or against imagined claims exist.

It is a known fact that the ‘ideal lab condition’ would have exact ‘N’ cubic feet space, outside temp. under 30 and no humans or warm things or doors opening as in real world.

About marketing, Tent Purifiers and Parle Biscuits P Limited would have to pay through the nose for falsification and unsubstantiated claims if this was Europe.

While that retired mare Hema says: tent deta hai duniya ka ‘sabse’ shudh pani, EU would say prove it or beep beep beep.

And those Doggy treats Parle-G would never be allow to claim itself a milk biscuit or show pictures of milk on pack. [those things have hardly 0.6gm milk powder in 100gm biscuit. That too, skimmed milk’s solids]

yup, ignore marketing gimmick!

Really appreciate your effort, the links were informative too.
I am kinda more confused now.
I wanted to go for an Inverter AC, but now I think 5 star would be okay too.
Will visit the stores this weekend. Thanks for your help. KG

Thanks for the kind words mate!

for the usage pattern you charted out, no! Inverter AC will payback the cost difference within few years.

Yes please do visit a few dealers. And pray you get guidance instead of sales talk.

You seem to be caught in the ratings loop. Amey think of it like that, how often do vehicles give rated/claimed mileage in regular use? Or the speed touches the max on the odometer?

Save way, ratings under test conditions are pointless.

Some things I’d prefer not to say in open, but keep in one on one. But let me share, that the most recent (2015 season) purchase was of 3 Daikins, 2 of which are the Daikin inverter FTKE35GV1 .

I couldn’t get them to buy Panasonic as it wasn’t easily sourced. But the Daikin dealer shrewdly took cash payment and.. Well its embarassing so wont say much, but with installation tidbit costs it came to 36000 i think.

edit:

at this hour and away from that location, I could not dig up correct documemts but I am pretty sure it was slightly above 37000INR including the paraphernalia of a stabiliser and partial ducting and installation.

Please excuse the old shabby look prior to the interiors getting done. Image was taken barely hours after the final touches of repair/ masonry work was done, by some simple or inadequate camera.

Daikin FTKE35GV1 Inverter aircon

though I’d still remind you Amey to do some looking around at what Panasonic Cube Aircon is. Not that I have any personal stake in its uptake, but depending on your space constraints, it can be a very value buy. Youtube does have a few uploads about hands on run down from 1 or 2 users nee buyers of the Cube and has coverdd tips for both OD unit and the blower.

bookmarked!
