Forerunner
i have a small room and need ac. i dont need ultra low cooling or something.
since i have a window i guess split not needed !
just need pleasent temp as i dnt like to use planket and simulate winters.
ac will run only in night from 10-8 in gurgaon .
it really dont care if it takes 25 mins to cool room than 5 mins of those big rated ac's
im thinking 1 ton and brand voltas , hitachi or daikin . is invertor tech. worth it for me ? will it pay off ? ac will run from may to end of summers every year . having lived in fans n coolers , ac i have less knowledge of . please guide me .

 
Buy only inverter AC.. it will be very cost effective in long term.. recently I too have purchased AC I thought non-inverter is perfect for me as won't need to run for long hours. but as we work from home. the AC is on almost all the time in summers. thus resulting in upto 1100 units consumption per month. on 5 star rated 1.5ton ogeneral. with 750% increase in my electricity bill :(

you can go for Panasonic CS-YS12NKY 1Ton inverter AC for about 34k
 
^ 1100 units? Wow. In 4-5 months you could buy a new AC with the amount spent on electric bill's I guess.

Invertor AC try to maintain room temperature as close as to set point by continue operating compressor .when we start ac first compressor will rotate at full speed to reduce temp. to as close to set point,as room temp. Reach set point compressor reduce it's speed to only maintain temp..and in normal AC compressor rotate on full speed in starting but when temp. Reach set value it completely shut compressor off...so compressor will on- off according to temp. In normal AC where in invertor AC compressor will run as low speed as possible after achieving set value temp...
So inverter A.C will save some unit if any one planning to continue run their A.C..

Inverter runs all the time at low power to maintain cooling. Non inverter will stop and start after some pre determined time intervals and hence it will consume more power while doing this. I'm guessing the cost savings come from doing away with the cooling/heating cycle of refrigerant in tubes. If you stop an AC for some time after cooling the room, the refrigerant will come to normal temp after some time. In inverter since its in constant circulation, you will require less energy to cool it further than say from similar refrigerant at room temp. This is my theory. Don't know how much of it is true. :x :cool:

so will invertor tech. ac help only those who keep acs on for 12-14 hours + ?? i will use ac fr 9 hours max everyday .

It will save you money if you keep ac on for 8 hour or 12 hour,people recommended inverter ac to whom who can keep ac on maximum hour so they can have their extra money back in short which they paid more over normal A.C..

Also how much extra are inverter acs over normal ones?

It's more than 10k give or take...

And for how many days/months? Is the AC going to be operated only during summers or throughtout the year? The ROI of inverter based ACs largely depend on the usage pattern. If you are buying a unit only to be operated during summers and for a short duration such as 8 hours, it may be a good idea to get a regular AC with a 4 or 5 star rating instead. If you buy an inverter based model, we are talking of at least 35k for a 1.1 ton unit - Sharp ad I had noticed in the newspaper yesterday.
 
IMO, an inverter AC will start saving power from the start, whether you're running it for an hour or 10 hours. Example: if you run a normal AC for an hour, it will start and stop at least twice in this time period. Say it takes 3 units every time it runs on full power. It will take 6 units in this hour. Inverter will take 3 units first at start, then since it keeps running on low speed of less than a kw, it will take less than 3 units in the remaining time. Suppose it takes 2 only. You still save a unit an hour. That's about 240 units a month if you run it for 8 hours a day.
 
this seems complicated . i think we need to calculate how long invertor ac will need to be run to cover the extra initial investment based on power tarrif and usage . anyone smart enough to try can post to help us all . i think my usage is low so an normal 3-5 star will do fine .
 
You will keep using the AC for quite a long time(10 years maybe). By that time, I think you will have saved quite a lot of electricity when compared to a 5 star split AC.

By the way, the BEE ratings keep getting updated every year. So a split AC which is 5 star this year, will be just above the 4 star rating next year and so on. On the other hand, the inverters are so energy efficient that they meet the BEE 5 star ratings for the year 2016(the detailed calculation were provided by @RishiGuru in another thread).

yes the usage/cost difference with inverter AC is just to justify the cost difference of inverter AC. inverter AC save power even when they have limited usage. I was unlucky enough that I estimated my usage incorrectly :( my non-inverter Ac cost more than some good sharp inverter AC. though its still less than fujitsu inverter AC

does running ac at 25 degrees take quite less power than at 18degress ??

yes, the cutoff time for the compressor is less. and thus it doesn't have to work harder to attain 18 degrees. although in both cases it would consume almost the same power when the compressor is running. its just that compressor is running for shorter time vs longer.
