Orient invertech series air conditioner

[alitayyab]

Dear Ali, Very impressive calculations, unfortunately one point is missing (by me) that it consumed 10 units per day, which means 20 units in two days. Due to which if we apply your math on this we got 140-125 = 15 Rupees, %diff ~ 11%, in my view this saving % may increase due to the fact that i have noticed some hot air problems in my room, which may cause this extra consumption of electricity. I will seal my room and will check its consumption once again. can you check this pic of outer's sticker if this can tell us some more technical information.

Unfortunately I can't see the picture in your post (maybe attache it again?).
These Inverter based work best when they work continuously without interruption.
The operation of a non-inverter based AC is as follows:

Start ----> Compressor Starts (peak load) ----> Compressor working (average load) ----> Compressor Cuts out (Room at set temperature, nominal load) ----> Compressor starts (to reach set temperature, average load).

For an inverter AC

Start ---> Compressor Starts (peak load) ---> Compressor working (average load) ---> Room approaching set temperature (Compressor slows down, lower load) ----> Compressor stops (room at set temperature, nominal load) --->Compressor starts (to reach set temperature, lower load)

The steps in bold is what differentiates a inverter compressor from a non-inverter compressor. The former can slow itself down when it not required to work at full speed, while the latter is just on or off no matter how much cooling is required. If you have interruptions in electricity it would break the cycle and probably make the inverter AC behave like a non-inverter unit in the sense it will have to start over again.

Also not all inverter compressor are built the same. You will need to find out the exact make and model to figure out what's what. Also I would never trust the consumption label on a Chinese manufactured unit, not because they are Chinese made, but they are Chinese branded and they are capable of doing all sorts of tom foolery to make people buy their products. I was in China last year and visited 3 provinces and no matter where i was Gree were the worst performers. In fact most of their places meant for international conferences don't even have gree as their cooling solutions. No idea how it got so popular here. Maybe the commission to store owners per unit is significantly higher than others.

If I were in the market for a inverter unit, I would look at ACson, LG, Sammys, Pannys and hitachi. Get their model numbers and do some research.

Dear Ali, completely agreed with your comments and below formula for Inverar based A/C. Let me check for some more days and will decide if i shall spend this season with Orient or No.

Also very much agree about GREE, I visited china after 3 or 4 months and never saw Gree as there preferred A/C. Even in hotels or big convention centers, there cooling solutions are totally different. Somewhere i saw, TCL, changhong, than Haier.

will keep you posted

So what brand of AC did you see in China

Better Chinese brands mostly Haier in eateries in multinationals you mostly see Korean or Japanese brands, in malls it is Japanese units like hitachi, mitsubishis etc. The hotel where we stayed had Gree (in Changsha) and it was really bad. We were lucky to have good weather otherwise we'd have to ditch the place.

The general trend i saw in China; where you expect people with big bucks to shop = better fittings/ appearance. Other places not. There are tons of Gree units installed in China, and I am sure they must work for them to be selling so many. I am just not sure about the validity of their claims (in adverts or product specs). Better Chinese brands are competitive but are relatively more expensive.

The only products i saw in China that is cheap but works as advertised were/are the Xiaomi products. THe Mi4 at about 30,000 has the same specs as the much more expensive S5 (and better skinned android experience). Ditto for their other products.

Also, one might not know it outside of China but many different brands are owned by the same parent e.g. Oppo, Vivo and one+one are all owned by BBK. Thus you dont see any 1p1 being advertised in China, only Oppo and Vivo. Vivo is targetted at a younger audience with money to burn etc

ansari bahi pls share howz ur experience with orient inverter 1 ton? as i am going to install one soon

[alirazapw]

Boss I bought 1ton gree inverter ac.. Can please guide me how to adjust left and right swing ??? There is a button name as "Swing" but only Verticle (up and down) swing move upon pressing it... How to adjust horizontal swing (right and left)?

Thts manual. You will have to adjust tht by hand. Go close to the grill you will see adjustable knobs.

wasf bhai

Aoa

will you recommend gree. i have just sold out my dawlance (wasnt impressed with the air flow) plus i want to try inverter series.....

would you recommend gree or some other brand

i searched panasonic myself but reviews are not good.....its expensive as well.....

[msaad2]

dear all i am also planning to buy inverter ac as heard a lot about it ! please guide me which one is the best considering i have to install it on 1st floor

[msalimsabir]

greeeeeeee

[msaad2]

You really narrowed it down ! Are you using gree? If yes than please tell me your experience

[msalimsabir]

bro its really good ac. good cooling, nice amperage. i have 1.5 tons inverter, it starts from 1.5 goes max 8 then drops to around 2 when set temperature is achieved. i have experienced around 40% drop in energy consumption compared to normal ac.

[ashaina]

last week i bought haier 1.5 inverter.it starts from 1 amp and max go to 7amp for 2 or 3 mins then remain between 4-5amp until achieve set temp then it workes on 2 amps.haier uses mitsubishi compressor in 1.5ton inverter model and toshiba in its 1 ton inverter.
my room size is 13*16 with no sun light on walls but direcet sun light on roof which is insulated with 2 inch jumbolan.
so far i m very much satisfied with this inverter technology.

[shahbaz.ahmed2]

even these days i'm seeing Gree outter alot in Old Dubai but majority I'm noticing general, and carrier but still fair amount of gree as well. Which shows they can do fine cooling in harsh weather condition.

Here is my haier 1.5 inverter ac.

Nice! What is that device show digits in red???

Amp Meter.

[tyrone_40]

Amp Meter.

Nice would u mind sharing details and what is the cost? Does it show the actual amps being used or the total for a certain period?

It shows the actual amps being used u can get it from any electric store for Rs 200~400.

That's great. At least you can see for instance how much amps your AC uses for a certain period. Thanks
