Before buying, the shopkeeper said it doesn't need a stabiliser . After buying, he said, we don't need one if power quality is fine. So do we ? What's the criteria ? Thanks. |
Congratulations anku94, The criteria for buying a transformer is in bold above. The electronic control panel equipped Estrella boasts of voltage protection feature and not the one with mechanical controls. However for both the specified voltage range is 230+/-10%. If I understand it correctly beyond this range in either direction the voltage protection feature may turn the air con off or maybe just the compressor for a few minutes (CAUTION Could be entirely different from my explanation) If it is so then it would be a bother as the Northern grid is infamous for frequent brown outs in peak summers. I believe a suitable transformer would be a prudent safeguard. The dealer may give you a package deal. Quote:

The ideal size for your room is 2.75 tons assuming that the ceiling is 10 ft in height and is not exposed to the elements. If I factor in the various doors and windows then the required tonnage jumps to 3.3 tons. That is the theory. In reality though you may be well of with the 2.0 if you are not looking to achieve 21degrees Celsius. If I knew the room usage it would be better. By the way my house in Delhi has a central lobby which doubles up as the dining room/ Tv room and has half a dozen doors apart from the largish living room also opening into it and at 20x13x10 feet it trundles along with a 1.5 ton OGeneral machine. It does not chill but we are comfortable even during afternoons of peak summer. Of course when guests come over the 2.0 tonner in the living room and a strategically installed 1.5 tonner window unit with a super throw blower also come in to play to counter the ambient temp + kitchen heat + frequent opening of doors etc. Quote:
1. In 2.0 range the prices go from 30K for Onida to 56K for a Mitsubishi. Are Mitsubishi,Daikin and General really that great? We have a General at home which is running great but is the premium worth it?
| YES Quote:
2. Mitsubishi has two companies within itself. One is Mitsubishi electricals and one is Mitsubishi Heavy industries. Are both known for their excellent quality? Do both have a proper sales and service network in India? we have been quoted 50-52K for a/cs from both Mitsubishi companies and 49K for general.

A few posts ago a member reported using the Mitsu Heavy air cons and in his opinion these are better than the plain Mitsu Electricals. My experience is limited to a single unit of Mr slim series of Mitsu electric for a 1.0 ton unit and I found it to be good too. I will recommend that you look at the Btu ratings of the two units and go for the one with the stronger compressor, the price difference is not much in any case. Quote:
3. Only a few models from General and Hitachi have 5 star ratings. Does this really affect electricity much? or are we well of going with a 4-star and 3-star model.

In the 2.0 ton and above range look at the comfort level first. Even the 5 star rated ones are not going to be very frugal for these loads. Also if you look at the compressors of those with the higher star ratings they would be rated at from 20000 Btu to 23000 Btu.
The 2.0 ton from OGeneral is a particularly efficient machine with a 25300 Btu compressor and it has a fantastic EER of 10.54. Quote:
4. Videocon has a 2.0 ton split (some VIS model) with 5 star rating going for 50+. Have they gone mad or does it have some new technology?
We are currently set on Voltas gold 2.0 for 35K with install because it is the only 4-star a/c in the low range and because we have had two voltas a/c's which have last us for 10 years (one is still working) but can look at MItsubishi and General if they are worth the price over the period.

Stick to the Japanese machines especially OGeneral for the 2.0 ton and you can include Daikin your scheme of things only if you decide to go with the the 2.75 ton machine.
