Excellent detailed review, should have read it before I bought a Daikin unit last week.
1 point where I'm concerned about sharp is that it can operate at max temp of 46C
daikin or general can operate at much higher temp....
It has been over a week since you were looking for an air conditioner. Have you reached to any concrete conclusion as to which type of air conditioner you need to buy? I mean Inverter or non-Inverter? Which models?
For the drawing room where the ac will not run much how will be a 3 star?

when is your next purchase of a washing machine and a refrigerator?I am not the kind of person who buys a consumer product because Mr. X has recommended buying product Y from manufacturer Z.
Guys I am thinking of getting a Daikin 1 ton inverter for my room sized 12ft x 12ft. I know some people might say that I should opt for a 1.5ton instead but here are my reasons for going 1 ton:
1. the room is on 1st floor and is surrounded by rooms on all sides, top included. So no direct sunlight. Marble flooring too! (Living in Ludhiana.)
2. I have found out the optimum tonnage for the room should be about 1.1 ton. However, the 1ton can overwork itself upto 1.2tons initially to cool faster, hence overcoming the problem.
3. Mostly night usage! Occasionally day usage.
4. Normal power consumption of a 5star 1.5ton AC is about 1600W while for the one ton is just 950 watts. Even with 50:50 ratio of on-off cycle, the average power consumption for 1.5 ton will average out to be near 800w. The 1 ton one might consume additional power at first but when temperature will stabilize, it'll end up using almost same or maybe even less power. Hence there is no justification to spending 12k extra on 1.5ton invertor AC.
What do you say guys? Any critique of the points mentioned or any personal experience which might be helpful to me?
For a 144 sqft room with marble flooring on 1st floor, having no direct sunlight, surrounded by rooms on all sides top included a 1.1 Ton Inverter like the Sharp AH-XP13LV will do the job just fine. Actually it could have easily cooled even if your room was as big as 160 sqft.
Opting for a 1.5 Ton Inverter will be a waste of money.
Can't go for that one because I have the regular copper tubes already installed inside the walls. So R410A based AC are out of question. That's why I am thinking about the Daikin one.
Havn't inquired yet locally but frm what i've read online, it's about 30-32k.
Moreover I have found out that the max cooling capacity of both Sharp one and Daikin one (by overworking the compressor) is 4 kW! That means the max capacity is same for both even though the default one is higher in sharp.
Does that include free installation kit?
Well I believe you are talking about the AH-XP13NRV (NRV series) while I was taking about Sharp AH-XP13LV (LV Series). While both AH-X12NEV (NEV series) and AH-XP13NRV (NRV series) use identical indoor units a year before Sharp used to offer a real 1.1 Ton inverter by the model AH-XP13LV (LV series). Comparing the specs I found this older model to be superior in every other way than the recent AH-XP13NRV.

It seems the LV model have a upper hand in every single department in terms of cooling capacity to NRV model at minimum, rated and maximum cooling capacities. The LV will provide a slightly more powerful cooling under rated condition while maxing out to a 1.2 Ton. The NRV can do a max of 1.14 Ton. The LV model also wins in having an even lower minimum cooling capacity ceiling of 0.23 Ton thus consuming slightly less energy when the set temperature is achieved while the NRV can do the best of 0.26 Ton. The LV model ODU is 500 grams heavier than the NRV, which may denote a bigger and higher capacity compressor along with bigger condenser.
And even though the LV is more powerful than NRV, it consumes less energy reflected in higher cooling performance having an EER of 3.63 while the NRV can do a best of EER of 3.13. Other than looks of NRV mimicking the MV series which is without a hint of doubt the sexiest looking air conditioner in town, the LV model is in a win-win situation.
Now let me stress there is a common belief that Inverter air conditioners remain always operational while switched on. While this is true to a certain point in that their compressors remain operational for about 98% of the duty cycle, for the rest 2% the compressor turns off just like non-Inverters. Say when the LV model attains its set temperature and tries to maintain it by coming down from its maximum cooling capacity of 1.2 Ton to 0.23 Ton there comes a point of time when even the 0.23 Ton becomes too powerful to maintain the set temperature and hence turned off. When the indoor temperature sensors of the IDU sense a tiny rise of 0.5 C, the micro-computer module again turns on to 0.23 Ton cooling capacity thus saving energy while a non-Inverter on the other hand turns on to a 1 Ton thus gulping more energy.
If we consider both LV and NRV above models as non-Inverter running at its rated cooling capacity always, then comparing the above two we find for every hour of operation the Sharp model saves 1150 - 1010 = 140 watts of energy consumption. This means 140/1000 = 0.14 energy unit saved per hour. For a 12 hour operation on a daily basis saves 0.14 X 12 = 1.68 units. In a months time of this daily routine saves 1.68 X 30 = 50.4 units. Considering an average rate of rupees 5 per unit, equates to INR 252 savings per month and for 10 months of use a year equates to INR 2,520 savings per year. In an assumed 10 year life cycle the LV model saves a total of 2520 X 10 = INR 25.2K over the NRV model. With LVs and NRVs costing the same I find no point in opting for NRV series other than looks.
Fortunately after recently visiting a electronic store here the good news is Sharp India are again importing their older LV series due to better performance capabilities over NRV series and are now readily available. I also saw the LV series on their display, price being identical to NRV series.

Hope it helps.
The more I read your posts, the more I believe that you are appointed by sharp itself! I already told you that the piping is different, so no R410A. The explanation and comparision was no necessary.. but thanks anyway!
Excellent detailed review, should have read it before I bought a Daikin unit last week.
