This is the second part of the interaction with AC wallahs from last week. Last week when the Atom lost it's buzz for the second time I considered replacing it. Actually I should say re-considered as this project of replacing two of the splits with inverter hot & cold machines was initiated last year when I was getting the house painted. However at that time the non availability of stocks across NCR put paid to those plans. I pm-ed Aroy in my search for a good dealer and especially for getting a quick response (height of the busy season et all) and sure enough the reference elicited a promise from the dealer that someone would definitely visit me by the end of the day. Sure enough around 1830 hrs. the Daikin authorized dealer's installer was at my place along with the literature for the latest offering in the inverter range. Thank you Aroy for your help in the matter, it has resulted in bringing my search for a reliable dealer located close to my residence to a fruitful end.
So here is the latest from the world of Daikin
Inverters are being offered with the following Gases
R22 Production of this gas will stop Globally this year or is it 2015
R410 Introduced in lieu of the above gas but was always considered a stop gap arrangement ( for more info please surf the web)
R32 This gas was introduced a few years ago as a proper replacement for R22 and has now been brought to India by Daikin. It is more easily compressible than than the R410 and Ozone/Environment friendly and is touted as the real deal for replacing the R22.
Here are some figures for the two gases taken from the Daikin brochure for their 1.5 ton inverter split machines running the R32 gas [cooling only] and the R410 [cooling only & cooling + heating (X)] machines
Gas R32 [FTKV50] versus R410 [FTK(X)S50]
Running current (Amp.) 6.7 versus 6.9
Power consumption (W) 1530 versus 1550
Capacity(Btu/h) 17700[5100~20500] versus 17100[5800~20500]
With the Atom back in action on the same day, I informed the dealership that I will be back for the new machines at the end of the summer season. The climate will be temperate as I am going to change the location of the IDU to comply with information given in the next para and that will involve cutting a new channel through brick work followed by patch up and repainting etc. Further by that time the cooling+heating models with the R32 gas would have been introduced, which I would prefer over the hot&cold machines with R410.
The important bit of information thing that came out of my interaction with the dealer's representative was that the minimum run of gas lines between the ODU & the IDU needs to be 4 meters. At first I thought he was trying to sell me extra length of Copper piping but he insisted that this is an advisory from Daikin ever since the high pressure 410 gas was introduced. The reason given for this is that at lower lengths the high velocity of the gas does not allow dissipation of the force to a level that can be safely contained by the system (this despite a heavier gauge being used for R410 & R32) and over a period of time this results in premature failures especially leakages. In my install the total piping length is 1.5 meters, so they would simply leave 2.5 mts of piping coiled behind the ODU clamped to the wall. On further prodding he said that this is rarely advised by most dealers as the customers get the impression of being taken for a ride what with Copper piping costing Rs650 a meter. I cannot blame the dealers as that was my first impression too. Maybe members here who have machines with the R410 gas could check their installs and share whether they have that much length of piping between the two units.
So this is it folks. A week of discovering a dealer and a repairman both of whom are technically sound and more importantly stick to the timelines as per plan.
sukhoi, on one hand you say that you have not owned an airconditioner before and the you go on to comment on the quality of machines from the brand General.
Is your statement based on comments of dealers of machines from different brands and in fact including General, simply hearsay or from the web. Do elaborate as to the source and also in comparison to what other machines /other parameters has the quality gone down. It will help in updating information here vis a vis the current market dynamics.

(General was also considered but seems that it's quality has gone down). |
