Split AC - Distance between Indoor & Outdoor Unit
- Thread starter Emperor
- Start date
it depends upon the room which is to be cooled.
what are the heat generator in that room
whether direct sunlight falls on any walls of room
where the outdoor unit will be placed, whether it will have to face direct sunlight or not?
But to be on safer side you have to keep the distance between indoor and outdoor units maximum 15-20 feets so that energy efficiency ratios do not change horribly, socondly if the piping is long make sure the vendor uses good quality and proper insulation so not to waste the compressed and cool energy.

You might want to consider EER when comparing units, enrgy costs are going to rise, if you pick an economical one, you end up paying more in the long run in power, pick a more efficient one, you pay more up front but save more over 10 yrs.

Get the voltas 1T vertis split! Best VFM + very efficient!

I looked at the voltas one, earlier, its quite powerful for the delhi summers, the calculations i made gave it a beter EER than say any of bluestars gear.
Tho they say its not required in a place like Bangalore, the more powerful the AC is the less it has to work to keep the place cool, hence more savings
Talking to the AC guys, and i was shocked when some of them did not even know what EER meant !!..not surprising since thats prolly one of their weaker selling points.
Ignore the sales bots, get the technical specs form the companies websites, if they don't have it demand them and work it out yourself. Actually EER of 11 is preferred, best is 13+ but i don't think you will get those units here.
The idea is if you get a unit with an EER of high 10 or 11, the unit will pay for itself in power savings over its lifetime ie 10 yrs.

Some of Onida model have EER 10.4 but don't know about Quality and what about VFM?
Split AC have only 10 yrs Life Time:S

10 yrs is the estimated lifetime of the compressor, if you want to replace that then you can get another 10, but given the way things are nowadays, ie selling cheaper stuff with lower quality to make newer stuff to sell for more profit. Gone are the days when things lasted 20 yrs.
I'm thinking they will say we dont make that kind of compressor anymore. So you will be forced to buy another unit in 10 years time.
Another brand you might consider is General, saw an ad form them recently, where surprise surprise, they mention high EER. Check the specs and if it works out, might be a good deal.
I got into EER some time back as a friend asked some help to outfit an office, so there were at least 3 units required. If you don't care about your long term costs, if getting the cost of the unit back after 10 yrs is not important, you can go with whatever unit is cheaper.
Another parameter you might consider is noise, a normal conversation is 50dB, so you want a unit thats at least 5dB lower.

@ stick : any AC to function well has a life span of about 10 years as corrosion from the humidity resorption is going to take its toll be it Split or Window.
EER is mentioned in any ACs literature go and check it.
IF you want for mumbai go for a rotary compressor as they are better in high humidity areas while reciprocating processors are better hot and dry areas.
so surat, mumbai are better off with rotary while delhi, jaipur, ahmedabad, banglore are better off with reciprocating ones.
I still repeat my suggestions : VFM brands : Onida, Electrolux, Frizair
High end brands : O-General, Daikin, Hitachi
Stay Away brands : Voltas, LG, Samsung.

I second medpal about his observations...
Onida is good but it's website gives conflicting specifications...
you download the AC brochure or take a printed one from Shop...the EER for onida 1.5 ton spplit Ac will vary from 10.4 to 10.18...
whereas if you see the product specs individually the EER is 10.6...quite amusing
I think nowadays Godrej is also making pretty nice AC's

I would recommend buying the Fujitsu General brand of ACs from personal experience for they are built with a very robust rotary compressor and also the internal copper piping and sheet metals used are of high quality.
EER(Energy Efficiency Ratio) is somewhere around the 9.3 mark for the 1.0 ton as mentioned on their site. Going by that it would consume about 1300 Watts (12000/9.3) for every 1ton of refrigeration. A bit more but it tends to cover a wider cooling area sq. feet(about 250-300sq feet) due to better swing circulation.
As for your questions, the outer piping between units can be at the most 25ft provided good felt insulation is provided.
Darker rooms will be cooled more easily so lesser power consumptions if u use at more at night than daytime.
Also since you live near the Creek corrosion problems may be more prominent so be ready for frequent gas chargings with any model.

I feel that inverter technology is useful in power savings only in western countries and not in tropical climates of india where the heat load is very high.. Infact if you go to a foreign site they will recommend a 1.5 ton ac for room sizes up to 500 sq ft which is not relevant for india... here compressor switches on/off every five minutes so not much use for controlling the compressor speed precisely

It's that switching on & off so frequently that draws the most current. So i'm not sure whether you can say its not applicable here. From what i understand with inverter tech, it prevents this by keeping the compressor running at lower speeds, so if it needs to cool more, it just speeds it up. The other side benefit is temperature stabilisation. So its not too cold or not cold enough at any point in time.bigbyte said:
The biggest problem is the cost, they are not priced competitively, there are much cheaper non-inverter units on the market in comparison to what they are asking for inverter tech ones, even after taking life time running costs into account.
The DC Inverter digitally controls the capacity supplied by the air conditioner, by modifying the electricity supply current frequency or intensity, to insure a smooth rotation speed or capacity of the compressor. This allows precise matching of the cooling capacities to the actual operating conditions. When the room temperature is set far from the set point (required temperature), the DC Hybrid Inverter operates at maximum capacity to ensure the set temperature is reached quickly.
But how much energy savings it will result I don't know. And though this thing looks good on paper, due to the large inertia of the room, how much conformance to set temperature is actually there is desired to be seen.
And you are absolutely correct that the biggest problem is cost, but I think once this technology is well proved no one will manufacture the non-inverter units and all you'll see is Inverter AC's. Just look at the case of Flat and Round tube Televisions.

it should cost somehwere around the 20k mark for a ton.
Mine was an import piece cost me somewhere around 12-13k(no warranties or anything but...
Nice to hear that important one is Resonable price, from how many years you are using it, can you give some detail specs about your AC and from where did you purchase it.
What you think while compare it with other brands?
