Split ac or wall mounted fan??

Well i know alot of helpfull thread already exist but by questison is as already summer heat has started in mumbai...so was thinking to install wall mounted fans since i guess ac consume lot electricity....is it true for split too???Alot of ads i see with eer ratings and all...so it looks they consume less electricity is it true or i can go with my other idea...since the place where i want to install is ard comp desk so direct point ard seating needs air.....

Any suggestion or post are most wc
 
comparing fans with acs is like comparing potatoes with oranges. and no matter what the EER is, your power bill will go up with an aircon, however with a judicial and right selection and use, it wont go up a whole lot.
 
what my practical usage has revealed that fans at their full / high speeds are also high energy hogs.

if used judiciously in combination AC and fans will not bloat your electricity bills a lot.

and if you are planning two fans in conjunction then you are not going to save much in electricity and to add you will have a lot of noise in the ambience.

if you can afford the initial cost and little rise in powerbills ACs are the way to go.
 
bfore u head to check consumption ratings...u shud select the tonnage of ur ac acc to room...for most cases a 1.5T is app...many times ppl get mislead by the lower consumption rating of a 1t ac...but the thing is a Iton ac will take longer to cool a room compared to a 1.5t..so in da end a lower tonnage and lower rated ac will cost more in terms of electrical units....

wrt to ac types ...dont know abt the latest split ones but ive always preffered the window acs for their easy servicing...
 
If you have conformed to go for AC then split AC is always better... than window AC........

But if you are only feed up due to summer then Air Cooler will be best option...
 
Budget is not a problem i do have a 1.5 ton ac...but its just that its on only in summer...we dont touch it rest of year..so every time maintenance stuff gets added....also when ac is in used monthly bill goes twice.....thats the reason i asked abt wall mounted fan.....for split i can go till 20k one ac stuff.....but it should be economical low maintenance stuff

Cooler may not server well in coastal areas like Mumbai.

Correct. A cooler cannot help much in any place with high humidity.

Can't comment abt split and window a/c though ..

hehehe trying to make my own.. solar powered.. been working on/off on a similar project since the last 2-3 years and if you are really adventurous check out the technology on gas refrigerators and you can try experimenting a little to adapt it to a solar a/c :eek:hyeah: (Stautory warning: Ammonia refrigeration is a risky job and ammonia is a very corrosive substance.. )

just my $0.02 :hap2:

For those of you who are just as fed up with the heat (or the erratic power supply as in my area) as I, you could look at alternate technologies.. wind solar etc..

It would be helpful if u post some links where one can start looking at alternate tech relevant to India.

Power is so erratic in my place, I run a genset almost 4 to 5 hrs daily.
 
Heat Engine Projects <<< lots of stuff, very messy site but also has the most links.. with lots of links with info and technology. Check this out if you haev the tech know-how or the ability/enthusiasm to sift thru all that and do something on your own :D

Home Power Magazine: Solar | Wind | Water | Design | Build << site with lots of info and helpful facts, DIY projects etc.. if you are good at using google/t*rrentscan you might get to some ::ahem:: t*rrent links with a collection of their mags to er.. download. lots of DIY projects for the enthusiast.

Wind Power Generators -- Windmills <<< lots of stuff here.. again DIY stuff

WhisperGenTM heat and power systems <<< this is a commercial site for generators made from the technology i referred to earlier. check out the videos. I am trying to make a similar kind of engine although not of the same kind. Alas!! Three prototypes and a substantial payout later I am still not very close to getting it perfect. Hopefully, this year I will havemroe time on my hands to work on this (Building my house this year, which will incorporate a lot of this alternate energy stuff and will probably have the stirling sort of generator to augment the regular power supply)

However, "relevant to india tech" does not mean a thing unless you mean availability of the stuff required to do all these DIY projects. The technology does not change. you can apply the tech in any place. (unless you are talking of some geothermal solution- power from earth heat - like in australia or wind power which depends on location though)

yes, some of this stuff is expensive to build. But trust me brother, if you have lived in my area you will wish you could strangle the people who supply power to our houses. Which is what got me started off on this a while ago. (Funny thing is, I was also a consultant to the local power supply company - software architecture and accounting/management packages .. ironical !!!)

If you need any more info on this stuff you can always mail me at ktejaswi.AT.yahoo.co.uk

have fun...

In terms of power consumption over the lifetime of the unit...defnitely!

The question really is pay little more upfront for a split with savings in the long term vs pay less for a windows ac and higher costs later on in power as a window ac is not as efficient as a split unit.

As to which unit to get you will have to make a list and look at their power consumption and then calculate savings with info in this thread.

The other disadvantage of course is noise, splits are quieter :)

i'm not aware of how good the current windows units are, its possible they might have become more efficient but only the figures can prove this.

Its very important to get the sizing done correctly. Blue Star has a handy tool to just that.

Regarding whether a bigger unit is better in terms of efficiency, i am not sure about it anymore.

Also consider a bigger one will have more startup-spin down cycles that puts stress on the compressor. Whereas one of the right size wil be moving constantly. And its gets the max efficiency at running speed rather than at startup.

I am contradicting myself here from what i posted earlier, but did some figures with windows untis and found them to be pretty decent.

It really depends on the unit in question. I will shortly be putting together a list here of diff units and then hopefully it will be more clear.
