i dont think people will pay high for the inverter piping and use it for non inverter series aircond. if there is, it is only a small group of customers (price doesnt matter) would do so.

For conceal, is good to have inverter for future usage, better pay extra few hundred, than later need to hack and redo.

Want to ask about the air con setup for 20x70 living and dining hall.
Usually how is the setup?

2hp in living and 1.5hp in dining enough?
Or 1 2.5hp in living only? but can dining get the cool air?

I need some advice here. Appreciate anyone can share their current setup.
Thanks.

20x70 living and dinning hall is very big, you need lots of A/C

Sorry, let me do some correction. The 20x70 is the size for the entire house.
The built up area for living and dining area is 20x26 (including staircase) and dry kitchen area is 9x6

How should I place my air cons?

It will also depends on what is the temperature you are expecting form the AC. You have a staircase, which I presume is open to the upper floor. Thus source for cold air to escape. Unless your living & dining areas are enclosed, it will be difficult to achieve a very low temp.

Thanks for replying, normally i set the temp to 23 or 24 degrees C. Since this is my 1st landed DSL House, therefore i would like to know from other forummer what is the usually placement for air con in ground floor and what is the needed horse power.

Thanks again.

For my case, I place the both the AC units at both ends of the living & dining.

thanks, thats the good idea !

I use 2hp for my living hall, 1hp for dining area (with dry kitchen).

My living hall is about 21 x 16, dining area 11x 20

For me is not really cold, just enough to make it only. If I have the cash, I'll go for 3 x 2hp.

wei kee your dry kc and dining area is together? so living hall and dining area is seperated?

maybe all brand inverter aircond can use non-inverter copper pipe in future due to advance technology coming that time, all aircond manufacturers consider this market in future as no need for consumers change thier exist copper pipe. just to my cent...

hmm... i cant afford 3 x 2HP too, dont forget the electricity bill

Here is my floor plan, smaller than yours, hope 2HP in Living and 1HP in Dry kitchen is sufficient.

Living hall and dry kitchen are together. Dinning area is in between living all and dry kitchen, all open area.

Maybe Malaysia will adopt this too. So copper can be standard like R22

Added on November 16, 2011, 10:18 amLiving hall 2hp, and dining area 1hp should give you some cooling, if you really like cold like i do, is really not enough. I like minimal 20c

wa, 20c pretty cold for me d

My style, if want cold make it cold. not "5354". I can stand cold or hot but not stuffy.

philipcs, dry kc also got aircond?

The Dry kitchen is together with Dining, so is for both. Then 2HP for living loh, hope this work

Wow.. so many airconds.
Philip, total 4 units 1HP and 1unit 2HP for your house?

I guess most with have or similar design floor plan like above, hence just want in place there.

I plan to (already purchased) place 2.5HP (Living) + 1.5HP (Dinner area), as I didn't see that will possiable make my area cool except if I inplace door at stracase and entry before the Kitchen area...
