They always struck me a Thai brand - I'd never consider buying a new one when you have the likes of Panasonic, Samsung, Sharp, Mitsu, LG, Saijo Denki et al making good products.

The most important thing for me is not the brand but rather the service support . I never buy from large retail outlets like Lotus, Macro, Homepro or the like. Buy from them and the odds of getting satisfactory support if you have problems is close to zero. I buy from a local shop where I know the owner. May pay a bit more but if problems, a call to the shop gets quick helpful result.

Here in Roiet, the best aftersale service is provided by Mitsubishi. Aftersale service depends on who owns the "authorized" service center. Mitsubishi may not be the best in your area JJ. Best to talk with folks around you to find out their experience with aftersale support.

But still very much in the market. I see Daikin units on every commercial site I work on.

All our aircons are Saijo Denki
Only had one problem and that was a mouse eating the wiring in the control unit.
Had it repaired no problem but had to be sent to Bangers.
The units themselves have worked perfectly for nine years

those were the days!

things have moved on a bit

Don't know why you keep spewing crap on this forum,but Daikin is WORLDWIDE renowned as the No. 1 in airconditioners.Probable reason is because they are also the only company that specializes solely in refrigerant techniques and not like all the other company's produce from coffee machine to airconditioner and everything between.

Edit to add : [at] Marmite Daikin isn't a Thai brand,it is the biggest airconditioner manufacturer with origin Japan.

I know it isn't, but it always seemed to be marketed as one.

don't know why you keep spewing crap either

give us a link

they are not so well known as Panasonic et al by the HOME user
which is what is under discussion

in addition, they may be available worldwide, but they are made in Thailand (for the Thai market), that is what Marmite was referring to

so stop being so rude and get a grip

they are made in Thailand for home consumption

And where do you think that the panasonic,lg,samsung or any other brand are produced?
By the way daikin doesn't produce solely for the Thai market here in Thailand.

As for a link,look at this one and try to find panasonic

The expansion of Daikin's factory in Amata Nakorn industrial estate, Chon Buri, is for
exports to clients in Japan, Australia, and Europe. The company is planning to hire
668 more staff.

so what? you are avoiding the point

Daikin are not so well known in Thailand as many other brands; I was not really aware of them for the home market

My friendly aircon guy recommended them to me after me going to Siam plaza and looking at what was on offer

They are generally the most expensive and most customers wont pay the price.

Jandajoy go for a 15 or 16btu, a 12 will be struggling in the hot season in a large uninsulated room.

**escaped** · 08-04-2011, 08:33 PM

When you ask an aircon technician they will tell you to multiply the square meter with 600 to arrive at the needed Btu. 36 m² x 600 = 21.600 Btu

**EssEffBee** · 09-04-2011, 03:27 PM

Which is the obvious & perfect reason why one doesn't use 'their' method of determining a/c size.

**escaped** · 09-04-2011, 08:12 PM

^ Maybe you want to prevail the right method then?

strangely enough, the number of windows, the amount of power being used in the room and the location of the room, as well as its function are all factored into the calculation

Those factors need to be added to the m² x 600 rule of thumb.

Any technician will start with the idea of a normal room with 1 door and 1 window.When you build a glass box for sure other rules apply.

I don't think that makes sense

I think you mean would I like to post the best method of calculating the BThU needed?

Google it, plenty of sites with full explanation

aircon size calculator

mind you, they work it out using the square metres, not cubic metres, so if you have a very tall room you need to add a bit more

Actually my reply was pointed at EssEffBee instead of you but let's give it a go.
I'm not an native English,what you probably discovered already,so many times I use a word in the wrong context.
I know there are plenty of calculators on the web but I found that they mostly calculate using m³ instead of m² because in most country's the aircon also has a heating function therefore the height is important.In Thailand airconditioners have only cooling function and calculating m² is sufficient.

This is one calculator from whirlpool Australia http://whirlpool.net.au/wiki/aircon_faq and it also lists a buying guide as which brand is the best and why.

escaped, your concept of the sizing of airconditioners is severly flawed.

strangely enough, the number of windows, the amount of power being used in the room and the location of the room, as well as its function are all factored into the calculation.

I'd also like to add that the number of people frequenting the room be a part of the equation.

There is no way on earth that someone can multiply the square metres of a prospectiove a/c installation by 600 & arrive at an 'accurate' answer unless they are;

1] Thai.
2] Complete imbeciles.
3] In no way consider other heat creating factors.

You really need to learn about a/c before you announce such rubbish.

Excuse me Sir,but did you notice the 3 words highlighted in green in my previous post.They say " rule of thumb " and as far as I'm concerned that has a completely different meaning as " Accurate ".I also added that a technician would start from the idea of a room with 1 window and 1 door,hence the m² x 600 Calculation.Add more factors and the formula will change.
Now please point me to a post of mine where I say that m² x 600 is an accurate calculation.
The post of my calculation was more directed as to show that a 15-16000 Btu unit is way to small for a 36 m² sized room.You should start from at least 21000 Btu and then add all the factors like extra windows,south side facing,extra people in the room etc. to reach the correct size.

Maybe, maybe not. Here's what I have in concrete red brick wall, three meter high ceiling with ceiling insulation. All outside walls have foliage provide shade on walls 90% everyday.

Three air cons in house all doing a good job cooling the room.

8x8m (64sqm) = 15kbtu. Three large sliding glass windows and one large sliding glass patio door.

4x7m (28sqm) = 10kbtu. One large sliding glass window.

7x13 (91sqm) = 16kbtu. Three large sliding glass windows.

So you guys calculate your hearts out. This works for me.

Please, feel free to support your theory. It's not the first time a theory has failed in the history of the world.
