Links to compare Mitsubishi and Daiken A/c's

[pbassham]

I was recently shopping for air conditioners and found it hard to just find the energy specs compared between brands, but found a decent (not elegant per-se) way to do it.

Find the spec pages

(here are the current link examples for the mitsu-daiken range I was looking):

And then I just took quick screenshots of the column of the model I was interested in and pasted it in a numbers (excel) file and put the prices in a text box for easy viewing.

This significantly sped up my research, so I thought I'd share.

Its nothing special.

Here is a screenshot though. They aren't pretty because I lined up the screenshots by the EER #.)

Edit: I almost forgot the other big part. I found a spreadsheet that you plug in your info and it calculates the savings and such from Energystar in the states. It is also nothing fancy, and should be a website, but oh well, this works too

If you want to give them a run for their money, better include the Saijo Denki Hybrids...

Full specs with EER here: http://saijo-denki.co.th/res_hybrid.php

Reasonably good prices here: http://gaincool.com/index.php/th/%E0%B9%81%E0%B8%AD%E0%B8%A3%E0%B9%8C%E0%B8%9A%E0%B9%89%E0%B8%B2%E0%B8%99%E0%B8%97%E0%B8%B8%E0%B8%81%E0%B8%A3%E0%B8%B8%E0%B9%88%E0%B8%99/%E0%B9%81%E0%B8%AD%E0%B8%A3%E0%B9%8C%E0%B9%84%E0%B8%8B%E0%B9%82%E0%B8%88%E0%B9%80%E0%B8%94%E0%B8%99%E0%B8%81%E0%B8%B4.html

Well, I didn’t consider that brand because I don’t know anything about it, but especially when you compare that 36k BTU with the Mitsubishi that I ended up getting, it looks like it is 30-40% more efficient. That is quite a bit.

So, I may switch to that one if they will let me. The other one is sitting at my house in a box now though, so not sure they are going to allow it.

Thanks for the info

We have been running 5 of the Saijo Denki hybrids for just over 4 years - no issues to report. Very quiet, and very efficient. The only downside is that they need a water supply to the outdoor unit to achieve max. efficiency - in some applications that could be a challenge...

If the AC is for a bedroom or other area you wish to be quiet, don't forget to also compare sound levels from both the inside and outside units - on this front you'll probably find that Daikin and Saijo are the quietest.

Speaking to few Thai a/c technicians that have come to my place to fix my units I was told that Mitsubishi

is the best and most popular a/c unit that they will recommend....

OP, you weren't joking when you said that it was not pretty, it's hard to really decipher what's what..

the bottom line question is, what brand/size did you go for and why? this way it will be easy to

understand your research.....

Yep, Mitsu has a good reputation for reliability, but OTOH it's usually being compared against Samsung (biggest seller in TH), not to more upmarket brands like Daikin and Saijo. Mitsu definitely doesn't compete against those last two for efficiency or quietness, but it does on price

haha, sorry. I was really just sharing the method of just hunting down the spec sheets and compiling the info (screenshots since most of it seems to be in an image on company websites) of the relevant info in an excel sheet since it makes it easy to see it all together.

The stuff I learned (first time buying an a/c here) was:

1. Multiply the sqm of the room by 700-800 to get the needed BTU for the room depending on sun exposure

2. Doing the energy savings calculations will make you want to buy more efficient a/c's - here is a better calculator than that spreadsheet http://www.airinnovationsllc.com/energy-savings-calculator/ so pay attention to the EER rating

3. More efficient systems will pay for themselves in less than a year, most likely at bangkok electricity prices (about 5 baht per kilowatt hour)

I ended up with Daiken Smart Series for a 9000 and 24000 BTU units, and a Saijo Denki for the 36000 BTU unit. They are EER ratings of 18.04, 13.95, and 14.3 respectively. So, I am hoping that my electricity bill will be cut in half from my 20 yr old units that I had before.

Also, I can't believe how quiet those outside units are compared to my old ones. Almost can't hear them.
