sam sen Posted February 9, 2014 Share Posted February 9, 2014 i've never bought an AV unit before... i'm looking at buying and air conditioner for a small room - 9m/sq have been to a couple of shops and have been recommended the Daikin, model FTKS09JV2S - its not a brand i am familiar with, anyone bought one? i was told it has an 'inverter' that will save 40% on electric usage - is this true? anything i should check about when buying and an conditioner? any recommendations? thanks Link to comment Share on other sites More sharing options...
WitawatWatawit Posted February 9, 2014 Share Posted February 9, 2014 Daikin are a good brand and maybe the most quiet from my experience. Power usage seems to be very good compared to the LG in my daughter's room. During the hot season, my power bill goes up by about 500 baht a month, but when my daughter is here, it rises by another 700-800 baht. 1 Link to comment Share on other sites More sharing options...
OMGImInPattaya Posted February 9, 2014 Share Posted February 9, 2014 You'll fund lots of helpful advice in this topic in the housing DIY subforum. In fact, mods should move this op there. 1 Link to comment Share on other sites More sharing options...
mogandave Posted February 9, 2014 Share Posted February 9, 2014 I think the Mitsubishi is the best unit. 1 Link to comment Share on other sites More sharing options...
Popular Post bonobo Posted February 9, 2014 Popular Post Share Posted February 9, 2014 I think the Mitsubishi is the best unit. I agree with that. My only regret is that I did not get the inverter model for my home. My neighbor, with the exact same home floorplan, saves about 1,000 baht a month over me even when she runs the air far more than we do. 4 Link to comment Share on other sites More sharing options...

Popular Post Naam Posted February 9, 2014 Popular Post Share Posted February 9, 2014 buy an inverter unit! the food prepared in your kitchen will be tastier, your dogs will stop drooling, your grass will get greener and your wife/girlfriend will want more sex. that's the summary of umpteen postings on aircons in Thaivisa. only postings of eggsburts considered (especially of those who possess a wealth on no idea as far as applied thermal physics is concerned). oh well... 8 Link to comment Share on other sites More sharing options...
bankruatsteve Posted February 9, 2014 Share Posted February 9, 2014 For that size room, you only need 7-9K BTU (which is the smallest available that I've seen) and those almost never come as inverter model. (b/c it just wouldn't make sense for that small a unit). Link to comment Share on other sites More sharing options...

Satcommlee Posted February 9, 2014 Share Posted February 9, 2014 Only Inverter type aircons will really offer any cost savings. I just bought some Samsung Smart Inverter aircons that have been on offer lately, have a look for them.. They have Smart Inverter and virus Doctor logo's.. I paid about 15K for a 9000BTU and 18K for I think a 11000BTU (including Installation) at the MALL in KORAT (POWERMALL), they were also on offer in Homepro.

mogandave Posted February 9, 2014 Share Posted February 9, 2014 Getting a correctly sized unit will save more money than anything. An undersized inverter unit running constantly user as much power as an undersized non inverter unit.

Crossy Posted February 9, 2014 Share Posted February 9, 2014 An inverter will only offer significant consumption savings over a conventional unit when it is running at less than capacity, i.e. it is somewhat over-sized for the current conditions (maybe cool weather). Our OP has a room that is rather small for the smallest A/C units commonly available, so a 9000 BTU inverter unit is probably the best choice if the room is in constant use. The Daikin he's been recommended is a good fit. If it's a spare room, bang in the cheapest 9000BTU (or thereabouts) conventional unit. Link to comment Share on other sites More sharing options...
Andre0720 Posted February 9, 2014 Share Posted February 9, 2014 (edited) Air Conditioners Inverter vs. Non Inverter The question is which is right for you Inverter or Non Inverter? The difference between inverter and non inverter is the inverter units can alter their speed in response to cooling demand. Some units have an initial over-speed period where they will run at a slightly higher capacity for a set time to pull down the temperature of a hot room. When they reach the set point temperature they can reduce capacity to maintain that level without cycling as much as a normal unit would. This saves power although it’s arbitrary as it would still take a while to recoup the increased purchase costs. The inverter unit increases the power usage slightly as it converts the incoming power into a suitable style for the air conditioner although the ability to run at a reduced power level helps to drop the overall usage to below that of a typical non-inverter unit. Most of the advertising claiming 30% lower bills using inverters are based on very carefully set up laboratory scenarios. In reality, while they may cost less to run than a conventional unit, buying an efficient conventional unit will still be cost effective.

rbmcn Posted February 9, 2014 Share Posted February 9, 2014 I bought a unit in an estate in Mae Onn. The builder supplies "Star-Aire" a/c as standard. Never heard of them before . I hear rhem now. They are rhe noisiest a/c I have ever used. I have lived in South East Asia for almost 30 years and have some experience with a/c. Stay away from Star-Aire or invest in earplugs. Cheers.

fxe1200 Posted February 9, 2014 Share Posted February 9, 2014 yes Daikin inverter is great! I agree, the Daikin is a real saver. Try to get a workshop manual, then you can service the unit by yourself (except checking the pressure of the cooling gas, mostly R-134A). Regular cleaning, twice or three times a year, depending on the usage, is inevitable. Link to comment Share on other sites More sharing options...
