2020 Posted May 18, 2013 Share Posted May 18, 2013 The evaporative type, just to cool a room as opposed to a room air conditioner. Interior room with one interior door and one outside window. I believe they are not effective in areas with high humidity and my hydrometer is reading just under 60% so its not dry, but its not too moist either. Any good feedback would be appreciated before my eggs cook in my shorts. 2020 Link to comment Share on other sites More sharing options...
1Gringo Posted May 18, 2013 Share Posted May 18, 2013 I bought one from Home Pro. perhaps it'll work well in December. Link to comment Share on other sites More sharing options...
2020 Posted May 18, 2013 Author Share Posted May 18, 2013 I bought one from Home Pro. perhaps it'll work well in December. Oh dear, that's what I thought may happen. Might be a small aircon purchase for me soon then. Thanks for the honest reply anyway. Link to comment Share on other sites More sharing options...
hellodolly Posted May 18, 2013 Share Posted May 18, 2013 I don't know for sure how well they work but I do know they only work in a small area. Link to comment Share on other sites More sharing options...
ARISTIDE Posted May 18, 2013 Share Posted May 18, 2013 When buying an air con aim for a little higher BTU than required it will be more expensive, but it will save you money when power bill comes.

2020 Posted May 18, 2013 Author Share Posted May 18, 2013 I should have posted the room size to help with replies, but its about 3x3.5x2.4 metres brick. Good advice about the btu size, well received. Cheers 2020 Link to comment Share on other sites More sharing options...
NancyL Posted May 18, 2013 Share Posted May 18, 2013 I think they can augment, but not replace, a proper aircon unit in this climate. Link to comment Share on other sites More sharing options...
ARISTIDE Posted May 18, 2013 Share Posted May 18, 2013 (edited) There are some online BTU calculator here is one http://www.calculator.net/btu-calculator.html Watch out:- Sometimes Thai sale will recommend you a lower BTU air-con, many don't have the skills, ignore them and buy the BTU that you think fit your room - Determine the best position to put the compressor if you can. Believe it or not even some Thai professional don't know how to install it properly!! Check and recheck the work. Heres what happened to me before:+ Sometime they will install the compressor where rain water can flood or damage your compressor+ Sometime they will install it too close to the wall so your room won't get cool and expensive bills+ Sometime they will install it where it is hard to do the maintenance + Sometime they will drill the wall and f_uk up your wall so bad you need another repair! + Sometime they forgot to level the drainage properly so water from the air con reverse in to the air con and leak+ Sometime they forgot to install rubber at the base of the compressor so your wall shake like there's an earthquake + Sometime they will leave some minor problems so they can come back and charge you more! + Sometime they don't install the piping well so you need to do the refill more often Good luck Edited May 18, 2013 by ARISTIDE 1 Link to comment Share on other sites More sharing options...

DaamNaam Posted May 18, 2013 Share Posted May 18, 2013 No, they are as useful as an ashtray on a motorbike. Sorry but it's true. 2 Link to comment Share on other sites More sharing options...
bob89110 Posted May 19, 2013 Share Posted May 19, 2013 18000 BTU will work find and you won't have to worry about the heat load, this will also work great for 4X5X2.9. By the way, anything over 15% humidity in air will cause the evap cooler not to work very good, but it will increase the humidity. Evap cooler are great in the desert only not here in Thailand!!!This from a Air Cond person for over 30 years. 1 Link to comment Share on other sites More sharing options...
Naam Posted May 19, 2013 Share Posted May 19, 2013 (edited) I don't know for sure how well they work but I do know they only work in a small area. evaporating units do an excellent job in desert climates. i had a two-story house in Baghdad airconditioned by a ducted central unit. a disadvantage is the continous draft because it works on 100% fresh air to avoid humidity building up. some people might like draft the wide spread use of ceiling fans is evidence. personally i hate draft. p.s. i am not referring to the useless toys which are sold in Thailand.

Thighlander Posted May 19, 2013 Share Posted May 19, 2013 way too humid in cnx for swamp, but might work in the dry season. I had a house with central evap in Arizona. They are way better than aircon for price/cost to run/and ease of repair. Link to comment Share on other sites More sharing options...
scorecard Posted May 19, 2013 Share Posted May 19, 2013 (edited) No, they are as useful as an ashtray on a motorbike. Sorry but it's true. Agree, about as useful as a wheel on a walking stick. cool if you sit within one metre or less, directly in front of the output vents of the evaporative machine, but any further away and there is no cooling effect at all.

highonthai Posted May 19, 2013 Share Posted May 19, 2013 They only work in a dry climate, such as a desert. But they also add to the humidity. A fan works better in a humid area. Link to comment Share on other sites More sharing options...
ARISTIDE Posted July 9, 2013 Share Posted July 9, 2013 (edited) Just to support my points. At first the air conditioning guy tried to installed the compressor unit the easy way, in the small space between concrete beam and the wall. My father said the space will be too confined and the rain could flood the compressor unit and asked him to installed it above the concrete beam. + Sometime they will install the compressor where rain water can flood or damage your compressor+ Sometime they will install it too close to the wall so your room won't get cool and expensive bills Edited July 9, 2013 by ARISTIDE Link to comment Share on other sites More sharing options...
