RandolphGB Posted May 11, 2016 Share Posted May 11, 2016 I've seen a couple of shops using air coolers instead of air con. They said they were much cheaper to run and when I was inside it felt just as cool as a room with the air con switched on. Has anybody got experience of these? I've seen a couple from Hatari that look OK and are about 4,000thb - 5,000thb to buy. (http://hatari.co.th/en/products/aircooler-3.html) Link to comment Share on other sites More sharing options...
bkkmick Posted May 11, 2016 Share Posted May 11, 2016 Seen them but I always had the impression that they were just moving the air conditioning in the shop and not actually cooling themselves. I could be wrong. Link to comment Share on other sites More sharing options...
roamer Posted May 11, 2016 Share Posted May 11, 2016 (edited) Totally useless in a humid climate. At best they can lower temps by 2 to 3 degrees. In a humid climate they just introduce more water vapour into the air. Btw. Had one in the UK for "hot" summers, ended up on the rubbish tip.

sipi Posted May 11, 2016 Share Posted May 11, 2016 I have seen the argument that they are only adding water to the air. They work on evaporation. If you wet a face cloth and spin it around (or put it in front of a fan for a little while) then put it on your face, it will feel quite cool; even in humid climates. Try it. Evaporative coolers work exactly the same way. Link to comment Share on other sites More sharing options...
daoyai Posted May 11, 2016 Share Posted May 11, 2016 Humid climate? for the last 2 months here in Chiang Mai the afternoons have been about 15 percent humidity. Link to comment Share on other sites More sharing options...
lust Posted May 11, 2016 Share Posted May 11, 2016 I bought one for 9,000baht. Totally useless in Bangkok. It made my room feel extremely humid. The ones that you see in the department stores work well because they are inside with dry air conditioned air already. Waste of money. Link to comment Share on other sites More sharing options...

chrisinth Posted May 12, 2016 Share Posted May 12, 2016 I have a room at home that already has a 18,000 BTU aircon installed, but it was under calculated for the area. It still works, but the compressor runs for most of the time it is on, Do you think one of these coolers would be an option of extending the efficiency of the aircon, or better to replace the existing one for bigger?

ChristianBlessing Posted May 12, 2016 Share Posted May 12, 2016 In the desert southwest in the US we refer to these as "swamp coolers". During the driest parts of the year when humidity is under 40% they work well. During the monsoon season when humidity rises above 60% the evap cooler goes off and we flip on the air-conditioning to both dry and cool the air.

thai3 Posted May 12, 2016 Share Posted May 12, 2016 if they were any good people would not bother with A/C last one I looked at in a shop was pumping cool air at the front and emitting hot air from the back. They seem good in a shop, that's where they should stay! Link to comment Share on other sites More sharing options...

HerbalEd Posted May 12, 2016 Share Posted May 12, 2016 They work OK if you are near and directly in front of them. Otherwise, they won't cool a room. What really concerns me is the quality of water used in these fans. If there is live bacteria, mold or viruses in the water then they will be vaporized into the air for you to breath in.

noosard Posted May 12, 2016 Share Posted May 12, 2016 They are better than just a fan but not as good as an aircon They can not be used in a closed room unless you want a sauna or growth on the walls and ceiling Link to comment Share on other sites More sharing options...
Jedsada3 Posted May 12, 2016 Share Posted May 12, 2016 Hello, I've seen some air cooler with a "frozzen gel cartidge" at HomePro (the cartridge looks like the one you use in the coolbox).. The guy said that depending of the temperature of the air sucked by the fan, the air coming out wll be cool between one and three hours. Those coolers don't add water in the ambient air. They just cool it down,.. but you need a lot of cartridges (around 150 THB) and stay up to change it after 1-3 hours! Link to comment Share on other sites More sharing options...

A cooler box, and the associated blue "ice" blocks and a fan and some 4" plastic plumbing pipe will do the same thing Link to comment Share on other sites More sharing options...
NoshowJones Posted May 12, 2016 Share Posted May 12, 2016 You have to remember that the air in the shop is already cool because of the air condition, but this is a good topic, and I will be very interested to see how it goes. Link to comment Share on other sites More sharing options...
AlQaholic Posted May 12, 2016 Share Posted May 12, 2016 I have one of those. Completely worthless. You put ice in a box of water and the water circulates and evaporates, cooling down the room and also adding a shit load of humidity. The humidity adds to the heat effect. Plus they make a hell of a lot of sound which you cannot hear in the shop due to all other surrounding noise. Link to comment Share on other sites More sharing options...
denby45 Posted May 12, 2016 Share Posted May 12, 2016 if they were any good people would not bother with A/C last one I looked at in a shop was pumping cool air at the front and emitting hot air from the back. They seem good in a shop, that's where they should stay! You were looking at an AC unit. Not a cooler. You have to lead the air from the back outside by use of a hose. Failing to do that and you are just recirculating the air inside the room and wasting electricity. Den Link to comment Share on other sites More sharing options...
Paul Laycock Posted May 12, 2016 Share Posted May 12, 2016 Agree with AlQaholic, my wife purchased one and ended up giving it away. Link to comment Share on other sites More sharing options...
willyumiii Posted May 12, 2016 Share Posted May 12, 2016 I thought they worked well in the shop too. Then I realized that the shop was air conditioned. My experience out of the shop is that they do increase the humidity. So, if Thailand is not humid enough for you, it may be a good purchase.
