jaideeguy Posted May 17, 2013 Share Posted May 17, 2013 My usual tactic to beat this damn heat is to set my aircon at 25c and run it at night, then wake up freezing in an hour, then turn it off and wake up sweating and maybe repeat this 2 more times during the night, making for an interrupted sleep. Last night, I tried a different tactic and set the control at 28c and slept comfortably the whole night. Just wondering how much more this is costing me in elect?? Another stupid question is 'where is the sensor for the temp......in the remote controller or in the blower unit'?? Link to comment Share on other sites More sharing options...
Gsxrnz Posted May 17, 2013 Share Posted May 17, 2013 (edited) The sensor is in the blower unit if you have a remote control. It might be in the control unit if it's fixed to the wall in some of the more expensive cassette type units. You'll find that the temperature setting/display is never correct or true and therefore should be set to your comfort, irrespective of what the display shows. I have one in the bedroom set for 29 and it's comfortable. The one in the living area needs to be set for 22 for the same comfort level. I bought a thermometer from Tesco and did some comparisons in the two rooms - it appears my comfort level is actually 26 as that was the "true" reading in both rooms according to the thermometer. Of course, I'm sure if I bought 3 more thermometers they would all give different readings as well. But using my single thermometer proved that the actual air con digital displays are inaccurate in a comparative context. EDIT: As to the cost - I figure the comfort is worth whatever it costs. Your air con is costing virtually the same per running hour whether you have it set on 18 or 28. The difference being that it will be running more on 18 than 28 to maintain the lower temperature, and the compressor will be costing more than just the internal fan when it goes into "idle" mode when set higher. If you're using it all night or all day then just go for the comfort level - cost differential will be marginal.

How odd that you would have an air con unit and feel the need to break from your sleep to keep adjusting the god dam thing all night,surely this defeats the object of having one in the first place. If I worried so much about the cost and setting I wouldn't even contemplate owning one in fairness,why not just use a fan ? Seriously find the temperature you like and leave it at that,it's really that simple,most modern units come with a sleep setting that adjust as the night progresses.

jaideeguy Posted May 17, 2013 Author Share Posted May 17, 2013 If I just use a fan, i get a chill on the exposed side and sweat on the unexposed side and am spinning all night long. Re, the sleep setting......how does that feature work?? my new Samsung has a 'good sleep' setting. There is a timer on the remote, but instructions are in Thai only. In the 13 years that I've lived here, the longest that I've run my aircon is 1 hr, but this year it's not cooling off at night. This morning's cool was 84f.........thanks Al Gore!! 1 Link to comment Share on other sites More sharing options...

Google the model number and you're guaranteed to find an operator's manual in English available for download. Or post the model number and I'll track it down for you.

NanLaew Posted May 17, 2013 Share Posted May 17, 2013 If the OP's airconditioning is 'suddenly' inadequate after 13 years of use, it probably needs cleaning and servicing. 1 Link to comment Share on other sites More sharing options...
pinfold Posted May 17, 2013 Share Posted May 17, 2013 Set mine at 27 before sleep,(28 too hot)but wake up in night too cold, remedy was set the AC on timer for 3 hours then fan set on another timer that cuts in when AC shuts down,bit of a juggling act but it works well Link to comment Share on other sites More sharing options...

richardjm65 Posted May 17, 2013 Share Posted May 17, 2013 To extend this subject a bit more, I was once told that running the ceiling fan (on low), together with the a/c, was cheaper and more efficient than running the a/c unit alone - something to do with a more even spread of the cold air. Any comments? Anyway, with the ceiling fan running, I run the a/c at 27 degrees, (starting about an hour before bed), then knock off the a/c about 3.00am when I get up for a pee. That seems to work quite well for us, the coolness seems to persist with just the ceiling fan running. I think the key is to ensure that the a/c is also drawing out the humidity. I can't be dealing with humidity when it's either hot or cool. Link to comment Share on other sites More sharing options...
naboo Posted May 17, 2013 Share Posted May 17, 2013 One fan between the three of us, point it at the wall half way through the night as we're freezing. Air con, in April only, set to 26C all night adds 500B to the bill, not a reason to worry about the cost. No, the third one is the baby, not what you were thinking. 1 Link to comment Share on other sites More sharing options...

Will2011 Posted May 17, 2013 Share Posted May 17, 2013 25c all night is good for me. In western countries, we say a bedroom shoudnt get hotter than 19c for health reasons. Link to comment Share on other sites More sharing options...
bangkokstick Posted May 17, 2013 Share Posted May 17, 2013 Most of the people set aircon too cold without even knowing why ! They do not try to put it hotter. When it is 33 outside at night 28 in the room with aircon is far enough. Another good solution seems to cold the room as much as possible before sleep them stop aircon and use fan. Both ways comfortable for me but I have been one of these stupid who put 25 all night without even knowing why :-) Link to comment Share on other sites More sharing options...
jaideeguy Posted May 18, 2013 Author Share Posted May 18, 2013 The reason that the temps stay so hot all night is we live in these cement 'heat sinks' that absorb and store the heat in the walls and especially those terrible cement roof tiles, then radiate it down on us all night. The coolest houses here are the old style grass roof and bamboo walls and floors, but they are so messy and attract insects. 1 Link to comment Share on other sites More sharing options...

I can't be dealing with humidity when it's either hot or cool. I have found I can definitely control my cold air. When I am on the bed, I point the fan (which sits under the air) at the bed. The other side of the room is warm. I am sure a lot of people do this. I have noticed, more to the op's question, that leaving the ac on for long periods and using a higher (yet still comfortable temp) saves energy. I don't think the numbers mean much switching from one ac to the next, but I have found 28 on mine is perfect. The compressor really does not kick in very often, which tells me the ac isn't working too hard at all to keep that temp. I just make sure I am done with opening the doors and stuff like this before i turn mine on, i'm quite the miser, but why the hell not, it's good for the environment too.

I personally think that it is largely due to higher relative humidity at night. You will see the temperature drop, yet feel the same. It is just the relative humidity increasing. I am actually hotter at night after it has "cooled off" here in BKK. It is terrible. Edited May 18, 2013 by utalkin2me Link to comment Share on other sites More sharing options...

bluemoon58 Posted May 18, 2013 Share Posted May 18, 2013 Not that cost of running a/c bothers me one bit but me and "her indoors" have found that putting the a/c on for half an hour before going to bed, then putting the tall fan on us right at the foot of the bed, gives us both a comfortable sleep. At the end of the day though, it's horses for courses... Link to comment Share on other sites More sharing options...

bonobo Posted May 18, 2013 Share Posted May 18, 2013 I just installed soem air cons. I was told that one room needed 24,000 BTU. The mooban staff told me to get two 12,000 BTU air cons instead, that they would work better. When the Mitsubishi guy came to install, after the fact, he asked me why I did it that way, that the architect designed it for one 24,000 BTU unit. I am finding that the two smaller units are having problems pushing the air far enough, so I now use a fan to help circulate the cool air. Link to comment Share on other sites More sharing options...
jpinx Posted May 18, 2013 Share Posted May 18, 2013 The downside of A/C is the lack of fresh air. I'm considering ducting air from outside to the "suck" vents on the ac unit. Anyone tried that? Link to comment Share on other sites More sharing options...
