Right now the room temperature is 28 - 29C, so no aircon.Less fan power requires cooler numbers. I set my room climate so that I can sleep on top of the sheets and not sweat. It's a bit silly to cool the room down so that I have to use blankets to stay warm LOL. If the humidity is high, I may have to drop the aircon setting down a degree. You are right i guess, though I like it how i do it now. I can't place a ceiling fan in my bedroom. The roof plate is too thin. It would have been a good idea otherwise. Im not too bothered about my electricity bill. Less is always better but its not the most important thing ever. Link to comment Share on other sites More sharing options...

In Saudi the AC cooled outside air that was blown into the room. I'd assume such was available in LOS if one really wanted one. the aircons you are referring to blew only a small percentage (3-5%) of outside air into a room when a little flap was opened by a lever. some manufacturers designed their units that the same amount was exhausted from the room and replenished because of the difference in air pressure.

jak2002003 Posted January 25, 2018 Share Posted January 25, 2018 Acclimatise yourselves to the weather here! We never have air con turned on in the daytime... only when its the crazy hot season and temps go through the roof. When we have it on its always set to 26 - 27. At this temperature it is very comfortable, economical, and better for the environment. If we were to set it down to 24.. then go outside we would get a huge shock to the system. At night just have windows open, and a fan on. People saying they can't cope if the temperature is over 24 need to go live in a cooler country!

Most of what you said was reasonable, but that last comment was absurd. This is not the jungle. Air conditioning is commonplace in most establishments and most houses have them so even the people who can't cope with high temperatures can live comfortably. Obviously, Thai people born in this hot climate love aircon too.There is a difference between coping and living comfortably. I don't think most expats came here just to "cope". If you came here just to "cope", then perhaps you need to move to another country where you can really enjoy your life. Link to comment Share on other sites More sharing options...

Money was not the issue it was the land lord that did not want them installed. I NEVER acclimatized and hated it always when it was hot. Now I got an airon in each room i use (except kitchen) and i use them whenever I want. People are different.. what people are willing to spend money on varies. Your life your choices mine are different. What temperature do you set your gym to? There were a few days last month and this month where I could train without aircon as the gym temperature fell below 26C, the temperature I keep my gym at when I train, but with fans blowing too.

Depends on the A/C unit. For the best in filtration...... a regular A/C unit won't filter the air much at all except for large stuff. You would need to shell out the big bucks for the best A/C unit on the consumer market. As for oxygen..... in the tropics I just open the screened windows. How would a split style air conditioner, the most commonly used here, bring in fresh filtered air from outside? All the airconditioner brings in from outside is cooled refrigerant from the outdoor unit (housing the compressor, condenser, fan and expansion valve) through an insulated copper pipe. The Indoor unit sucks in hot room air that rises through an air filter and cools it down by heat exchange and blows out cool air. It just circulates the air in the room. If the room is completely sealed the oxygen level will fall. The only way fresh air gets in is through gaps under the door unless you allow fresh air in through a window or other vent.

Leave a window slightly open, for example. It will cost a bit more to cool the room, but your air will be fresher. The old style wall units used to have vents to the outside, but the new split style can only circulate the air in the room. Yes but, Sliding insect screens on doors/windows? What happened to them...

Thanks wrong! the wall/window units had all a small lever which opened or closed a little flap in the partition which separates evaporation section from condensing section. depending on the manufacturer, the location and the design of this flap a small amount of outside air was added to the recirculated room air or sucked out. American made units sucked air, Japanese made units blew in outside air. Link to comment Share on other sites More sharing options...

Any amount of outside air is preferable to none at all, as with the AC here. Unless I open a door/ window at some time of the day, I'm breathing stale air with elevated CO2. OK at the moment when it's cool, but not going to happen when it gets really hot. PS I never have AC on when I'm sleeping as fan is sufficient, but unfortunately, some hotels only have AC ( and duvets ). Link to comment Share on other sites More sharing options...

Don't have heaters and acclimatise to the cold No. Because people can die from hypothermia.. and indeed many old people in the UK die each winter as they can't afford to have the heating on. I have yet to hear about large numbers of farangs dyeing here because of no air con in the bedroom. The more people use air conditioning set a very low temperatures, the worst they are going to feel living here when they step outside, or have to make do without air con for some reason. Using the air con is good to get the humidity out of the air for a more comfortable nights sleep, but that does not mean the unit has to be turned down to under 25. I know people have it set to 16..!! That is not even possible for the room to get that cold.. and means the machine is running constantly.. using up huge amounts of energy.. and is very wasteful and also bad for the environment. Once you start having the air con on at higher temperatures your body will acclimatise to the weather here much better, and you will be more comfortable in the long run. Now, having mine on at 27 is cold enough.. and I often switch it off as I get too cold. It's only ever on in the hot season too... because even I find it uncomfortable when the temps get over 35.

It nearly exclusively cooled down hot air from outside. I had to them close them off to cut down on my huge electric bills. If I ran these full time as they were originally set up my bills would be 10 - 20k a month using just one unit and I have 6 like this. Link to comment Share on other sites More sharing options...
