Can anyone give me a approximately figure on the normal range electricity unit usage for 30 square meter bedroom with a 18BTU air condition only used at night i.e. 7-8 hours night. Room not airtight, but done what I can to make it so. The room has one small window and air-balcony.

An 18,000 BTU A/C will use 1.5-2 units per hour if the compressor is running continuously depending upon age and efficiency of the A/C unit.

What set temperature are you using? 18C => 2 units an hour 26C => 1 unit or less per hour.

Assuming you're paying government rates one unit costs about 4 Baht.

because Klingons do not use yewnits. we measure bloodwine in liters or m³ at glorious reunions, resistance of our ridged foreheads in kilopond per cm² (the Klingon Empire went metric when the ancestors of the [immigrated] nowadays Aussies were still living in European caves and measured distances in pound of raw mammoth meat per pedestrian mile), the output of our disruptors are rated in megajoule and the sexual prowess of Klingon females in megatons.

Thanks for the replies.

20C and running continuously for 7-8 hours each night. Measured 14 units for 8 hours so I guess I’m inside the accepted norm!

You may want to try a common fan on low, not scientific, but I would guess that you could then select it to about 24'c and save the compressor form kicking in as much. the feeling of airflow over you is the same.

Thanks, but I have tried that and its fine for the living room but in the bedroom at night I have to get it more constant cool. Now when it’s a cold spell over most of Thailand I usually wake up to 18C and feel that’s okay but then again back in Europe in the summer time a bedroom temperature in the morning at +18C would feels warm.

Oh I see, You are European, choose to live in the humid tropics and the bitch about the cheap electricity you get to power you air con and think that 18'c is warm.

OMG, I can't believe I used reasoning to use logic Thailand ......

Nothing personal, just made my day. I also love AC in Thailand, Rarely gets below 26'c, on a serous note, any money spent on any kind of insulation, seems to make a genuine difference. I clean my compressor "grills" twice a month and a deep clean of the internal one twice a year. Apart from filling holes, insulating your ceiling, (in a condo, not much you can do ? you all ready have a great roof above) put efforts into cleaning it. If you are in Bangkok, get a deep clean of your out side compressor. My last condo in BKK, avg pre clean was 5600b a month, post clean 3150b. What more can I say. You should have seen the amount of shit that came out of it, really wish I videoed it to post a link, it was unknown when it was last cleaned though.

Where shall we go....Europe is broke and so is North America.....BTW, wasn’t the Portuguese and French some of the first Westerners down here in SEA.

But yes in March /April I feel very well where I’m from!

Regarding the air condition and one of the reasons that the initial question come up. The landlord changed both of our air condition systems a few months back. It was planned and I know about it but I was in Europe when the work got done. Any way I could only see a plus with a change. However what I got a bit skeptic about when returning was that the outside units were moved from the wall to the roof. With other words constantly in the sun compared to the wall where it’s at least is shadow half of the day.

Does it make any difference?

Thanks.

My AC is set at 16 C, every night. Only down side is that I can't see out of my bedroom windows in the morning for the outside condensation.

We need to burn some fuel, my friend.

NB: It takes about 300 g of fossil fuel to generate 1 KWh

My room is about 33sqm, use about 430baht per month, also use of a Shower unit in the attached bathroom, and the wife's hairdryer now and again, sometimes a TV.

You never cook and live in total darkness without a refrigerator?

yep, my glass of water next to my bed was frozen some mornings, always open window despite minus 20C outside

Now I m happy with aircon at 26C

occasionally 23 in the car

all my bedrooms are same size, approx 29sqm including bathroom, and each room has its own electric meter, and when we have house guests, especially my mum and dad running AC at 21C, electric consumption double for that room

I have two adjoining condos, with 2 seperate meters, one is the bedroom with a bathroom, the other is living area and dining area as well as a small kitchen area and another bathroom with a washing machine.

Okay I forgot the lights!!
