Thermodynamically Speaking: Should I keep my house at a constant temp to save money?

to the title ... I'm kind of partial to 26C, and once at temp, good inverters don't use much electric at all.

 

Yeah 26 for me too.

 

3 AC's.... Average 4k a month, glad I do not have to pay the bill !

Before solar, our PEA bill was 3-5k a month, just 2 ACs (24k & 13k BTU). That's before we had BEVs.  That's another 3-5k saved a month vs petrol. 

 

Making ROI rather quick, along with being quite comfy, year round.

I was paying about that for my relatively small Bangkok apartment with 2 A/Cs.  But that's mostly because I chose to live on the top floor of a 5 story Asoke area building (that's rare in itself).  The view, access to the roof, and having no noise from upstairs neighbors was worth it.  YMMV, obviously.

From a power cost standpoint, you are correct.  But if you have barely adequate cooling capacity, you may have to leave your AC running all the time to reach and maintain your desired temperature.  I don't know anyone who installs enough cooling capacity to keep a Thai house at 20 C without running all the time.

 

Long story, I once had an apartment in Corpus Christi where I had to leave the AC running when I was at work because if I just turned it on when I got home, the temperature didn't drop until long after my bedtime.  I complained to management and they sent guys over to test the system and told me tough noogies.  It's working fine.  And it was sized according to the prevailing specifications for that size apartment.  That was before programmable thermostats became so common.  Had I been able to turn it on a few hours earlier, it may have been okay.

 

 

20⁰ is totally unnecessary though

I'd be shivering.  But, to each his own.  A man's icebox is his castle.

I reckon gammagobarse is full of it claiming he runs that temp.

Of course it isn't, common sense should tell you that, do some research and come back to the table

 

Please do the research.

You are mistaken.

Maybe you did not....

Before you met me.

 

I have 70,000 BTU of cooling capacity.

This is just the right amount.

 

Not too hot, and not too cold.

 

Just like Goldilocks.

If you contract with a local villager you can get free range chickens, however the chicken breasts will be considerably smaller than the cage farmed chicken you will usually get.

 

I will check this out.

Your presumption is completely WRONG, in this case.

37 outside and 19 inside

 

 

However, I choose to forgive you, this time.

I recommend 22c for the most frequently used rooms and 28C for the other rooms.

Not good.

 

There is a HECK  of a lot of thermal energy stored in the walls of a brick house.

 

If this were a paper shack, like they have in America, then it would not matter.

 

The walls of plasterboard, or gypsum board, do not store much thermal energy.

 

However, a ton of bricks is a  ton of bricks.

 

It requires a LOT of cooling to cool down many tons of bricks.

 

But, once you get the bricks cooled  down, then much less energy is required to maintain the desired temperature....

 

Thermodynamically Speaking....of course.....

I think its amazing you can be so silly. American houses are insulated to a degree you would not even understand. Little to no insulation in Thai houses, maybe some in the roof of some. 

 

What you have written  is sheer stupidity. Have a look at a typical insulated American house.

What else do you expect from the OP?

It is at least consistent in the cr@p it posts!
