Does the outdoor unit start and stop (conventional) or vary speed continuously (inverter) once the room is down to the set temperature?

 

Do note that inverter compressors do have a minimum speed below which they stop, so if the cooling load is small for the unit size you'll see it cycling.

 

Yes, I can clearly hear the change of pace during its drive.

Specifications of  the A/C in my room.

Has been used since Nov.2005.

It was already here when I checked in.

 

Thai texts into English with google translate.

 

Any comments from the electrical experts Welcome.

Love where it says Types and Quantities of Drugs. And two EER readings.

Please just do math.

Check for the heat output in BTU/h

Divide by watts.

You get EER in BTU per hour divided by power used, in watts.

Just did that on my new TCL Elite 12000 unit. After settling down for about 10 minutes, it is maintaining 600 watts @ 28C. So its EER must be 12000/600 = 20. Good eh?

NOPE.

 

That cheap AC that you bought...the TCL Elite 12000 has a EER that sucks the big one.

 

The SEER is only 16.

 

You need to check the side of the outdoor condenser unit.

There, you can find the numbers you need to calculate EER.

 

But, as I say....the Elite 12000....

Sucks the BIG one, BIG TIME....

The SEER is only 16.

After much Googling around, I find that SEER 16 is good for an average costing, using air-con unit. The numbers to calculate the EER is BTH/watts. Mine is 20.

I am happy with mine.

Sorry.  But this is baloney.

You need to use the rated maximum power in watts.

Then divide that number into maximum heat output (from the hot coil).

If this is beyond you, then please do not confuse others.

 

SEER of 16 is GARBAGE for a modern AC, in the year 2024....

 

12000 BTU is a very small AC.

So, a good SEER should be above 23....

 

And, this ain't no baloney, boy......!
