There may be two problems, one is your improper A/C ton capacity selection which is unfit for the area you want to be cooled. Try lowering the thermostat by five and check whether it works. If these won't work call a professional AC service. (greensandal.ae)
12,000 btu of cooling capacity.
A ton is the amount of cooling capacity (power), not energy. 1 ton is equal to 12,000 BTU/hr.
Technically you need one ton of cooling for every 400 square feet, but it is always best to slightly undersize your unit, as it will be more efficient and have a longer life span. I would go one ton of cooling for every 500 square feet .
you can not measure the ampres on the cooling capacity of the system. you can only measure ampres on the size of compressor or input kw to air-con. 1.5tons is measuring cooling capacity not electrcity input.
if by how much you mean the heating or cooling capacity it is 60,000 BTU/hour
The formula is simple. One ton of cooling equals 12000 btu. So a three ton A/C has a 36000 btu capacity.
How many CFM for one ton of cooling
Cooling capacity of 30,000 btu per hour. That is the nominal total of both sensible and latent heat.
The capacity and efficiency would be mostly governed by your indoor coil. When you have a mismatch with the indoor unit being smaller, you will have higher operating costs. The outdoor unit has to work harder to generate the same amount of cooling. This is not a good thing.
As i found: A measure of the effective cooling capacity of a refrigerator, expressed in Btu per hour ot in tons, where one ton of capacity is equal to the heat required to melt 2000 pounds of ice in 24 hours or 12000 Btu per hour.
"ton réfrigérant" = "your cooling liquid" (as in fridges or A/C)
1 ton of cooling in 12,000 btu's
