How to Stay Cool with a New Portable Air Conditioner(For the models comply with the
requirements of Department Of Energy in US)
Because of a new federal test procedure for Portable Air Conditioners, you may notice that the
cooling capacity claims on portable air conditioner packaging are signi cantly lower than that of
models produced prior to 2017. This is due to changes in the test procedure, not to the portable
air conditioners themselves.
What should I look for rst when purchasing a portable air conditioner?
The right air conditioner helps you cool a room e ciently. An undersized unit won't cool adequately
while one that's too large will not remove enough humidity, leaving the air feeling damp. To nd
the proper air conditioner, determine the square footage of the room you want to cool by
multiplying the room length by its width. You also need to know the air conditioner's BTU (British
Thermal Unit) rating, which indicates the amount of heat it can remove from a room. A higher
number means more cooling power for a larger room. (Be sure you are comparing only newer
models to each other- older models may appear to have a higher capacity, but are actually the
same). Be sure to "size up" if your portable air conditioner will be placed in a very sunny room, in a
kitchen, or in a room with high ceilings. After you've found the right cooling capacity or your
room, you can look at other features.
Why is the cooling capacity lower on newer models than on older units?
Federal regulations require manufacturers to calculate cooling capacity based on a speci c test
procedure, which was changed just this year. Models manufactured before 2017 were tested under
a di erent procedure and cooling capacity is measured di erently than in prior years'models. So,
while the BTUs may be lower, the actual cooling capacity of the air conditioners has not changed.
What is SACC ?
SACC is the representative value of Seasonally Adjusted Cooling Capacity, in Btu/h, as determined
in accordance with the DOE test procedure at title 10 Code of Federal Regulations (CFR) 430,
subpart B, appendix CC and applicable sampling plans.
