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 significantly 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 first when purchasing a portable air conditioner?
The right air conditioner helps you cool a room efficiently. An undersized unit won't cool
adequately while one that's too large will not remove enough humidity, leaving the air feeling
damp. To find 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 specific
test procedure, which was changed just this year. Models manufactured before 2017 were
tested under a different procedure and cooling capacity is measured differently 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.
