What is the difference between BTU DOE and BTU ASHRAE?

What is the difference between BTU DOE and BTU ASHRAE?

ASHRAE reflects the old testing standards when portable ACs were tested in the same way as window units. The DOE found numerous inefficiencies specific to the portable units and began using new testing methods. The DOE rating should be used when considering which unit to buy for the square footage it is needed for.

Do portable AC units use a lot of electricity?

How Much Electricity Does A Portable Air Conditioner Use? Mid-sized portable air conditioners use an average of 2900 watts per hour. Particularly large units can exceed the electricity usage of even central air conditioners, expending about 4100 watts per hour.

What does DOE mean on a portable air conditioner?

‘The Department of Energy (DOE) is proposing new efficiency rules for portable air conditioners that are expected to save consumers billions of dollars on their energy bills….’

What does ASHRAE mean in air-conditioning?

ASHRAE, founded in 1894, is a global society advancing human well-being through sustainable technology for the built environment. using its full legal name of the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

What does DOE and ASHRAE mean?

The label on portable air conditioners must follow a new rule from the FTC (Federal Trade Commission) that requires a listing of the older, ASHRAE rating, as well as a new rating from the DOE (Department of Energy.) The reason for the difference in the two ratings is due to how a portable AC works.

Does a portable AC use less electricity?

Depending upon its size (cooling capacity in Btuh), using a portable air conditioner may use just one-eighth as much electricity as your central air conditioner. For example, there is no need to keep the entire house cool at night when you can run a portable air conditioner in your bedroom.

What does ASHRAE mean?

using its full legal name of the American Society of Heating, Refrigerating and Air-Conditioning Engineers. Use of ASHRAE reflects the Society’s worldwide membership and that services will continue evolving globally.

What is the difference between SACC and ASHRAE?

SACC Ratings Models manufactured before 2017 were tested under a different standard (ASHRAE) that produced a higher cooling capacity output. While the SACC BTU’s are lower than the previous ASHRAE BTU’s, the construction and cooling capacity of this model(s) remains unchanged.

How many BTUs do I need for an air conditioner?

Based on size alone, an air conditioner generally needs 20 Btu for each square foot of living space. Other important factors to consider when selecting an air conditioner are room height, local climate, shading, and window size. Verify that your home’s electrical system can meet the unit’s power requirements.

Is ASHRAE’s information accurate and reliable?

While every effort is made to provide accurate and reliable information, this is advisory, is provided for informational purposes only. These are not intended and should not be relied upon as official statements of ASHRAE.

What is the required cooling capacity for a room air conditioner?

The required cooling capacity for a room air conditioner depends on the size of the room being cooled — room air conditioners generally have cooling capacities that range from 5,500 Btu per hour to 14,000 Btu per hour. A common rating term for air conditioning size is the “ton,” which is 12,000 Btu per hour.
