Which of these counts as a small appliance under EPA's definition?
A window air conditioner is named as a small appliance.
- A factory-sealed window air conditioner ✔
- A supermarket refrigeration rack
- A centrifugal chiller
Why: EPA's definition lists room air conditioners, including window units, as small appliances. They come charged and sealed from the factory with five pounds or less. Racks and chillers are far larger and are built or charged in the field.
Huh, didn't know that: Medical and industrial research refrigeration equipment can also be small appliances if they meet the five pound limit.
What do computers and air conditioners have in common? They both become useless when you open windows.
