AI Explanation
The correct answer is A) a hermetically sealed water cooler with a 2 lb. refrigerant charge. Under the EPA Clean Air Act rules, a "small appliance" is defined as any appliance that uses a refrigerant charge of less than 2 pounds. A hermetically sealed water cooler with a 2 lb. refrigerant charge falls within this definition. The other options, such as a self-contained walk-in freezer, a split air conditioning system, and a large chiller, all have refrigerant charges that exceed the 2 lb. limit for a small appliance.
