Which of the following units would a technician correctly classify as a small appliance?
a.A 7.5-ton rooftop packaged air conditioner
b.A factory-sealed water cooler holding 3 pounds of refrigerant
c.A supermarket refrigerated display rack
d.A residential split-system heat pump charged on site
解析
A factory-manufactured, hermetically sealed water cooler with five pounds or less of refrigerant meets the small-appliance definition. Rooftop units, supermarket racks, and field-charged split systems are larger, non-sealed, or assembled on site and are Type II or Type III equipment. Typical small appliances include refrigerators, freezers, window units, dehumidifiers, PTACs, and vending machines.
