Which of the following is NOT classified as a Type I appliance?

Type I appliances are defined as small appliances that typically use refrigerants in lower quantities and are often designed for residential use. They include devices such as room air conditioners, household refrigerators, and household freezers. These appliances are characterized by their ability to operate independently and are generally not integrated into larger HVAC systems.

A central air conditioning system, on the other hand, falls into a different category. It is categorized as a Type II appliance because it is designed for larger-scale applications and often contains refrigerant in higher quantities. Central AC systems are generally used to cool larger areas and can be part of an integrated system that serves multiple zones or buildings.

Recognizing this distinction helps to identify which appliances qualify for Type I classification. Therefore, central air conditioning systems are not classified as Type I, highlighting their complexity and the greater volume of refrigerant they involve.
