What is classified as a type 2 appliance in refrigeration systems?

• A. Small appliances with less than 5 lbs of refrigerant
• B. High pressure appliances under 50 lbs of refrigerant
• C. Very high pressure appliances with more than 5 lbs of refrigerant
• D. Refrigeration units that require no repairs

Answer: (C)

Type 2 appliances in refrigeration systems refer specifically to very high-pressure appliances that contain more than 5 pounds of refrigerant. These systems generally use refrigerants that fall into the category of high-pressure gases, such as those used in certain types of commercial refrigeration, chillers, and larger cooling systems.

This classification is important because it stipulates the certification requirements for technicians who handle these appliances. Technicians must be familiar with the safe handling practices and regulations associated with high-pressure refrigerants to minimize risks during repairs and maintenance. Other options do not fit the definition of Type 2 appliances, focusing either on lower refrigerant capacities or appliances that do not require repairs, which do not align with the established classifications used in EPA regulations.
