Definitions: practice questions
Our EPA 608 Type II bank has 14 questions on this topic. Here are 5 of them with answers; the full mock exam draws from every topic, like the real one.
Question 1
Which refrigerant is a high-pressure refrigerant?
- R-123
- R-1233zd
- R-11
- R-410A
Show the answer
D. R-410A — Low-pressure refrigerants such as R-11 and R-123 are used in chillers (Type III).
Question 2
On high-pressure appliances with more than 15 lb of refrigerant, which type of recovery equipment must be used?
- A recovery bag
- No equipment; vent it
- Self-contained (active) recovery equipment
- System-dependent (passive) equipment, using the appliance's own compressor
Show the answer
C. Self-contained (active) recovery equipment — System-dependent equipment is limited to appliances with 15 lb or less.
Question 3
Which equipment is covered by Type II certification?
- Low-pressure centrifugal chillers
- Residential split air conditioners, heat pumps and commercial refrigeration using high-pressure refrigerant
- Motor vehicle air conditioners
- Household refrigerators with 5 lb or less
Show the answer
B. Residential split air conditioners, heat pumps and commercial refrigeration using high-pressure refrigerant — Type II covers high- and very high-pressure appliances except small appliances and MVACs.
Question 4
How is a 'very high-pressure appliance' defined?
- An appliance using a refrigerant with a boiling point below -58 °F at atmospheric pressure
- An appliance using R-22
- An appliance operating above 500 psig
- An appliance with a water-cooled condenser
Show the answer
A. An appliance using a refrigerant with a boiling point below -58 °F at atmospheric pressure — R-13, R-23 and R-503 are very high-pressure refrigerants.
Question 5
Which refrigerant is used in very high-pressure appliances?
- R-22
- R-123
- R-503
- R-134a
Show the answer
C. R-503 — Very high-pressure refrigerants are used in low-temperature applications.
