Pdf
1. What type of systems does Type I certification cover?
A) High-pressure systems
B) Small appliances
C) Chillers
D) Industrial process refrigeration
Rationale: Type I certification specifically covers small appliances containing five
pounds or less of refrigerant.
2. Which of the following is a common refrigerant used in small appliances?
A) Ammonia
B) R-134a
C) R-717
D) R-744
Rationale: R-134a is commonly used in small appliances, such as refrigerators
and freezers.
3. Before opening a system for service, you must:
A) Evacuate the system
, B) Recover the refrigerant
C) Charge the system with nitrogen
D) Measure ambient temperature
Rationale: EPA regulations require recovery of refrigerants before opening any
appliance to prevent ozone depletion.
4. What device is used to remove refrigerant from an appliance safely?
A) Vacuum pump
B) Refrigerant recovery unit
C) Manifold gauge set
D) Pressure relief valve
Rationale: Refrigerant recovery units safely remove refrigerant from appliances
for recycling or reclamation.
5. What is the maximum allowable leak rate for a Type I small appliance during
repair?
A) 50% per year
B) 35% per year
C) No specific limit
D) 15% per year
Rationale: EPA Type I appliances do not have a specific mandatory leak repair
threshold, unlike larger systems.
6. When using a recovery cylinder, you should:
A) Use one approved for the specific refrigerant
B) Use any empty cylinder
C) Only use cylinders overfilled for speed
D) Vent excess refrigerant
Rationale: Recovery cylinders must be approved for the specific refrigerant to
ensure safety and compliance.
7. Which of the following is considered a “small appliance”?
A) Large commercial AC
, B) Industrial chiller
C) Domestic refrigerator
D) Supermarket freezer
Rationale: Small appliances are self-contained and contain five pounds or less of
refrigerant.
8. Refrigerant recycling is different from reclamation because:
A) Recycling only cleans refrigerant for reuse without meeting AHRI
specifications
B) Reclamation meets AHRI specifications
C) Recycling increases refrigerant charge
D) Reclamation is illegal
Rationale: Recycling involves cleaning refrigerant for reuse but does not
necessarily meet AHRI purity standards; reclamation does.
9. Which tool is used to measure the pressure of refrigerants in a system?
A) Thermocouple
B) Flow meter
C) Manifold gauge set
D) Multimeter
Rationale: Manifold gauges allow technicians to read system pressures
accurately.
10.What must you do before connecting a recovery unit to a system?
A) Add refrigerant
B) Check the system pressure and ensure proper connections
C) Vent the system
D) Remove all oils
Rationale: Proper connections and system checks are essential to prevent leaks
and ensure safety.
11.How should you handle a refrigerant leak in a Type I appliance?
A) Ignore it
