answers{verified answers}already graded A+
1. Which of the following is an example of a small appliance covered under
Type I certification?
A. Residential split system AC
B. Window air conditioner
C. Chiller system
D. Industrial refrigeration unit
Small appliances are typically self-contained units under 5 pounds of
refrigerant, like window ACs and domestic refrigerators.
2. What is the maximum charge of refrigerant allowed in a small appliance?
A. 10 lbs
B. 5 lbs
C. 5 lbs or less
D. 2 lbs
Small appliances are defined as containing 5 lbs or less of refrigerant.
3. What must a technician do before opening a small appliance system?
A. Replace the compressor
B. Recover all refrigerant
C. Evacuate the air only
D. Check the thermostat
Technicians must recover all refrigerant to prevent release into the
atmosphere.
4. What type of refrigerant is commonly found in small appliances today?
A. R-22
B. R-717
C. R-134a
D. R-410A
R-134a is widely used in small appliances due to its low ozone depletion
potential.
, 5. During refrigerant recovery, which of the following is true?
A. Refrigerant can be vented to the atmosphere
B. Refrigerant must be converted to liquid
C. Technicians must use EPA-approved recovery equipment
D. Only oil needs to be recovered
EPA regulations require using approved equipment to safely recover
refrigerants.
6. What is the first step in servicing a small appliance?
A. Evacuate the system
B. Identify the refrigerant type
C. Charge the system
D. Replace the filter
Identifying the refrigerant ensures proper handling and compliance with EPA
rules.
7. Which tool is required for leak detection on small appliances?
A. Screwdriver
B. Electronic leak detector
C. Pipe wrench
D. Manifold gauge only
Electronic leak detectors are recommended to safely identify refrigerant leaks.
8. Which of the following is true about reclaiming refrigerants?
A. It can be vented after use
B. It requires no certification
C. It must be processed to industry standards
D. It can be stored indefinitely without processing
Reclaimed refrigerants must meet AHRI 700 standards before reuse.
9. How should recovered refrigerant from small appliances be stored?
A. Open container in shop
B. In DOT-approved cylinders
C. Any plastic container
D. In oil-filled tanks
EPA requires using proper containers to prevent leaks and contamination.
, 10.What is the key difference between Type I and Type II certification?
A. Type I handles chillers
B. Type I handles small appliances only
C. Type I handles high-pressure systems
D. Type I is for industrial systems
Type I certification covers only small appliances under 5 lbs of refrigerant.
Type II: High-Pressure Refrigeration and Air Conditioning (Questions 11–25)
11.Type II certification allows technicians to service which systems?
A. Small appliances
B. High-pressure systems
C. Low-pressure chillers
D. All systems
Type II covers high-pressure systems above 5 lbs, like residential AC and heat
pumps.
12.Which refrigerant is considered high-pressure?
A. R-717
B. R-22
C. R-134a
D. R-123
R-22 is a high-pressure refrigerant commonly found in residential systems.
13.When connecting manifold gauges, which color is used for the low side?
A. Yellow
B. Green
C. Blue
D. Red
Blue gauges indicate the low-pressure side; red is for high-pressure.
14.Which tool is essential for evacuating a high-pressure system?
A. Pipe wrench
B. Refrigerant leak detector
C. Vacuum pump
D. Screwdriver
Vacuum pumps remove air and moisture before charging refrigerant.
