8: A near azeotropic blend will contain:
A. One saturation pressure value
B. One high saturation pressure value
C. Two saturation pressure values that are close

2

,D. Two saturation pressure values that have a big difference
-ANSWER- C
Rationale: A near azeotropic blend contains two saturation pressure values that are
close.
9: A zeotropic blend will contain:
A. One saturation pressure value
B. One high saturation pressure value
C. Two saturation pressure values that are close
D. Two saturation pressure values that have a big difference
-ANSWER- D
Rationale: A zeotropic blend contains two saturation pressure values that have a
big difference.
10: Access fittings:
A. Need to be leak tested before recovering refrigerant
B. Are used to gain access to closed systems
C. Are used with window AC units
D. All of these
-ANSWER- D
Rationale: Access fittings need to be leak tested before recovering refrigerant, are
used to gain access to closed systems, and are used with window AC units.
11: Defrost heaters in frost-free refrigerators can help with which of the following?
(Select all that apply)
A. Melt frost buildup on the evaporator coil
B. Increase refrigerant recovery speed by warming the system
C. Operate in all Type I appliances
D. Eliminate the need for refrigerant recovery equipment
-ANSWER- A, B
Rationale: Defrost heaters can melt frost buildup on the evaporator coil and
increase refrigerant recovery speed by warming the system.
12: If the compressor is not working and we are performing passive recovery, we
need to take steps to do what?
A. Recover at least 80% of charge indicated on appliance nameplate
B. Vacate the area
C. Ventilate the working space
D. Release trapped refrigerant from the compressor oil

3

, -ANSWER- A
Rationale: If the compressor is not working and we are performing passive
recovery, we need to recover at least 80% of charge indicated on appliance
nameplate.
13: If the pressure of the system is found to be 0 psig, can we recover refrigerant
from the system?
A. Yes
B. No
C. It depends on how much refrigerant is left
D. It depends on the type of refrigerant
-ANSWER- A
Rationale: Yes, refrigerant can still be recovered from a system with a pressure of
0 psig.
14: If the pressure reading and expected pressure are far apart, which of the
following are possibly contained in the refrigerant?
A. Air
B. Water vapor
C. Nitrogen
D. All of these
-ANSWER- D
Rationale: Air, water vapor, and nitrogen are all possible non-condensables that
could be contained in the refrigerant.
15: A sealed household refrigerator has a working compressor and a blocked
capillary tube. To recover the charge, what access setup is required?
A. One access valve on the high side only
B. Two access valves, one on each side
C. No access valves; pull through service port
D. One access valve on the low side only
-ANSWER- A
Rationale: One access valve on the high side only is required to recover the charge.
16: Solderless piercing valves:
