Front
How many questions are on the Universal exam?
Back
The exam has 25 Core questions and 25 questions for each of Types I, II, and III, for 100 questions total.
03
Front
What is the passing threshold for a closed-book exam?
Back
A closed-book exam requires a score of at least 70 percent to pass.
04
Front
How do recovery, recycling, and reclamation differ?
Back
Recovery removes refrigerant into an external container; recycling cleans it for reuse; reclamation reprocesses it to a specified purity standard and verifies it analytically.
05
Front
How can CFCs and HCFCs contribute to ozone depletion?
Back
CFCs and HCFCs contain chlorine. In the stratosphere, ultraviolet light frees chlorine that contributes to ozone depletion.
06
Front
What happens to refrigerant in the evaporator?
Back
In the evaporator, low-pressure liquid absorbs heat and boils into vapor.
07
Front
What gas should generally be used to pressure-test a system?
Back
Use dry nitrogen with a regulator and suitable pressure-relief protection; do not use oxygen or compressed air for this purpose.
08
Front
Which appliances does Type I cover?
Back
Type I covers small appliances, generally factory-charged, hermetically sealed appliances containing five pounds or less of refrigerant.
09
Front
Which equipment falls under Type II?
Back
Type II covers high- and very-high-pressure appliances, excluding small appliances and motor-vehicle air conditioners.
10
Front
Which equipment falls under Type III?
Back
Type III covers low-pressure appliances, especially large centrifugal chillers.
11
Front
What can excessive purge-unit operation indicate in a low-pressure chiller?
Back
Excessive purge-unit operation can indicate that air or other noncondensables are entering the system.
12
Front
Can a mail-in Type I exam count toward Universal certification?
Back
A Type I exam taken by mail cannot be used toward Universal certification; the Core exam must be proctored.
