COMPLETE 110 QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS)
ALREADY GRADED A+ BRAND NEW!!
2 stroke oil - CORRECT ANSWER: 50:1 1pint to 6 Gallons
4 Positions of DCV - CORRECT ANSWER: Open, Closed, Tandem, Floating
Ability of purifier to separate depends on what - CORRECT ANSWER: Difference in
specific gravities between materials
AC compression - CORRECT ANSWER: takes place in the compressor vapor temp is
raised above the cooling medium
AC condensation - CORRECT ANSWER: Takes place in the condenser. Superheat is
removed from vapor, refregerant condenses giving latent heat to cooling medium. Liquid
