What is the movement of heat through space called? - answer--
Radiation
A refrigerant release heat when - answer--It condenses
Why is it desirable for refrigerant in the suction line to be slightly
superheated? - answer--To insure liquid refrigerant does not enter the
compressor
A 30 pound cylinder of reclaimed R-22 refrigerant has been stored over
night at 70 degrees F. What should be the approximate pressure in the
cylinder? - answer--121 psig
14.7 psia( pouds per square inch absolute) is - answer--Approximately 0
PSIG
What is the main fuction of an air condition condenser? - answer--To
remove heat from the refrigerant
, Refrigerant R-134a vapor enters the condenser at 124 psig, 100 degrees
F. It leaves the condenser at 80 degreesF. What will be the approximate
pressure? - answer--124 psig (the pressure should not change entering
or leaving the condenser)
Which of the following CANNOT be used as a low ambient temperature
control? - answer--Crankcase regulating valve
When testing the efficiency of a (10 seer are lower) air cooled
condenser, the refrigerant condensing temperature should be no more
than_______ higher than the entering air temperature - answer--
Approximately 30 degrees F
When testing the efficiency of a water cooled condenser, the refrigerant
condensing temperature should be no more _____ higher than the
leaving water temperature. - answer--10 degrees F
What does a temperature differential across a filter-drier indicate? -
answer--Restricted filter-drier
Which of the following symptoms would be indicative of an oil logged
evaporator? - answer--Reduce heat transfer through the walls of the coil
