ALREADY GRADED A+
Discharge vapor from all compressors - ANSWERS-will
contain some level of superheat
Which category of compressor " traps " a volume of
refrigerant vapor prior to compression ? - ANSWERS-Positive
displacement
When suction pressure rises , the operator should -
ANSWERS-start another compressor
