An ideal gas
air compressor cycle (with clearance) on pV diagram can be represented by
processes.
One
adiabatic, two isobaric and one constant volume
Two adiabatic
and two isobaric
Two
adiabatic, one isobaric and one constant volume
One adiabatic
one isobaric and two constant volume
Two adiabatic
and two isobaric
Adiabatic compression in simple terms means that no heat is given to or taken from the cylinder walls of the compressor. Also all work done in compressing the air is stored in the compressed air itself. Thus this process takes maximum energy input as no heat loss takes place through the cylinder walls.
Process 1– 2
: Adiabatic compression
Process 2– 3
: Discharge at constant pressure
Process 3– 4
: Adiabatic expansion
Process 4– 1
: Suction at constant pressure
Hence, the
correct option is (B).
