Compressor opera on
1) Start of compression
1) The cylinder is fi lled with low pressure gas.
2) Since pressure in the discharge chamber
is higher than in the cylinder, the dis-
charge valve is kept closed.
2) Suc on and compression
1) The pressure in the cylinder increases
gradually.
2) Refrigerant suc on begins on the suc-
on side of the cylinder.
3) The discharge valve remains closed.
3) Discharge
1) The pressure in the cylinder exceeds that
in the discharge chamber, and the dis-
charge valve opens.
2) On the suc on side, refrigerant suc on
con nues.
4) Comple on of compression
1) When compression is completed, all of
the refrigerant has been drawn from the
suc on chamber.
