How is placement of the compressor line determined when drawing a PH diagram of an operating system?
A) The compressor line starts where the evaporator line crosses the suction line temperature and follows the constant enthalpy lines up until it crosses the condenser line.
B) The compressor line starts where the condenser line crosses the suction line temperature and follows the constant entropy lines up until it crosses the evaporator line.
C) Measure the suction-line temperature entering the compressor. Find where the evaporator line crosses this suction line temperature in the superheated area.
D) The compressor line starts where the evaporator line crosses the suction line temperature and follows the constant quality lines up until it crosses the condenser line.
