Why two-stage compression is more energy-efficient than one-stage compression
According to the working principle of the compressor, isothermal
compression is the most power-saving. The following is the
indicator diagram of the compression process, curve 12'3' is the
isothermal compression process, and the area formed with the
ordinate 613"4 is the indication work of isothermal compression.
The curve 123" is the first-order compression process, and the area
formed with the ordinate 613"4 is the indicative work of
first-order compression. Curves 12, 22", 2'3 are the two-stage
compression process, and the sum of the area 6125 and 52'34 formed
by the ordinate (6122'34) is the indicative work of the two-stage
compression.
As can be seen from the following figure, the 613'4 area (indicated
work) of the isothermal compression process is the smallest, but
the isothermal compression cannot be achieved in the actual
compression process of the compressor, and the first-stage
compression has 13'3 "area power more than the isothermal
compression, while the two-stage compression saves 2'23"3 area
power than the first-stage compression.
