INEFFICIENCY POINT:
The expansion valve brings
the refrigerating liquid from
high pressure to low
pressure with no use of
available potential energy.

The gas produced in the
heat exchangers is
processed in the
turbocharger, which makes
a pre-compression of the
refrigerant and, thereby,
reduces the energy
requirements of the main
compressor.
