Throttling loss in the expansion device, through which
the refrigerant is expanded from the condenser pressure to
the evaporator pressure, is one of the thermodynamic losses
in a conventional vapor compression refrigeration cycle.
This expansion results during the isenthalpic process in
which the kinetic energy developed as the refrigerant
pressure decrease is dissipated to the refrigerant as friction
heat. The isenthalpic process causes the larger amount of the
