Fig. 4 also shows that the evaporator mass flow rate of
the TPERC increases with increasing heat sink temperature.
The increase of the evaporator mass flow rate of the TPERC
leads to an increase in the heat transfer coefficient. However,
this also results in an increase of pressure drop across the
evaporator, leading to an increase in the specific work of the
compressor.
