similar trend. However, at the same heat source and heat
sink temperature, the discharge temperature of the CRC is
higher than that of the TPERC. Due to the fact that the
evaporator pressure in the CRC is lower than that in the
TPERC (while the condenser pressure of both systems is
nearly the same), the pressure ratio and the discharge
temperature of the CRC are higher than those of the TPERC.
A lower pressure ratio and lower discharge temperature
enable the compressor to have better lubrication and a
longer lifespan.
