Figs. 7 and 8 present the variations of the compressor
pressure ratio and the discharge temperature with the heat
source temperatures, respectively. It can be clearly seen
from Fig. 7 that the pressure ratio of the TPERC is lower
than that of the CRC at the same heat sink temperature.
Considering Fig. 8, at a specific heat sink temperature, the
discharge temperature of the TPERC slightly decreases
while the heat source temperature increases. At the same
heat source temperature, the discharge temperature at higher
heat sink temperature is higher than at lower heat sink
temperature across the range of heat source temperatures.
The experimental results obtained from the CRC show a
