A comparison of the cycle performance for the two
modes of operation, TPERC and CRC, can be made by two
approaches. The first one is based on internal parameters,
i.e., evaporating and condensing temperatures. This method
requires the different modes to be compared at the same
evaporating and condensing temperatures. The second one
is based on external parameters such as the inlet temperature
and the flow rate of the heat transfer fluid (HTF) [9,10]. This
method allows each mode of operation to operate under the
same external conditions. In this paper, the comparison
between the TPERC and the CRC is based on the second
method. This method is selected because it is more likely in
real life [10]. Water is used as the heat transfer fluid. Hot
water acts as a heat source while cold water acts as a heat
sink of the system.
