Using REFPROP, R-23 and R-134a are analyzed at various state points to determine the optimum operating points to reach -80[degrees]C (-112[degrees]F) for the ideal mixed refrigerant cycle design.
Following compression, the vapor mixture of R-23 and R-134a enters a water cooled condenser (state 2) and is condensed at constant pressure.
Because the water cooled separator removes only enough energy to condense all of the R-134a to a saturated liquid; the R-23 exits the separator as superheated vapor.
It is assumed that the R-23 exiting the heat exchanger at state 7 in Figure 4 is completely condensed to a saturated liquid state.
The model predicted that the evaporator would reach a temperature of -87[degrees]C (-124.6 [degrees]F) under these conditions, but assumed perfect separation of the R-23 and R-134a streams exiting the separator.
The analysis predicts that the refrigeration system can reach the target evaporator inlet temperature of -87 [degrees]C (-124.6 [degrees]F) using a mixture of 33.4% R-23 and 66.6% R-134a by mass.
