The high temperature NH3 enters the compressor at pressure
P1 at state 1 in which it is compressed to the pressure of P2,
with an isentropic efficiency,hc subsequently the compressed
fluid at state 2 is cooled in the Condenser to the temperature of
T3. The NH3 at state 3 enters the ejector nozzle and expands
with a nozzle efficiency ofhn.
