| Capacities are based on 38°C condensing temperature isentropic compression plus 28°C, evaporator temperature as shown plus 14°C superheat suction gas. |
| The first and third legs are nearly isothermal, while the second and fourth legs are nearly isentropic. |
| Other inputs included the degree of superheat and subcooling, isentropic efficiency of the compressor etc. |
| But in this case all isentropic curves, if sufficiently prolonged, will enter the heterogeneous region. |
| The isentropic surface varies in height from place to place over the Earth, the variation being indicated on the isentropic chart by isobars, lines showing the pressure at which the isentropic surface is found. |
| Either you use the isentropic efficiency, which is the ratio of actual work to theoretical work for an expansion process and the opposite for a compression process. |
