Expander cycle

The expander cycle is a thermodynamic cycle that is primarily used in the context of expanding gases in heat engines or refrigeration cycles. It involves the process of expanding a gas typically from a high-pressure state to a low-pressure state, often for the purpose of converting heat energy into mechanical work or for refrigeration processes. The expander cycle generally consists of the following key phases: 1. **Isentropic Expansion**: The high-pressure gas expands isentropically (i.e.
