About expanders

Dear experts, I would like to ask: is there a significant difference between low-temperature compression and normal-temperature compression at the pressure-increasing end of an expander?
A booster and an expander are two distinct concepts; having them installed together is merely a mechanical combination. Its principle is to recover the mechanical energy transmitted by the spindle of the expander and direct it to the impeller, which then does work inside the volute; it is a turbine-type compressor used for pressurizing airflows. A turbine is driven by air flow, while a compressor compresses gas. Mechanical energy is used to drive the impeller to rotate at high speed, thereby compressing the gas. As for \"Is there a big difference between low-temperature supercharging and normal-temperature supercharging?\" ”I still don’t understand how the proposal works for this issue; my skill level is not high and my understanding is limited. Please explain it clearly so I can refer to it.
