We'll discuss the refrigeration cycle using the cycle diagram below. Component #1 is the compressor. It takes refrigerant vapor in from the low pressure side of the circuit, and discharges it at a ...

The major challenges in CO2 refrigeration involve the relatively high working pressures. The supercritical portion of the transcritical cycle takes place above 1,067 psia. The phase diagram for CO2 is ...
