Thermodynamics question:
Is vapor injection on a refrigeration cycle equivalent to regeneration on a Rankine cycle?
They seem like they're doing the same basic thing, except you're subcooling refrigerant with gas that's then fed into the middle of the compression process, rather than preheating working fluid with gas taken from the middle of the turbine expansion process.
This whole heat pump business really forced me to brush up on stuff I forgot about years ago.
