Want verification or correction of my theory and modelling of a direct expansion vapor compression refrigeration cycle that is combined with a liquid refrigerant pump. The pump increases the pressure of the liquid exiting the condenser to a pressure higher than discharge pressure and assists its flow to the expansion device in the vapor compression cycle. Additionally the pump injects the higher pressure liquid into the discharge line between the compressor discharge and condenser inlet for de-superheating of the discharge vapor. Therefore, additional fluid mass flows through the liquid receiver storage vessel, through the pump, into the discharge outlet conduit, through the condenser, through the liquid receiver storage vessel and back to the pump. I theorize that liquid injection de-superheating is an adjunct to the vapor compression system. Due to liquid injection de-superheating, more fluid mass flows through the condenser than flows through the remainder of the system. I also theorize that this system is a combination of a vapor compression system and a variation on the Organic Rankine cycle to account for liquid injection de-superheating heat transfer. I also theorize that liquid injection de-superheating changes the physical and thermodynamic characteristics of the fluid between the liquid injection site and the condenser outlet in such a way that more btu’s/hr are made available for heat rejection than were available from the vapor compression cycle alone. Modeling was done using Genetron Properties v1.2 (free for download from ) and Excel. They will be available to you. I am most concerned with verification or correction of my theory and method. I am less concerned at this point with the precise accuracy of calculations that may be due to rounding errors or due to specific suitability of the Genetron Organic Rankine model I have used.
