I am Hosea, from Nanyang Technological University Singapore. I am looking to acquire an ejector that would be used in a refrigeration system project.A similar schematic is attached for reference. May I request for the relevant catalogue to facilitate my discussion with my supervisor.The Outlet pressure to the condenser should be around 18 bars and the inlet pressure from the evaporator is at about 7 bars.The cooling capacity is at 3.2KW , evaporator inlet os at 11.81 degree c.The refrigeration used is R407C.

This is for refrigeration systemWould you advise the Pressure required for the generator before entering the ejector and the heat input required by the generator?
