Abstract
Disclosed is a refrigerant processing unit (1) for evaporating a refrigerant. The refrigerant processing unit (1) comprises a recirculation container (2) and a refrigerant inlet (3) connected to the recirculation container (2) for leading liquid refrigerant into the recirculation container (2). The refrigerant processing unit (1) also comprises a flooded evaporator heat exchanger (4) arranged to heat the liquid refrigerant to generate a phase change of the refrigerant from a liquid phase to a gaseous phase and a standpipe (5) extending between a liquid refrigerant outlet (6) of the recirculation container (2) and an evaporator inlet (28) of the flooded evaporator heat exchanger (4). Further, the refrigerant processing unit (1) comprises a return pipe (7) arranged to guide gaseous refrigerant from the flooded evaporator heat exchanger (4) back into the recirculation container (2) and a superheater heat exchanger (8) located below the recirculation container (2), wherein the superheater heat exchanger (8) is arranged to heat the gaseous refrigerant to generate a superheated gaseous refrigerant. Furthermore, the refrigerant processing unit (1) comprises a guide pipe (9) arranged to gu…
