Disclosed is a refrigerant processing unit () for evaporating a refrigerant. The refrigerant processing unit () comprises a recirculation container () and a refrigerant inlet () connected to the recirculation container () for leading liquid refrigerant into the recirculation container (). The refrigerant processing unit () also comprises a flooded evaporator heat exchanger () 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 () extending between a liquid refrigerant outlet () of the recirculation container () and an evaporator inlet () of the flooded evaporator heat exchanger (). Further, the refrigerant processing unit () comprises a return pipe () arranged to guide gaseous refrigerant from the flooded evaporator heat exchanger () back into the recirculation container () and a superheater heat exchanger () located below the recirculation container (), wherein the superheater heat exchanger () is arranged to heat the gaseous refrigerant to generate a superheated gaseous refrigerant. Furthermore, the refrigerant processing unit () comprises a guide pipe () arranged to guide gaseous refrigerant from the recirculation container () into the superheater heat exchanger (), and an outlet pipe () arranged to guide the superheated gaseous refrigerant out of the superheater heat exchanger () and thereby out of the refrigerant processing unit (), wherein the flooded evaporator heat exchanger () and the superheater heat exchanger () are formed as a single heat exchanger unit () located below the recirculation container (). A method for evaporating a refrigerant and use of a refrigerant processing unit () is also disclosed.
