摘要： A refrigeration system includes a compressor for compressing a gaseous refrigerant, such that the temperature and pressure thereof increases, whereas the boiling point thereof decreases; a condenser, in which the gaseous refrigerant from the compressor exchanges heat with a high temperature heat carrier, said heat exchange resulting in the refrigerant condensing; an expansion valve reducing the pressure of liquid refrigerant from the condenser, hence reducing the boiling point of the refrigerant; an evaporator, in which the low boiling point refrigerant exchanges heat with a low temperature heat carrier, such that the refrigerant vaporizes; and a suction gas heat exchanger exchanging heat between high temperature liquid refrigerant from the condenser and low temperature gaseous refrigerant from the evaporator. The low temperature gaseous refrigerant entering the suction gas heat exchanger contains a certain amount of low temperature liquid refrigerant, said low temperature liquid refrigerant vaporizing as a result of the heat exchange with the high temperature liquid refrigerant from the condenser. Disclosed is also a refrigeration method.

摘要： 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 guide gaseous refrigerant from the recirculation container (2) into the superheater heat exchanger (8), and an outlet pipe (10) arranged to guide the superheated gaseous refrigerant out of the superheater heat exchanger (8) and thereby out of the refrigerant processing unit (1), wherein the flooded evaporator heat exchanger (4) and the superheater heat exchanger (8) are formed as a single heat exchanger unit (11) located below the recirculation container (2).
