Beschreibung
Zusammenfassung:	A brazed plate heat exchanger (100) includes a plurality of first and second heat exchanger plates (110, 120) having different patterns of ridges and grooves providing contact points between neighbouring plates under formation of interplate flow channels for fluids to exchange heat, said interplate flow channels being in selective fluid communication with first, second, third and fourth large port openings (O1, O2, O3, O4) and first and second small port openings (SO1, SO2) forming a suction gas heat exchanger together with a dividing surface (DW). The ridges (R1, R2a, R2b) and grooves (G1, G2a, G2b) are formed such that the interplate flow channels between different plate pairs have different volumes. Disclosed is also a refrigeration system and method including such as heat exchanger.
