Beschreibung
Zusammenfassung:	A brazed plate heat exchanger (100) comprising a plurality of first and second heat exchanger plates (110, 120), wherein the first heat exchanger plates (110) are formed with a first pattern of ridges (Rl) and grooves (G1), and the second heat exchanger plates (120) are formed with a second pattern of ridges (R2a, R2b) and grooves (G2a, G2b) providing contact points between at least some crossing ridges and grooves of neighbouring plates under formation of interplate flow channels for fluids to exchange heat, said interplate flow channels being in selective fluid communication port openings (01, 02, 03, 04). The first pattern of ridges and grooves is different from the second pattern of ridges and grooves, so that an interplate flow channel volume on one side of the first heat exchanger plates (110) is different from the interplate flow channel volume on the opposite side of the first heat exchanger plates (110). The first pattern exhibits a first angle (β1) and the second pattern exhibits a second angle (β2) different from the first angle (β1), and the heat exchanger (100) is provided with a retrofit port heat exchanger (400). A system and a method are also disclosed.
