Abstract
A plate heat exchanger (500) includes a plurality of heat exchanger plates (510, 520, 530, 540) provided with a pressed pattern adapted to provide contact points keeping the heat exchanger plates on a distance from one another such that interplate flow channels are formed between said plates, said heat exchanger being provided with interplate flow 5 channels (510-520, 530-540) for a first medium exchanging heat with a second medium in interplate flow channels (520-530) and a third medium in interplate flow channels (540-510), wherein the interplate flow channels are in selective fluid communication with port openings (550, 560, 570, 580, 630, 620) for the first medium, the second medium and the third medium. The heat exchanger (500) comprises first and second integrated suction gas heat exchanger sections (ISGHX1, ISGHX2) provided in the vicinity of port openings (550, 560, 570, 580) for the second medium and third medium. Every other heat exchanger plate is formed with a pressed first pattern of ridges and grooves, and the other heat exchanger plates are formed with a pressed second pattern of ridges and grooves, wherein the first pattern of ridges and grooves is different from 15 the second pattern of ridges and grooves.
