摘要： PCT No. PCT/SE96/01339 Sec. 371 Date Apr. 23, 1998 Sec. 102(e) Date Apr. 23, 1998 PCT Filed Oct. 21, 1996 PCT Pub. No. WO97/15798 PCT Pub. Date May 1, 1997A plate heat exchanger for two or more flowing media may according to the invention be designed so that the front and rear cover plates (1, 8) of the exchanger act as channel defining walls for a flowing heat exchanging medium, and so that the tube connections at the inlet and outlet ports (10-13) can be established in a common plane. This is obtained thereby that the front and rear cover plates (1, 8) together with the adjacent first (2) and last (5) channel forming plates define distribution channels (18) crossing the direction between adjacent inlet and outlet ports.

摘要： A brazed plate heat exchanger (10) comprising a stack of heat exchanger plates (12a, 12b) provided with a pattern comprising ridges (R) and grooves (G) to form plate interspaces (13a, 13b) for fluids to exchange heat. The heat exchanger plates are provided with port openings (01-04) forming axially extending inlet and outlet channels (14) for the first and second fluids, wherein at least one of the first and second heat exchanger plates is arranged with a skirt to form a chamber (17) between the port opening and the plate interspaces. The chamber (17) is open to the channel (14) through a gap between at least a free end portion of the skirt and the adjacent heat exchanger plate, and the gap varies around the circumference of the channel (14) and/or a cross section area of the chamber (17) varies around the circumference of the channel (14).

摘要： A brazed plate heat exchanger (10) comprises an end plate (11) and a stack of heat exchanger plates (12, 12a, 12b) provided with a pattern comprising ridges (R) and grooves (G) adapted to form contact points (16) between neighbouring heat exchanger plates such that the heat exchanger plates form interplate flow channels for media to exchange heat over the heat exchanger plates, the heat exchanger plates further being provided with port openings (01-04) for selective fluid communication with the flow channels, wherein the port openings are surrounded by port opening areas (13) for sealing against a corresponding port opening area of a neighbouring heat exchanger plate, wherein neighbouring heat exchanger plates are connected by brazing joints at said contact points (16), wherein the end plate (11) is provided with port openings (01-04) and flat areas (14) around the port openings in a common plane, wherein a plurality of ridges (R) of the heat exchanger plates, in an area overlapping any of said flat areas (14) of the end plate (11), are formed with an indentation (15), wherein said indentations (15) of a heat exchanger plate (12, 12a) adjacent the end plate (11) connect a flow channel, formed between the end plate and the adjacent heat exchanger plate (12, 12a), with a neighbouring flow channel to allow distribution of media between them. A brazing joint for connecting neighbouring heat exchanger plates is arranged between the port opening area (13) and at least one of said indentations (15).

摘要： A brazed plate heat exchanger (100) comprising 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. Further, the first heat exchanger plates (110) are formed with a first pattern having a first chevron angle (β1) and the second heat exchanger plates (120) are formed with a second pattern having a second chevron angle (β2) different from the first chevron angle (β1). Disclosed is also a refrigeration system and method including such as heat exchanger.

摘要： A refrigeration system comprises 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. A balance valve is arranged to enable bypassing the high temperature liquid refrigerant such that it does not exchange heat with the low temperature gaseous refrigerant from the condenser in the suction gas heat exchanger. Disclosed is also a method for controlling such a system.
