    Abstract: A plate kind heat exchanger (1) has a plurality of stacked plates (2) forming flow paths for heat exchanging fluids there between, a first inlet channel being fluidly connected to inlets of a first set of flow paths, a second inlet channel being fluidly connected to inlets of a second set of flow paths, a first outlet channel being fluidly connected to outlets of the first set of flow paths, and a second outlet channel being fluidly connected to outlets of the second set of flow paths. The first inlet channel is provided with a stack (15) of rings (5) forming fluid passages towards the inlets of the first set of flow paths. Each ring (5) has a first rigid shell member (6) and a second rigid shell member (7), the first rigid shell member (6) and/or the second rigid shell member (7) defining a groove (9) providing fluid passage from the first inlet channel to one of the flow paths of the first set of flow paths, and a sealing member (8) formed from a compressible material, the sealing member (8) being positioned between the first rigid shell member (6) and the second rigid shell member (7). The stack of rings (15) is subjected to a force which presses the rings (5) towards each other and compresses the sealing members (8) of the rings (5), thereby providing sealing towards the flow paths of the second set of flow paths.

    Abstract: An active balancing valve for a refrigeration and/or air-conditioning application having a valve housing with an inlet orifice, an outlet orifice and a mounting portion, a main valve element with a main pressure balance orifice and a control element at least partially defining a pressure balance passage. Each element is slidable inside the valve housing and comprises a control surface for controlling a fluid flow between the inlet orifice and the outlet orifice. The control element closes the main pressure balance orifice of the main valve element in a closed state of the valve.

    Abstract: The present disclosure relates generally to a coupling assembly made up of a male fluid coupler and a female fluid coupler for a fluid line. The male and female fluid couplers are closed to flow in the uncoupled state and are open to flow when coupled. The male fluid coupler can include an alignment compensation arrangement that can adjust for any initial misalignment between the male and female fluid couplers. The alignment compensation arrangement can function as a universal connection joint to allow the male fluid coupler to universally pivot and move radially.

    Abstract: A method for controlling a vapour compression system (1) including a compressor unit (2) including at least two compressors (3, 12), a heat rejecting heat exchanger (4), a receiver (6), an expansion device (7) and an evaporator (8) arranged in a refrigerant path is disclosed. At least one of the compressors is a main compressor (3) being fluidly connected to an outlet of the evaporator (8) and at least one of the compressors is a receiver compressor (12) being fluidly connected to a gaseous outlet (10) of the receiver (6). A flow of vapour entering the receiver (6), such as a mass flow of vapour entering the receiver (6) is estimated and compared to a first threshold value. In the case that the estimated flow is above the first threshold value, a pressure prevailing inside the receiver (6) is controlled by operating the receiver compressor (12).

    Abstract: A pressure exchanger (1) including a housing (2), a drive shaft (3) and a cylinder drum (4) rotatably arranged in the housing (2) is described, the cylinder drum (4) including two front faces and at least one cylinder (5) between the front faces, wherein the housing (2) includes a port flange (7, 8) at each end of the cylinder drum (4) and at least at one end of the cylinder drum (4) a pressure shoe (18) is arranged between the cylinder drum (4) and the port flange of this end. Such a pressure exchanger should be operated in a cost-effective manner. To this end an adjustable stop arrangement (19) is arranged between the pressure shoe (18) and the cylinder drum (4).
