    摘要： A refrigerant gas leak sensor for a HVAC system includes a housing, a gas sensor core element and mounting means. The housing has primary walls delimiting an inner volume. The gas sensor core element is arranged in the inner volume. The mounting means is configured to attach the housing to a mounting surface, wherein a first surface of a primary wall of the housing faces the mounting surface and wherein a gap is provided between the first surface and the mounting surface. An opening is formed in the housing for exposing the gas sensor core element to gases within the HVAC system, wherein the opening is provided on the first surface. The refrigerant gas leak sensor may be provided as part of an air handling unit.

    摘要： A heat exchanger and an air conditioning system having same, the heat exchanger including: a first manifold and a second manifold disposed at one and the same side of the heat exchanger; and multiple heat exchange tubes, each heat exchange tube including: two ends, the two ends respectively being a first end and a second end, the first end and second end being respectively connected to and in fluid communication with the first manifold and the second manifold; and multiple heat exchange parts, the multiple heat exchange parts including a first heat exchange part and a second heat exchange part, the first heat exchange part and second heat exchange part being respectively connected to and in fluid communication with the first end and the second end; in a lengthwise direction of the first manifold or second manifold, the ends of the multiple heat exchange tubes includes at least one pair of adjacently arranged first ends and/or at least one pair of adjacently arranged second ends. Heat exchange performance is thereby improved.

    摘要： 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.

    摘要： 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.

    摘要： 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.
