摘要： A comb-like insert having a body and plurality of tapered fingers is installed with its fingers disposed within respective minichannels. The fingers and their respective minichannels are so sized as to restrict the channels and frictionally hold the insert in place in one dimension while providing for gaps in another dimension such that the flow of refrigerant is somewhat obstructed but allowed to pass through the gaps between the insert fingers and the minichannel walls and then expand as it passes along the tapered fingers to thereby provide a more homogenous mixture to the individual minichannels. A provision is also made to hold the insert in its installed position by way of internal structure within the inlet manifold. In one embodiment, an internal plate is provided for that purpose, and the plate has openings formed therein for the equalization of pressure on either side thereof.

摘要： A heat exchanger includes a plurality of flat, multi-channel heat exchange tubes extending between spaced headers. Each heat exchange tube has a plurality of flow channels extending longitudinally in parallel relationship from its inlet end to its outlet end. A plurality of connectors are positioned between the inlet header and the heat transfer tubes such that the connector inlet ends are in fluid flow communication with the header through a relatively small cross-sectional flow area openings and the connector outlet ends are adapted to receive the inlet end of a heat exchanger tube. The connector defines a fluid flow pathway from the relatively small cross-sectional flow area opening in the inlet end of the connector to an outlet opening in the outlet end of the connector that opens to the flow channels of the heat exchange tube received in the outlet end of the connector.

摘要： In a parallel flow heat exchanger having an inlet manifold connected to a plurality of parallel channels, the degree of insertion depth of the parallel channels into the inlet manifold is variable so as to adjust the impedance to the refrigerant flow into the individual channels. The degree of insertion depth is progressively reduced toward a downstream end of the manifold for the individual channels or for the channel sections. The diameter of the inlet manifold is locally increased or its cross-section area altered in order to accommodate the flow of refrigerant around the tube insertions. Similar technique is applied to the outlet manifold as well to further balance hydraulic resistances.

摘要： In a parallel flow heat exchanger, which is susceptible to having a non-uniform distribution of a two-phase refrigerant flow to the individual channels, the resultant differences in the refrigerant flow therethrough are compensated and counter-balanced by a corresponding difference in the external heat transfer rate for the respective channels. In one embodiment, these differences are accomplished by variable characteristics of extended heat transfer surface elements such as fin type, fin density, fin geometry and difference in construction materials, and in another embodiment, by varying the airflow distribution over the cross-section area of the heat exchanger.

摘要： In a parallel flow evaporator, the inlet manifold construction consists of alternating expansion and contraction chambers to promote homogeneous conditions of the refrigerant, as it flows longitudinally through the inlet manifold, as a result of partial evaporation (throttling) and mixing and jetting effects (due to velocity augmentation). In a preferred embodiment, the parallel channels are fluidly connected to the expansion chambers so as to receive a homogeneous refrigerant mixture therefrom. In one embodiment, the expansion and contraction chambers are progressively smaller in size toward a downstream end, so as to accommodate the diminishing refrigerant flow as it progresses longitudinally along the inlet manifold. In another embodiment, the outlet manifold also consists of a repetitive pattern of alternating expansion and contraction chambers, so as to balance the impedances of the inlet manifold. In still another embodiment, these chambers are progressively larger in size toward a downstream end of the outlet manifold. In yet another embodiment, the flow-mixing inserts are introduced into the contraction chambers to further promote homogeneous conditions within the manifold. As a result, maldistribution in the heat exchanger is avoided, resulting in system performance augmentation and compressor reliability enhancement.

摘要： A heat pump is provided with a method and control for eliminating flooded starts. In particular, the heat pump at start-up is operated for a short period of time in the opposite mode to that in which it had been operated before the previous shutdown. In this way, the compressor ingestion of liquid refrigerant is limited or completely eliminated. After a short period of time, the heat pump is moved back to the intended mode of operation. Additional features can be added to the control scheme to limit this type of operation at start-up only to certain ambient conditions or only to a prolonged period between shutdown and start-up.
