  • Patent number: 10247456
    Abstract: A receiver for a refrigeration system includes an enclosure with an inlet for liquid refrigerant at a first end and an outlet for the liquid refrigerant at a second end. A heat exchanger with an inlet and an outlet for refrigerant vapor is surrounded by the enclosure. The heat exchanger includes baffles so that alternatingly positioned flow passages are positioned on opposing sides of the enclosure.
    Type: Grant

  • Patent number: 9062900
    Abstract: A space-saving cooling system for an aircraft may include an evaporator in an enclosure with an accumulation region in the enclosure for a liquid mixture of liquid refrigerant and lubricating oil. Space saving may be achieved through a combining of evaporator functions and accumulator functions in a single enclosure. A heat exchanger may be interposed between the evaporator and the compressor for heating refrigerant emerging from the evaporator so that liquid refrigerant does not reach an inlet of the compressor.

  • Patent number: 8596089
    Abstract: A refrigerant distribution system has a plurality of chambers formed inside a refrigerant distribution plate, each of the plurality of chambers extending from one end of the refrigerant distribution plate into the refrigerant distribution plate; and a plurality of holes formed in each of the plurality of chambers, the plurality of holes fluidly communicating each of the plurality of chambers with an outside of the refrigerant distribution place. The evaporator may be oriented such that the refrigerant flows horizontally with respect to gravity. The present invention may improve the thermal performance of the evaporator while the evaporator is oriented sub-optimally. Often, with horizontal flow through an evaporator, the refrigerant phases, liquid and vapor, may separate in the manifold, resulting in poor distribution of refrigerant in the evaporator core. The refrigerant distribution plate of the present invention evenly distributes the refrigerant in the core.

  • Publication number: 20120102989
    Abstract: A refrigeration system may be provided with a space-saving suction-line heat exchanger. The heat exchanger may be incorporated into a receiver. As heated liquid refrigerant enters and flows through the receiver, it may transfer heat into the heat exchanger. The heat exchanger may be connected to a suction line of the system so that refrigerant vapor and an oil-refrigerant mixture may be heated as it passes from an evaporator and into an inlet of a compressor.
