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.

Integrated receiver and suction line heat exchanger for refrigerant systems

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.

Integrated evaporator and accumulator for refrigerant systems

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.

Refrigerant distribution system

A rigid or semi-rigid demister pad is positioned between an air turbine and an inertial water removal device such as extractor in an air conditioning system for an aircraft. The demister pad comprises packed fibers or strands whose diameter typically ranges from approximately 10 or fewer microns to approximately 280 microns. The demister is capable of catching very small droplets discharged from the air turbine that coalesce into larger droplets that exit the demister pad and enter an adjacent water removal device downstream from the pad to separate the larger water droplets from the stream of air. This avoids using a water separator containing a coalescer bag that requires frequent maintenance and is sensitive to dirt and freezing. The demister can operate at freezing temperature, is not dirt-sensitive and requires no maintenance.

Water removal downstream of a turbine

A recirculating water extractor includes a swirl vane, a converging nozzle, and two sumps. The recirculating water extractor may be designed to reintroduce uncollected water droplets back into the air stream upstream of both sumps, which may provide additional opportunities for separation. The Coanda effect may be exploited to increase the discharge of water along a surface. Utilizing a converging nozzle may intensify the centrifugal force applied to the air stream rich with entrained water and may move more of entrained water into contact with the wall of the nozzle, which, in turn, may enhance the liquid/vapor separation compared to prior art water extractors. The recirculating water extractor utilizing the Coanda effect and the method for removing entrained water from an air stream may be suitable for, but not limited to, applications in the aircraft and aerospace industries, for example, by being included in environmental control systems of aircraft.
