    摘要: An exchanger for absorption or desorption of a refrigerant employs an ultra thin film (UTF) of a refrigerant solution constrained to a channel by a permeable membrane. The UTF has a thickness of about 250 μm or less. The permeable membrane can be a nanostructured membrane, such as a membrane of nanofibers. The exchangers can be employed in an absorption refrigeration system (ARS) that use waste heat or solar heaters permitting the ARS to be less than one tenth the volume and mass of a conventional ARS.

    摘要: A high efficiency heat sink for the cooling of microelectronic devices involves a phase change from liquid fluid to fluid vapor with a vapor quality of 100%. The liquid fluid is provided to an active area that contains fins having micrometer dimension that support a membrane that is nanoporous. The membrane is effectively impermeable to liquid fluid but permeable to fluid vapor. The heat sink provides very high heat flux and coefficient of heat transfer at low mass flux over a broad range of surface superheat temperatures. The heat sink can be constructed of equi-spaced posts that separate liquid microchannels from vapor microchannels that are connected through capillary forced valves formed between adjacent equi-spaced posts.

    摘要: An absorber for an absorption refrigeration system for a vertically mounted plate absorber has fins positioned over the plate to promote distribution of a fluid under flow as a nearly continuous thin film. The absorber has rows of fins that are evenly spaced with the fins occupying a portion of the active width of the plate with adjacent rows offset by the width of the plate. A combined evaporator-absorber module is constructed with the absorbing face of the absorber parallel with an evaporating surface of an evaporator where absorber solution and refrigerant fall as parallel falling sheets of liquid. The absorber is covered with a porous hydrophobic membrane to isolate the falling absorber solution from the falling liquid refrigerant.

    摘要: An absorption based heater is constructed on a fluid barrier heat exchanging plate such that it requires little space in a structure. The absorption based heater has a desorber, heat exchanger, and absorber sequentially placed on the fluid barrier heat exchanging plate. The vapor exchange faces of the desorber and the absorber are covered by a vapor permeable membrane that is permeable to a refrigerant vapor but impermeable to an absorbent. A process fluid flows on the side of the fluid barrier heat exchanging plate opposite the vapor exchange face through the absorber and subsequently through the heat exchanger. The absorption based heater can include a second plate with a condenser situated parallel to the fluid barrier heat exchanging plate and opposing the desorber for condensation of the refrigerant for additional heating of the process fluid.

    摘要: Various examples are provided related to dialysate-free renal replacement. In one example, a dialysate-free continuous renal replacement system includes a blood filtration stage (e.g., in a microfluidic membrane module). The blood filtration stage can include a blood filtration membrane configured to that can provide a filtered fluid by renal filtration of blood passing through the blood filtration stage at arterial pressure. The continuous renal replacement system can also include a salt recovery stage and a water recovery stage. The salt recovery stage can recover ions through separation from the blood filtration stage. The water recovery stage can separate water from the desalted fluid from the salt recovery stage, where the water is combined with the separated ions and reinfused into the blood after passing through the blood filtration stage.

    摘要: Various methods and systems are provided for electrokinetic dewatering of suspensions such as, e.g., phosphatic clay. In one example, among others, a system for continuous dewatering includes a cake formation zone including a first anode and a first cathode each extending across a first portion of a separation chamber; a cake dewatering zone including a second anode and a second cathode; an inlet configured to supply a dilute feed suspension comprising solids suspended in water to the cake formation zone; and a conveying belt extending between the first anode and the first cathode and between the second anode and the second cathode. A first electric field between the first anode and the first cathode forms a cake on the conveying belt by consolidating the solids, and a second electric field between the second anode and the second cathode dewaters the cake on the conveying belt.
