  • Performance of a thermally activated cooling system and design of a microchannel heat recovery unit

    Creator:
    Seward, Ryan
    Abstract:
    The performance of a combined vapor-compression cycle/ORC is evaluated using waste-heat from a diesel generator. A flat plate microchannel heat exchanger is employed to provide energy exchange between the diesel exhaust stream and an oil loop, which provides energy to a boiler. This study finds an increased diesel duty corresponds...

  • Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

    Creator:
    Brannon, Samuel T.
    Abstract:
    High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

  • Integrated dual cycle energy recovery using thermoelectric conversion and an organic Rankine bottoming cycle

    Creator:
    Miller, Erik W.
    Abstract:
    Hot engine exhaust and industrial process exhaust represents a resource that is often rejected to the environment without further utilization. This resource is prevalent in the transportation and industrial process sectors, but stationary engine-generator systems also typically do not utilize this resource. Engine exhaust is considered high grade heat and...

  • Adhesive microlamination protocol for low-temperature microchannel arrays

    Creator:
    Paulraj, Prawin
    Abstract:
    A new adhesive bonding method is introduced for microlamination architectures, for producing low-temperature microchannel arrays in a wide variety of metals. Sheet metal embossing and chemical etching processes have been used to produce sealing bosses and flow features, resulting in approximately 50% fewer laminae over traditional methods. These lamina designs...

  • A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

    Creator:
    Kawula, Steven P.
    Abstract:
    Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...
