AbstractAqwest LLC proposes to develop a phase change material (PCM)-based thermal energy storage (TES) to enable"rightsizing"of environmental control units (ECU) and improve overall efficiency through reduced peak loads, more stabilized ECU operation, and off-peak thermal energy storage. The Aqwest TES has a very simple construction and mode of operation while offering major savings in energy consumption. The Aqwest innovative TES concepts for ECU allow for effective thermal coupling between the ECU and the PCM, which translates to>10% in energy use savings. In particular, our innovative PCM packaging and heat spreading concepts we earlier developed for the DOD overcome the low thermal conductivity of PCM materials, thus enabling compact packaging.
