Distributed System Level Thermal Management of High Transient Heat Loads using Microchannel Evaporators

Abstract

This effort will focus on three primary tasks:1. Development of Microchannel Evaporator-integrated Vapor Compression Cycle (VCC) - develop a microchannel evaporator integrating favorable design features such as inlet orifices and tapering manifolds to mitigate instability, maldistribution and enhance overall heat dissipation.2. Modeling and Dynamic Control of Multi-Microchannel Evaporator VCC - extend controls framework to include issues unique to microchannel evaporators, and test simulation results experimentally.3. Integrated Device and Systems Levels Control Methodology ~ implement a distributed predictive optimization method, Alternate Direction Method of Multipliers (ADMM), combined with model predictive control to allow independent local optimization of the mass flow rate and pressure and a centralized global optimization to ensure the requested mass flow rates and pressure can be met by adjusting the compressor, recuperator bypass, and accumulator heat.
