Abstract
A system for cooling a cabin air compressor (CAC) motor includes a water separator which extracts water from airflow through a turbine and/or a fuel cell, and a CAC motor including cooling channels connected to an inlet and an outlet. The inlet of the CAC motor receives water from the water separator. The steam at the outlet of the CAC motor can be repurposed for warming utilities in an aircraft cabin, or for de-icing or increasing enthalpy of the turbine. The cooling water flow can be directed to the CAC motor in response to a predicted temperature of the CAC motor exceeding a threshold. The predicted temperature can be generated by feeding inputs including CAC motor input power measured by a power sensor, differential pressure measured by a pressure sensor, and a temperature at an air cooling inlet measured by a temperature sensor to a processor which generates a map model.
