  • Patent number: 11686510
    Abstract: A process is disclosed for cooling a material that includes semiconductor nanoparticles in matrix material by anti-Stokes up-conversion. The semiconductor nanoparticle matrix is irradiated by a laser with a photonic wavelength matched to the anti-Stokes photoluminescence of the semiconductor nanoparticle bandgap. The semiconductor nanoparticles absorb the laser photon and phonons (heat) from lattice vibrations to photoluminescence photons with higher energy than the photon that were absorbed. A net cooling effect is generated from the lower energy and lower temperature in the material after anti-Stoke up-conversion.

  • Patent number: 11686511
    Abstract: A method of cooling a motor coupled to a compressor of a chiller includes adjusting a position of a motor cooling valve located fluidly between the motor and a refrigerant source, using a motor temperature control system coupled to the motor cooling valve to regulate an amount of refrigerant introduced into the motor from the condenser according to a temperature control scheme performed as a function of a monitored temperature in the motor, a first temperature threshold, and a second temperature threshold lower than the first temperature threshold. The temperature control scheme includes a motor cooling control process that adjusts the position of the motor cooling valve based on a stator winding temperature set point relating to stator windings of the motor. A proportionally limited close command override associated with a first temperature range above the second temperature threshold proportionally limits a close command provided to the motor cooling valve.
