  • Method and system for air contamination analysis for free air cooled data centers
    Patent number: 9999160
    Abstract: Example embodiments of the present invention relate to a method, a system, and a computer program product for controlling conditions of an input air stream. The method includes detecting air quality conditions as environmental input variables of an input air stream and determining whether to take corrective action on the air quality conditions of the input air stream according to the environmental input variables. An output variable then may be controlled to affect the air quality conditions of the input air stream.

  • Magneto-caloric cooling system
    Patent number: 9631842
    Abstract: A magneto-caloric cooling system includes an energy absorption area configured to be positioned proximate a thermal energy producing device. At least one energy dissipation area is configured to be positioned proximate a thermal energy dissipation device. A thermal energy transfer device is configured to be cycled between the energy absorption area and the energy dissipation area. A magnetic field generation device is configured to produce a magnetic field proximate the energy dissipation area.
