Improved Stirling Cycle Technology for Zero-G
Spacecraft Refrigeration SystemsDean Applied
Technology Company, Inc.Huntsville, AL
Innovation This innovation improved the Stirling
refrigeration technology using a simple pulse
tube, and optimized the new configuration for
operation at food refrigerator/freezer operating
temperatures.
  • Accomplishments
  • Operational unit designed, fabricated and tested.
  • This concept offers a higher system efficiency
    than achieved by the currently used
    vapor-compression cycle in zero-g. It also
    eliminates the lubrication problems normally
    associated with zero-g refrigeration.
  • The improved Stirling Cycle technology does not
    require ozone-depleting Chloro-Fluoro-Carbons.
  • Since it has no moving parts at the cold end,
    vibrations are significantly reduced.
  • Commercialization
  • NASA Space Act Cooperative Agreement between
    NASA-Marshall Space Flight Center and Dean
    Applied Technology
  • Dean Applied Technology has applied for a patent.
  • Discussion with manufacturer of superconducting
    telecommunications equipment.
  • Inquiry from a major manufacturer of detector
    instrumentation equipment.

Pulse tube refrigeration unit under test at DATCO.
  • Government/Science Applications
  • Home refrigerator/freezers
  • Medical imaging (e.g., MRI)
  • Medical freezers
  • Cooling of electronics and detectors
  • Cooling of superconductors
  • Spacecraft freezer/refrigerators for Space
    Shuttle, Space Lab, ISSA, and Mars Missions
