SBIR 95-1 SOLICITATION
MICROWAVE REGENERABLE AIR PURIFICATION DEVICE
A more compact and thermally efficient technology is
proposed for the removal of CO2, H2O, and trace organic
contaminants from air during Extravehicular Activity (EVA).
Currently, expendable cartridges containing activated carbon
and lithium hydroxide are used for the removal of trace
contaminants, CO2, and water vapor inside the suit during
EVA. Systems anticipated for deployment during assembly of
the future International Space Station Alpha (ISSA) will use
metal oxide CO2 sorbents in conjunction with other thermally
regenerable media. Regeneration of these devices will
utilize conventional resistive heating elements and will
rely on conduction and convection of heat to the thermally
regenerable media. Significant improvements in size,
weight, power consumption, regeneration efficiency, and
regeneration times can be gained using dielectric heating.
Conventional techniques heat the system and then transfer
heat to the media. In the proposed innovation regenerable
media with suitable dielectric loss properties are heated
directly through microwave irradiation. This maximizes the
efficiency of energy transfer and minimizes conductive,
convective, and radiative losses as well as thermal mass.
Potential Commercial Applications:
The primary commercial application of the proposed
technology will be as flight hardware required by NASA to
support future long duration EVAs. It is anticipated that
the proposed technology will be integrated as a subcomponent
into the design of advanced Extravehicular Mobility Units.
