SBIR 95-1 SOLICITATION
DEVELOPMENT OF A HIGH-LIFE COMPRESSOR FOR MODULAR HEAT PUMP SYSTEMS
Heat pumping can be useful in space applications, but proven,
effective, modular systems are not available. This proposal
argues that for the temperature range of interest (240K to
290K), vapor compression systems are the most attractive with
respect to weight, size, power consumption (COP), and
flexibility for use with proven lightweight heat exchangers
which can be modularly coupled to thermal transport systems. A
novel two-stage rotary compressor to provide a temperature lift
of 55K or better is proposed to be demonstrated. The
compressor uses a single refrigerant, is contained in a single
housing, and can be operated on mist lubrication without
reliance on an oil sump or gravity feed.
Cycle analysis will show that suitable refrigerants exist for
the desired temperature range, and that an efficient heat pump
cycle can be constructed using conservative estimates of system
losses. A refrigerant will be selected, and a prototype
compressor will be manufactured and demonstrated. Phase II
will continue life testing and develop a package for
demonstration in space, consistent with NASA's modular heat
Potential Commercial Applications:
The concept proposed here has many potential terrestrial
commercial applications, anywhere cooling is needed, and space
and weight are limited. Examples of these applications include:
Low temperature electronics cooling in large computer systems.
Microclimate cooling for very hot operations (desert, jungle, etc.).
Mobile and portable low temperature refrigeration systems.
The compressor design proposed here can be applied directly to these applications.
