Sorption refrigeration development at JPL/NASA.

Author(s) : JONES J. A.

Summary

In all, the Jet Propulsion Laboratory (JPL) has fabricated and successfully tested the following sorption refrigerators: physical solid adsorption systems (helium, nitrogen, krypton, R22, R134a, and ammonia), chemical solid absorption systems (hydrogen, nitrogen, and oxygen), and liquid absorption systems (ammonia and R134a). Two hydrogen chemisorption systems for cooling to -263 and -248 deg C are presently flight qualified and ready to cool detectors for a NASA Shuttle mission and a National Science Foundation (NSF) Balloon Flight. Two commercial projects are under development: a 7.2-ton solid adsorption air conditioner that will be installed on a subway train in Los Angeles, and a compact liquid absorption system that can be powered by gas heat or automotive exhaust waste heat, extremely simple, inexpensive, light weight, and insensitive to gravity vector changes.
