Title: Pump for mixed phase refrigerant
Agency: DOD
Contract: W31P4Q-13-C-0049
Award Amount: $700,000.00


Current refrigerant pumping technology lacks the ability to circulate a liquid-vapor mixture with substantial flow resistance, which impedes development and implementation of two-phase cooling technology. Common pump designs will hydro-lock and mechanically fail instantly or suffer performance loss and eventually fail due to cavitation or worn components. Mainstream Engineering Corporation has designed, fabricated, and tested a device that is capable of pumping R-134a refrigerant in saturated mixtures ranging from liquid to vapor, which will be refined and brought to TRL7 in Phase II. Refinement efforts will concentrate on increasing efficiency of the proven device. The performance enhanced pump will be production intent ready on a common platform for cross function commercialization.
