Rocky Research — Department of Defense SBIR Phase II: Proposed is the continuation of development of a High Efficiency Mobile Ice Maker (HEMIM)

Description

Proposed is the continuation of development of a High Efficiency Mobile Ice Maker (HEMIM) for the Army that is capable of integrating DC power from solar PV cells. The proposed ice maker will include a variable capacity vapor compression system with variable air flow as per ambient temperatures. The Performance of the high efficiency cycle will be enhanced by the use of advanced variable speed drive and pulsating thermal expansion valve technologies. The High Efficient Mobile Ice Maker (HEMIM) product will operate at all relevant military supplied DC and AC voltages while 30% or more efficient than exiting technology. The result will be a product that efficient, has more robust performance, smaller volume and lighter weight than competing technologies while attaining wide-ranging applicability. Phase I provided a very successful demonstration of an operational HEMIM. Phase II will focus on design refinement and optimization toward a 5,000 lbs of ice per day system, design to meet EMI and shock and vibration requirements, packaging the system so it can be attached to a Tricon insulated container , and delivery of two copies to the U. S. Army.
