| Abstract: |
The objective of this project is to prove the feasibility and develop the components of a system for cooling a diver in the Shallow Water Combat Submersible (SWCS). RINI Technologies, Inc. is developing a Free Diver (untethered) Heating System (FDHS) for NAVSEA through a Phase II SBIR and proposes to build a complementary cooling system to provide thermal protection for both cold and warm water diving in contaminated water. Both units are battery powered but can be plugged into a power source of the SWCS for extended (>8 hours) run time. Each of the units proposed will be 10" long, 3" diameter, and 1.2 L volume. The heating system, which will reach TRL-6 in August of 2009, provides 300W of heat via 35øC water to the tube suit in 10øC ambient ocean water while consuming only 111W of electrical power. The proposed cooling unit will provide 250W of cooling via 20øC water in 40øC ambient ocean water, consuming only 115W of electrical power. Through the use of these systems, the Navy can perform un-encumbered long duration dives in contaminated water at temperature extremes in the SWCS and allow for untethered diving. |
| Benefits: |
RINI's heating and cooling unit will benefit the Navy by allowing for dive times greater than 8 hours in the SWCS and SDV while maintaining a high level of diver mobility. In addition to use with the SWCS, the heating and cooling units can be used in untethered dives with a battery, allowing for complete freedom and extended dive times at temperature extremes. Commercial applications include non-military technical dives such as law enforcement and search and rescue teams that require heating in extremely cold water and cooling in contaminated water. |
