Heat Actuated Cooling System

The principal objective of this effort is to develop an advanced complex compound for ammonia-solid absorption chillers and demonstrate the enhanced sorbent for a 18,000 BTU/hr technology demonstrator in the Phase II effort. Phase I experimental data showed that it is feasible to make a fuel-fired sorption cooling system capable of 18,000 Btu/hr cooling and 105 kg dry-weight with 0.34 gal/hr of JP-8 fuel consumption. Since low temperature exhaust of less than 150 degrees C (302 degrees F) can be harvested in this system, it is expected that fuel consumption will be less than 0.34 gal/hr. The goal of phase II will be to design, build, test and deliver prototypes with total weight of 105kg-dry and fuel consumption of less than 0.34 gal/hr of JP-8. A 3-D preliminary design of the overall prototype package has been completed. This design will be fabricated, tested and delivered to the ARMY during Phase II.
