Compact and Efficient Cooling Coils for Naval Systems Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-074 Topic Title: Compact and Efficient Cooling Coils for Naval Systems Proposal No.: N091-074-1374 Firm: Altex Technologies Corporation 244 Sobrante Way Sunnyvale, California 94086 Contact: John Kelly Phone: (408) 328-8302 Web Site: http://www.altextech.com Abstract: More compact and efficient cooling coils are needed to address increased heat management loads on Navy systems. Altex has identified an advanced cooling coil approach that can achieve the needed cooling, at half the typical cooling water flow, at face velocities exceeding 1000 fpm, without condensate carryover. Preliminary tests have shown the heat transfer potential of the concept. Under the proposed Phase I project, the concept will be adapted to the Navy cooling coil application of interest; and the performance and cost benefits of the concept will be determined, versus alternative techniques. In support of this assessment effort, a test article will be built and tested. These efforts will show the feasibility of the concept for cooling coil applications of interest. Benefits: By implementing the special cooling coil concept, Navy cooling coil heat transfer requirements will be met with half the typical cooling water flow at face velocities over 1000 fpm. Furthermore, this will be achieved at volume, weight and cost reductions of 40%, 50% and 35%, respectively. Importantly, the concept could be beneficially applied to other military, as well as civilian heat exchanger applications. Specifically, if the concept was applied to household heating and air conditioning applications, electricity cost, energy and CO2 savings would be $7.7 billion, 0.26 Quads and 70 million tons per year.
