Lightweight and Efficient Cooling System for Special Reaction Teams
Agency / Branch:
DOD / NAVY
Clothing that protects Special Reaction Teams from chemical, biological, and nuclear threats can subject the individuals to heat stress. These hazardous environments require the use of PPE with level A protection for several hours, which can diminish the body's ability to reject heat, leading to symptoms ranging from muscular weakness, dizziness and physical discomfort to more severe, life-threatening conditions such as heat exhaustion or heat stroke. RTI proposes to develop a miniature refrigeration unit, which utilizes a vapor compression cycle with the key component of an innovative rotary compressor, to remove heat from the user. This project will provide a portable cooling unit with a combination of performance, reliability, size and weight that is currently not possible from conventional designs. Specifically, the proposed cooling system will produce 125W of cooling to a water vest with a water temperature of 22 degrees C, weigh 3.5 lb (without battery), have a target volume of 1.0L and require 35W of electrical power. The Phase I effort will concentrate on the thermodynamic cycle, a novel condenser design, composite material implementation, thin film solid lubrication applications, and fabrication of a prototype compressor. The design of the remaining system, testing and integration would be performed in Phase II.
