Rotary Vane Positive Displacement Air Cycle Machine for Army ECS Applications
Abstract
This report presents the results of laboratory tests and calculations conducted on a Model 606 air conditioning system designed for U. S. Army Mobile applications. The specified test conditions were as follows: an outside or sink temperature of 125 F, and inside or cooling load conditions of 90 F dry bulb and 67 F wet bulb. The results of performance testing a steady state cooling capacity of 7200 Btu/hr at a COP of 0.544 was measured during testing. This performance compares favorably with an overall COP on the order of 0.35 produced by well-developed conventional air cycle turbo-machine and air cycle system technology. Also included in this report are calculations predicting the performance of this Model 606 compressor-expander with ports designed to minimize port losses and internal thermal barriers to minimize adverse intra- Circulator heat transfer.
