Abstract : A heat-powered environment control unit (ECU) is a system that uses energy in the form of heat to produce thermal conditioning of a fluid to be used for environmental control purposes. It is envisioned that the energy source for the heat-powered ECU will be the normally wasted heat contained in the exhaust gases of standard Army gas turbine generator sets. The results of the studies conducted are presented in Section 2 through 4. An investigation of various thermodynamic cycles which could be utilized in this application is presented in Section 2. Thermodynamic optimization of the heat-powered ECU is presented in Section 3; this section also includes selection of the basic thermodynamic cycle felt to be most suitable, selection of the working fluid, optimization of the operating cycle, and a discussion of refinements for the selected basic cycle which can be utilized to increase the thermodynamic efficiency. Section 4 presents discussions on optimizing the various hardware design approaches. The recommendations for the heat-powered environmental control unit, as determined by this study, are summarized.
