A -- DEVELOPMENT OF AN EXPERIMENTAL CARBON-DIOXIDE-BASED HEAT PUMP -- BREADBOARD MODEL SOL DAAB15-99-Q-0017 DUE 060799 POC Point of Contact -- Jennifer L. Augustine, Contract Specialist, (703) 325-3355. Ana M. Kimberly, Contracting Officer, (703) 325-5800. WEB: CECOM Acquisition Center -- Washington, http://www.acbop.monmouth.army.mil. E-MAIL: Jennifer Augustine, CECOM Acquisition Center -- Washington, jaugus@hoffman-issaa2.army.mil. The US Army Communications Electronics Command (CECOM), Command and Control Directorate (C2D), Environmental Systems Branch, intends to award one or more purchase orders for the development of a laboratory working model of a transcritical CO2 cycle heat pump that would replace its current 36,000 BTUH capacity environmental control unit. The US Army 36K ECU is a packaged-unitary stationary-type unit which contains all system components in a single package and relies on external electric power. This effort is expected to produce a proof-of-principle prototype that demonstrates expected performance under a range of climatic conditions. (1) Offerors are expected to design, construct, and test an experimental CO2 system that utilizes the best available state-of-the-art CO2 prototype component technologies. It is essential that components to be designed and/or selected reflect maximum potential for system efficiency (COP) in the cooling mode, with secondary importance on minimizing overall system volume and weight, followed by system performance in heating mode. (2) Offers shall detail the tasks to be accomplished to complete the effort, to include all required tasks necessary for design, fabrication, instrumentation, data acquisition, analysis, reporting, followed by publication in an appropriate scientific forum. To the extent possible, offers should provide technical descriptions of the components to be utilized and address the extent to which the offer's technical approach represents a unique and innovative approach. (3) Where applicable, the Offeror should identify agreements and associations with supporting organizations which may be critical to successful and timely project execution. Offerors shall also address any proprietary elements contained in the proposal and any limitations, if any, to be imposed on the Army for later use of the research results. (4) The research plan shall include an appropriate set of heating and cooling test conditions and procedures that are to be based on the applicable ASHRAE Standard for such systems. Offers shall identify the laboratory and test facilities to be used, including methods of instrumentation and diagnostics; key personnel, their qualifications, and how their time shall be used; and a statement of the offeror's relevant organizational experience with CO2 cooling systems. (5) A detailed schedule of activities shall be provided including task durations and completion dates. (6) A cost proposal shall be provided which, as a minimum, shall identify direct labor expenses, equipment and supplies, purchased services, other direct costs including travel expenses, applicable overheads and fee, if any. The overall period of performance for all work shall not exceed one year from date of contract award, however, projects of shorter duration are preferred. To the extent necessary to support the proposal, offers may include illustrations of system schematics, components, facilities, tables of test criteria, and any other appropriate documentation. Detailed descriptions of proposed follow-on phases of effort are not desired. Offers shall not exceed 20 total pages. Offers shall remain valid until 31 December 1999. The Government reserves the right to make one or multiple awards to offerors with demonstrably unique and innovative technical approaches that fall within Government cost constraints. The resultant purchase order(s) will be firm-fixed price. Responses are to be received via email within 30 calendar days of the posting date of this notice. All requests for further information must be in writing or via email, telephone requests for additional information will not be honored. Forward responses to the following email address: jaugus@hoffman-issaa2.army.mil. Acknowledgment of receipt will be issued. Posted 05/07/99 (W-SN329140). (0127)
