INTRODUCTION: Wright Laboratories is interested in receiving proposals (technical and cost) on the research effort described below. No formal solicitation will be issued for this announcement, contractors are to submit proposals in accordance with the instruction that follow. Proposals in response to this Program Research and Development Announcement (PRDA) shall be submitted by 30 Jun 95, 2:00 P.M. Central time, addressed to 325 CONS/LGCX, 501 Illinois Ave, Suite 5, Tyndall AFB, FL 32403-5526, ATTN: AL ZIEMBA. This is an unrestricted solicitation. Proposals submitted after the cutoff date specified herein will be handled in accordance with the restrictions of FAR 52.215-10. B--REQUIREMENTS: (1) Technical Description: The purpose of this effort is to develop, design, fabricate, and test an environmentally benign, high efficiency 12KBtu prototype heat pump for use in rapid deployment, bare base operations. Environmental control units (ECUs) currently fielded provide the Air Force 60KBtu of heating and cooling for portable shelters of varying size and function. The 12KBtu prototype will begin the first of a three phase R & D effort that will ultimately lead to the replacement of existing Air Force compression units using R-22/R-134a with an advanced cycle 60KBtu ECU that will operate without the use of fluorocarbon refrigerants through reduced unit weight and space. The prototype should incorporate the features of compactness, lightness, high efficiency, durability, reliability, maintainability, low noise, and minimum heat signature. These units must be free of working fluids and refrigerants which would contribute to ozone layer depletion, global warming, or any other environmentally or occupationally hazardous condition. (2) Prototype Component Evaluation and Design: A component evaluation and design for a 12 KBtu prototype heat pump shall be conducted and shall include technical basis that the concept will conform to the following operational requirements: (a) Climate: An advanced cycle 12KBtu prototype shall be tested in accordance with ASHRAE 37-1988 for performance efficiency within a 47F - 95F temperature range simulating typical winter and summer conditions. The advanced cycle 12KBtu prototype shall be operational under all varieties and combinations of adverse weather conditions such as high and low humidity, precipitation, and temperature (25F - 125F). (b) Power Requirements: An advanced cycle 12 KBtu prototype shall be able to operate from nominal 3-phase commercial power at 50/60 Hertz 220/380 VAC. Prototype power optimization requirements in terms of life-cycle cost, load conditions, equipment capacity, operational impacts, and compatability are required. (c) Heating and Cooling Capacity: An advanced cycle 12KBtu prototype shall be capable of moving 12KBtu of heat within a 47F - 95F temperature range simulating typical winter and summer conditions. A coefficient of performance (COP) within this range shall not fall below 3. (d) Chemical/Biological Capabilities: An advanced cycle 12KBtu prototype shall be capable of being sealed against chemical/biological agents. The advanced ECU must be designed so that any part of the ECU that is part of the conditioned airflow circuit shall be at a positive pressure with respect to ambient. In addition, no part of the advanced ECU that is accessible to ambient air shall be at a positive pressure with respect to any part of the ECU which contains conditioned air. (c) Resistance to Deterioration: All components of the advanced cycle 12KBtu prototype shall be inert against potential agents such as gasoline, JP-8, engine oil, hydraulic fluid, ammonia, and paint thinner, as well as various chemical/biological agents. The prototype design shall include detailed system flow diagrams, detailed descriptions of component characteristics, operation, heat transfer thermodynamics, weight, and size. Calculations, computer modeling, component testing, and graphs shall be used to further support the feasibility of the prototype design. (3) Prototype Fabrication and Testing: A 12KBtu prototype heat pump shall be fabricated and tested according to ASHRAE 37-1988. The unit will be tested at 47F to establish the unit base COP for winter peformance and at 95F to establish the unit base COP for summer performance. As a minimum, the following items shall be addressed: (a) input and output temperatures of the heat transfer fluid/medium, Temperature differential; (b) flow rate of heat transfer fluid/medium; (c) power (kw) consumption per heating and cooling load conditions (d) heat load on compressor (if any). Results of analytical studies and testing shall demonstrate that the prototype design and hardware meet operational performance requirements over a range of heating and cooling capacities as specified. (4) Prototype Optimization: A 12KBtu prototype heat pump shall be optimized and test results validated to maximize the protype efficiency and capacity, and to minimize prototype volume, weight, and support logistics. (5) Deliverable Items: The following deliverable data items shall be proposed. (a) DI-MGMT-08227/T, Contractor's Progress, Status, and Management Report (Mthly); (b) DI-FNCL-8033I/T, Funds and Man-hour Expenditure Report (Mthly); (c) DI-F-6004B/T, Contract Funds Status Report (Qtrly); (d) DI-A-3024A, Presentation Material (As Req); (e) DI-MISC-80711, Scientific and Technical Reports - Draft and Reproducible Copy (interim and EOC); (f) advanced cycle 12KBtu prototype unit C -- ADDITIONAL INFORMATION: (1) Anticipated Period of Performance: The total length of the technical effort is estimated to be (24) months. The development, design, fabrication, and preliminary testing of the 12KBtu prototype will be conducted during the first 21 months of the effort at contractor facilities.
