NAICS Code: 541620 Mobile Air Conditioner R152a and Second-Generation R744 System Component Assessment Period of Performance >From Purchase Order Award through August 31, 2004. Background Mobile Air Conditioners (MACs) contribute substantially to global warming. Greenhouse gas emissions come from direct emissions of the refrigerant used and indirect CO2 emissions from the combustion of fuel to power the air conditioner. HFC-134a (R134a), the predominate refrigerant in automotive air conditioners since the phase-out of CFCs, is a potent greenhouse gas. The MAC industry and environmental agencies around the world are working to reduce both direct and indirect emissions from MACS. This collaborative effort is a major focus of the EPA's Mobile Air Conditioning Climate Protection Partnership (MACCPP). Alternative refrigerants CO2 (R744) and HFC-152a (R152a) are being considered by vehicle manufacturers and their air conditioning suppliers as a way to achieve corporate and partnership goals. These refrigerants not only have much lower global warming potentials, but they have the potential to achieve higher energy efficiency automotive air conditioning systems. There is a discrepancy between the theoretical potential of alternative refrigerant MACs and their actual performance in operation. Therefore, alternative refrigerant air conditioning systems need to be analyzed so that they can be improved and compared with other systems. Until now, considerable testing has only been done on HFC-134a, first generation Carbon Dioxide and Propane systems. However, it is now clear that a test program needs to be in place which focuses on the R152a system and "second generation" R744 systems. The tests will evaluate and assess the potential contribution of refrigerant and components to overall system cooling capacity and efficiency performance. Purpose and Objectives Under this Purchase Order the Contractor shall test R152a and R744 air conditioner systems according to the test procedures established by the SAE Alternate Refrigerant Cooperative Research Program (SAE ARCRP). Task Description and Deliverables The Contractor shall conduct a series of tests of AC system and refrigerants with the following components: two (2) compressors with at least one having an integrated oil separator, two (2) evaporators, two (2) condensers, one (1) internal heat exchanger, one (1) oil separator. For each system using a specified component, the Contractor shall coordinate the testing on standardized testing equipment. In addition, the Contractor shall analyze and report electronically to EPA's MACCPP. The Contractor shall produce a single comprehensive report detailing the SAE ARCRP testing procedures after systems, with all the components, have been tested. The Contractor shall deliver a copy of the final financial and procedural issues report to the EPA Project Officer upon completion of the project. Format of Written Deliverables The Contractor shall submit all reports and documents in electronic format to the EPA Project Officer. All reports/documents submitted must be in hard copy and in 3.5" disk. Direct transfer of files by e-mail is also acceptable. The document program used to create these reports must be Corel WordPerfect 8. Adobe Acrobat PDF files are also acceptable and preferable to WordPerfect files if the report or document is in final form for dissemination/distribution. Database files should be maintained in MS Access 2000.
