Purpose amp Objectives Impact of Project 1 High-performance CCHPs result in significant savings (gt 60 compared to

electric resistance heating) result in an annual primary energy savings of 01 quads when fully deployed equivalent to 59 million tons of annual CO2 emissions reduction ndash Long Term

2 Analytical tools development to facilitate best practice of CRADA partners ndash Near Term

3 Project outcomes (single-stage) transferred to US OEMs by Emerson Climate Technologies ndash Mid Term

Technical goals (project outputs) Develop a 3-ton CCHP to minimize resistance heating

bull COP47degF gt 40 HP capacity-13degF gt 75 vs rated capacity47degF bull Maximize COPs at 17degF and -13degF with acceptable payback period

Progress and Accomplishments Market Assessment Concept Design Lab Prototyping Optimization Field Verification

Accomplishments ndash Lab prototype with tandem + EXV developed and verified ndash Established test rig to test multiple configurations ndash Achieved capacity goals ie gt75 at -13oF (77) GoNo Go

Milestone 2014 ndash Achieved COP goal gt40 at 47oF (41)

Progress on Goals ndash Emerson Climate Technologies to optimize a compressor design for

heating at low ambient temps (6 higher COP at low ambient temperatures)

ndash ORNL to test a tandem of vapor injection compressors ndash Evaluate ejector cycle over an extensive operation range

Market Impact Emerson Climate Technologies to provide compressor and system solutions to US OEMs in the next three years
