Lead Performer: Oak Ridge National Laboratory - Oak Ridge, TN
Partners:
-- Honeywell - Morristown, NJ
-- University of Maryland - College Park, MD
DOE Funding: $4,850,000
Cost Share: Provided by CRADA partner
Project Term: 10/1/2010 - 9/30/2016

Project Objective

To develop low Global Warming Potential (GWP) refrigerant solutions for the Heating, Air Conditioning and Refrigeration (HVAC&R) market through leadership in Life Cycle Climate Performance (LCCP) modeling, experimental evaluation, and field testing. The CRADA partner will develop next generation of low GWP refrigerants to be evaluated at ORNL. ORNL will evaluate systems and components to identify the potential benefit from these refrigerants. Current low-GWP alternatives may increase energy consumption, introduce safety risks, and require significant equipment modifications. Effective alternatives are required to achieve the Building Technologies Office’s goal of reducing service equipment energy consumption and carbon emissions by 50% compared to current best practices.

Project Impact

This project developed and validated an Open Source LCCP Design Tool available for public, along with a web-based version. Furthermore, best practice guidelines for supermarket low GWP refrigerant switch-over with a documented field study results will be developed. This would have significant potential in reducing the potent greenhouse gas emissions while maintaining or reducing energy consumption at the pre-retrofit levels.
