Open to participation for both US and overseas manufacturers, AHRI’s ‘Low GWP Alternative Refrigerants Evaluation Program’ will assess promising low-GWP refrigerants, including natural refrigerants, for different applications.
The industry-wide cooperative research programme was announced on 23 March 2011 by the US based Air-Conditioning, Heating, and Refrigeration Institute (AHRI). The programme aims at accelerating the industry's response to environmental challenges, by facilitating the selection of the most promising low Global Warming Potential (GWP) refrigerants and identifying technical challenges and research needs.
The programme will be headed by AHRI’s Vice President of Regulatory Policy and Research Karim Amrane, with laboratory testing expected to begin in July 2011.
Between now and July 2011, there will be a solicitation open to both US and foreign manufacturers to participate in the programme.
The product groups
Low GWP refrigerants, including natural refrigerants such as CO2, will be considered for application in the following major product categories:
Testing at laboratories of participating companies and universities
Most types of testing will be carried out at the laboratories of participating companies and will encompass:
Compressor calorimeter testing
System drop-in testing
Soft-optimised system testing
Moreover, the programme will include heat transfer coefficient measurements performed by universities and private research laboratories.
Project management and participation
The research programme will be managed by a technical committee, which will be responsible for developing detailed test protocols and quality control of the results. The technical committee will report to the AHRI Executive Committee.
After the technical committee has been established, US and foreign manufacturers will be solicited to participate in the testing programme, with actual testing expected to start in July 2011.
