The Phase I was highly successful and included the design, building and testing of a 5-ton Hydrocarbon refrigerant ECU (HECU). The Coefficient of Performance in Cooling (COPc) of the HECU was demonstrated to be 6% better than an otherwise identical system using HFC-410A and 25% better than the FDECU (and 33% lighter than the FDECU). The Phase I demonstrated that the HECU is the most efficient and lightest ECU configuration available, while also being the only unit which will meet all the Global Warming restrictions of the Kyoto Protocol. The HECU meets ASHRAE Standard 15, EPA/SNAP and UL requirements for A3 refrigerants. This proposal discusses the results of Phase I and the proposed Phase II effort which will concentrate on extensive field-tests, production optimization, commercialization, detailed off-design performance testing, extended life testing, development of 24/7 interactive web-base support, and production scale-up. HECUs that have been extensively (field, life and performance) tested will be available for commercial sale at the conclusion of the Phase II effort. Our accelerated schedule not only reduces the risk to the government (since the HECU has already been demonstrated), it also allows commercialization to begin at the end of the Phase II effort.
