【 摘 要 】

Solar Fueled Products (SFP) is developing an innovative ionic-liquid absorption heat pump (ILAHP). The development of an ILAHP is extremely significant, as it could result in annual savings of more than 190 billion kW h of electrical energy and $19 billion. This absorption cooler uses about 75 percent less electricity than conventional cooling and heating units. The ILAHP also has significant environmental sustainability benefits, due to reduced CO2 emissions. Phase I established the feasibility and showed the economic viability of an ILAHP with these key accomplishments: ??? Used the breakthrough capabilities provided by ionic liquids which overcome the key difficulties of the common absorption coolers. ??? Showed that the theoretical thermodynamic performance of an ILAHP is similar to existing absorption-cooling systems. ??? Established that the half-effect absorption cycle reduces the peak generator temperature, improving collector efficiency and reducing collector area. ??? Component testing demonstrated that the most critical components, absorber and generator, operate well with conventional heat exchangers. ??? Showed the economic viability of an ILAHP. The significant energy savings, sustainability benefits, and economic viability are compelling reasons to continue the ILAHP development.
