This Small Business Innovation Research (SBIR) Phase I project will build and operate a proof-of-concept unit of a thermally activated heat pump with a higher efficiency than the commercial LiBr absorption chiller. Such heat pumps, which can be used for both cooling and heating, are cheaper to build, easier to operate, has a smaller footprint, and are expected to last longer than the commercial LiBr chillers. They can be driven by low level heat from low cost solar collectors. The materials in the system are basically non-toxic. Currently, commercialization of the less efficient and more costly aqua-ammonia absorption heat pump for heating is being considered by DOE although such systems are not suitable for using heat as low as 70o C. The broader/commercial impacts of this research are reducing the fuel consumption for heating by more than 45% from the conventional furnaces, enabling utilization of heat from low cost solar collectors, engine cooling-water, or other low level heat as low as 70o C for air conditioning and/or heating with greater than 100% ?thermal efficiency?. Wide use of this technology can potentially save 5-10% of the energy used in this country and greatly reduce the summer electricity demand peaks.

这个小型企业创新研究（SBIR）第一阶段项目将建造和运行一个热激活热泵的概念验证单元，其效率高于商用溴化锂吸收式制冷机。这种热泵既可用于制冷又可用于制热，建造成本更低，操作更容易，占地面积更小，预计比商用溴化锂制冷机使用时间更长。它们可以由低成本太阳能集热器的低水平热量驱动。系统中的材料基本无毒。目前，能源部正在考虑将效率较低、成本较高的氨水吸收式热泵商业化，尽管这种系统不适合使用低至70 ° C的热量。 这项研究的更广泛/商业影响是减少燃料消耗加热超过45%，从传统的炉，使热量利用低成本的太阳能集热器，发动机冷却水，或其他低水平的热量低至70摄氏度的空调和/或加热大于100%？热效率？这项技术的广泛使用可以节省5-10%的能源使用在这个国家，大大减少夏季电力需求高峰。
