Veyo, S E

The advanced electric heat pump with dual-stroke compressor meets its performance objective by providing an estimated annual energy efficiency 20 percent better than the most efficient heat pump available at contract inception. The dual-stroke compressor, indoor blower, and outdoor fan can save sufficient energy relative to their commonly used alternatives so as to permit recovery of their premium first cost in less than four years operation. The dual-stroke mechanism for capacity modulation is low in cost and is, in all likelihood, the lowest cost alternative available. A procedure for optimizing heat pump system proportions based upon estimated annual performance and life-cycle cost has been developed. Additional testing, especially under field conditions, is necessary before commercialization can be expected.
