Second Stage Evaluation of Hy-Save LPA. Recommendation #472

by H.M. Curan, Ph.D, P.E.

"...shows that of every 100 inventions submitted for evaluation, about 2 are recommended to DOE."

"Our evaluation has been completed and we recommend Mr. Hyde's invention as technically valid and worthy of consideration for appropriate Government support."

"Three consultants reviewed this invention at the first-stage level. The invention was entered into second-stage evaluation on January 10, 1989. The second-stage review was conducted by Dr. H.M. Curran, a consulting engineer from St. Petersburg Beach, FL."

"The invention has been successfully tested at two supermarkets in western Oregon. The tests were monitored by Gregory Wheeler of Oregon State University and Gayland Smith of the Oregon Department of Energy."

"This invention will also save energy in air conditioning systems for commercial buildings since interior rooms need cooling throuhgout the year."

"There is no question that this invention has significant potential to save energy in commercial freezers and refrigerations with their condensers located outside the building."

"For each 2,000 such systems out of the thousands of potential sites that are equipped with this invention, the overall energy savings equivalent would be about 0.756 million barrels of oil per year."

"The invention also has the potential to save energy in commercial air conditioning systems. Assuming full market penetration the overall energy savings could be in the millions of barrels of oil per year on the national scale."

"Because this invention has the potential to lower peak electric demand for summer peaking utilities, the power companies have shown interest."

"This invention is technically sound..."

"Like other new products, there may be initial resistance from established equipment maufacturers"

"This invention is technically feasible and cost-effective."

"This invention is technically valid with respect to thermodynamic principles and physical implementation."
