Higher-lift lower-cost absorption cycles. Phase 1, final report

Technical Report ·
OSTI ID:5617062

The purpose of the research was to determine if modified NaOH solutions could be used in absorption heat pumps (AHP) to provide higher heat-pumping lifts from low ambient temperatures than are now possible. The research consisted of performing screening experiments on a great number of modified alkali hydroxide solutions, in order to characterize and bound the properties of boiling-point elevation, solubility limit, and corrosivity as a function of composition. Two preferred compositions were selected for more-detailed characterization: the binary NaOH-KOH and the ternary NaOH-KOH-CsOH. Lifts as high as from 0 to 90C were shown to be possible, which will extend AHP applicability into several important new applications.
