Low-temperature thermal energy storage quarterly progress report for period July--September 1976. [Phase-change materials]
The document is the second in a series of quarterly progress reports covering activities funded at ORNL by the ERDA Division of Energy Storage Systems to develop low-temperature thermal energy storage (TES) technology. These systems will be based on either sensible or latent heat storage at temperatures up to approximately 250/sup 0/C. At ORNL, research efforts were continued to (a) develop a time-dependent analytical model that will describe a TES system charged with a phase-change material, (b) measure thermophysical properties and melt-freeze cyclic behavior of interesting PCM's and (c) determine crystal lattice structures of hydrated salts and their nucleators. A report on TES subsystems for application to solar energy sources was completed and is being reviewed. In the area of program management, subcontracts were signed with Clemson University, Dow Chemical Company, Suntek Research Associates, and The Franklin Institute. Detailed reviews were completed for ten unsolicited proposals related to TES. Industries, research institutions, universities, and other national laboratory participation in the TES program, for which ORNL has management responsibilities, are listed.
