Potential benefits of distributed PCM thermal
This report examines the benefits of passive thermal storage by means of phase change material (PCM) distributed throughout the wall and ceiling surfaces of a building, as would occur if the wallboard were impregnated with PCM. Surface heat transfer is expected to be adequate for thermal storage capacity up to 40-Btu/ft/sup 2/ of surface area. Sums of daily energy balances during the heating season indicate that use of PCM-impregnated wallboard with a 40-Btu/ft/sup 2/ capacity would provide adequate storage for direct gain systems with the largest practical window area in Denver, Boston, and Fort Worth. It is shown that distributed PCM thermal storage offers the opportunity to obtain several ton-hours of ventilative cooling per night throughout much of the US during July. 17 refs., 9 figs.
