Evaluation of thermal-storage concepts for solar-cooling applications
Technical Report
·
OSTI ID:5988740
Various configuration concepts for utilizing thermal energy storage to improve the thermal and economic performance of solar cooling systems for buildings were analyzed. The storage concepts evaluated provide short-term thermal storage via the bulk containment of water or salt hydrates. The evaluations were made for both residential-size cooling systems (3-ton) and small commercial-size cooling systems (25-ton). The residential analysis considers energy requirements for space heating, space cooling and water heating, while the commercial building analysis is based only on energy requirements for space cooling. The commercial building analysis considered a total of 10 different thermal storage/solar systems, 5 each for absorption and Rankine chiller concepts. The residential analysis considered 4 thermal storage/solar systems, all utilizing an absorption chiller. All 14 systems were simulated in Miami, Phoenix, Forth Worth and Washington, D.C. The trade-offs considered include: cold-side versus hot-side storage, single vs multiple stage storage, and phase-change vs sensible heat storage. This report describes the methodology, models and system configurations utilized, and presents thermal and economic results.
