DOUBLE LAYER SOLAR HEATING-AND-COOLING THERMOSYPHON SYSTEM

摘要

A solar liquid-heating-and-cooling system (20) includes: 1. a hot-liquid storage-tank (22); 2. a hot-liquid manifold-tank (26); 3. a coaxial heating-and-cooling-tube (24) that connects downward from the hot-liquid storage-tank (22) to the hot-liquid manifold-tank (26); 4. a double layer heating-and-cooling collector-array-panel (32) located beneath the hot-liquid manifold-tank (26), the panel (32) including, connected to the hot-liquid manifold-tank (26) a. an upper layer of glazed heating-tubes (36); and b. a lower layer of unglazed cooling-tubes (56); 5. parabolic-trough mirror reflectors (64) that are located between the upper and lower layers of tubes (36, 56); 6. cold-liquid manifold-tank (92) located below the panel (32) connected to lower ends both of the glazed heating-tubes (36) and of the unglazed cooling-tubes (56); 7. a cold liquid storage tank (98); and 8. a coaxial heating-and-cooling-tube (96) that connects downward from the cold-liquid manifold-tank (92) to the cold liquid storage tank (98).
