14. Solar thermal cold storage for 24x7operations using thermal storage
Cold Room PCM Storage
Gassifier based hot water generation
24*7 Operations
by Solar Thermal
Backup of gasifier incase
Of solar deficiency
Gasifier as back up to Solar Hot water Generator. Backup
becomes active when the hot water from solar is not at 120
deg. C, or when the cold storage is required when Sun is not available.
