PREDICTION OF THE PERFORMANCE OF SOLAR HEATING SYSTEMS UTILIZING ANNUAL STORAGE

Integrated performance equations which incorporate effects of finite storage are derived for solar heating systems such as those using annual storage in which the well-mixed storage temperature rises or falls monotonically. These equations accurately predict in a single step the performance of ordinary systems over an entire day, and annual storage systems over an entire month. Over a year, monthly application of the integrated equations predicted annual performance within about two per cent relative to an hourly simulation. © 1979.
