| Abstract: | Three strategies for solar collector operation are defined. These involve keeping one of the following constant during the day: - 1. (i) the average working fluid temperature,
- 2. (ii) the outlet temperature and
- 3. (iii) the inlet temperature.
A graphical and analytical method previously developed by the authors was generalized to analyse and compare these strategies. For a constant flow rate, the best strategy is to maintain a constant inlet temperature. A constant outlet temperature is recommended when flow-rate control is possible. |
