Example

Redo the preceding example; if FRUL = 5.71 W/m2-°C and collector area is 16 m2, what is the ratio FR /FR ?

Solution

All data are available from the previous example. So, from Eq. (5.57),

AcFrUl

(m cp )c

(m cp)c

£(m cp)min

16 X 5.71 5184

16 X 5.71 5184

G.98

This result indicates that 2% more collector area would be required for the system with a heat exchanger to deliver the same amount of solar energy as a similar system without a heat exchanger.
