Question From Solar Technologies....

#1)  From system engineering standpoint, describe waysas to how the hot air from a solar collector can be used inbuildings.

#2) Use the data provided in example 3.15 (pp. 118-119) tocompute the available power, outlet temperature, and thermalefficiency at vwind = 2 m/s (all other boundary conditions are thesame as condition No. 4). Compare the results from this newcondition with that from condition No. 4. Note: Please describe theprocedure and equations used for the calculations, and show youwork (or attach your spreadsheet).

____(giwevn question)Example 3.15 Calculation of the availablepower, the outlet temperatures and the thermal efficiency for afacadeintegrated air collector at 800 W/m² irradiance and anambient temperature of 10°C. The ambient temperature equals theinlet temperature Tf,in in the collector. The air duct geometrycorresponds to the examples already calculated with a collectorlength of 2.5 m, and the heat transfer coefficient of the rear Ubis a constant 0.65 W/m²K (side losses ignored).
