WebbIn some European standards, however (e.g. EN 12975-2: 2006), the average temperature is used, Tm, defined as the arithmetic average of the inlet and outlet temperatures [ ( Ti + To )/2] and the efficiency is plotted against ( Tm − Ta )/ Gt. In this case the collector instantaneous efficiency is given by: (4.35) WebbSome results of this calculation are shown in Figure 5. As the curves in Figure 5 suggest, the exit diameter of about 290 mm provides a suitable ratio between the intercept and …
