Abstract: | The performance of a box-type solar cooker can be represented in terms of two figures of merit, F1 and F2. The second figure F2 is a controlling factor in the sensible heating of a load. The present work validates F2 by computing this figure from experimental data by two different procedures and comparing the results. An attempt has also been made to provide some guidelines for selecting a suitable temperature interval for determination of F2. The results of some experiments to study the effect of number of pots and the load on F2 have also been presented. It is recommended that for standardization tests should be conducted at full load. |
