CALCULATION OF HEAT DISSIPATION DUE TO PO OR THERMAL CONDUCTION IN THE GENERATOR OF A CHEMICALLY-ACTIVATED THERMAL MACHINE

A calculation of the heat dissipation resulting directly from poor the rmal conduction inside a solar collector filled with a microporous sol id adsorbant has been carried out using an exergetic local balance. Th e computed result is 180 kJ m-2 for the collector studied. The same ca lculation has given the decrease in exergetic dissipation when the qua lity of thermal transfer is improved. Thus, one is able to estimate th e importance of these improvements by comparing them to the improvemen ts that can also be achieved with the other parts of the machine.
