Abstract

It is the purpose of this work to present an experimental analysis of the thermodynamic cycles in a multi-tubular adsorber of a solar-powered icemaker that uses activated carbon-methanol pair. The experimental cycles were obtained from tests made under different meteorological conditions—mainly the conditions pertaining to cloud cover degree. The system was tested in a Brazilian region close to the Equator (7∘8′S, 34∘50′WG) during the period October-December 2003. On a typical clear sky day, the regenerating temperature reached 94∘C, the condensed methanol mass amounted to 3 kg, and the machine produced 6 kg of ice/m2 day at −3.3∘C, with a net solar coefficient of performance (COPs) of 0.085. These results were compared to those obtained from a similar prototype that utilizes the same adsorptive pair and an usual flat adsorber, tested in Tunisia (35∘45′N, 10∘45′WG).
