Résumé

This paper presents an adsorption cooler (AC) driven by the surplus heat of a solar thermal domestic hot water system to provide cooling to residential buildings. A cylindrical tube adsorber using granular silica gel as adsorbent and water as adsorbate is considered. The AC is modelled using a two-dimensional distributed parameter model that was implemented in previous adsorption heating and cooling studies. The performance coefficients of the resultant thermally driven colling system are obtained for a broad range of working conditions. The thermally driven AC has a coefficient of performance (COP) of 0.5 and a specific cooling power (SCP) of 44 W.kg-1, considering condenser, evaporator, and regeneration temperatures of 15 °C, 18 °C, and 70 °C, respectively. Moreover, results show that the AC can be used for refrigeration purposes at temperatures as low as 2 °C, and that it can also operate during hotter days under temperatures of 42 °C
