Resumen de Adsorption cooler design, modeling, and dynamics and performance analyses
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 oC, 18 oC, and 70 oC, respectively. Moreover, results show that the AC can be used for refrigeration purposes at temperatures as low as 2 oC, and that it can also operate during hotter days under temperatures of 42 oC.
