SOLAR SORPTION REFRIGERATOR

The performance of a solar sorption refrigerator is studied experiment ally for three configurations of its collector cover : with Single gla zing, with double glazing and with single glazing plus transparent ins ulation. The collector consists of fifteen stainless steel tubes havin g a selective surface (with good thermal absorption coefficient) and c ontains granular activated carbon adsorbent with ammonia refrigerant. The collector surface area is approximately 1.43 m(2) and contains abo ut 17 kg of carbon. The collector operates with good efficiency (36 to 47% depending on conditions) when in the single glazing configuration . (C) 1997 Elsevier Science Ltd.
