| Outline of Final Research Achievements |
This study developed a zero-energy cool chamber (ZECC) with a solar-driven adsorption refrigerator that does not use electricity. It consists of a solar collector containing activated carbon as an adsorbent, a condenser and an evaporator. It cools water based by evaporating methanol and adsorbing it on activated carbon, and then makes ice. The methanol adsorbed on the activated carbon is desorbed by applying solar heat. The ice is then used to cool the storage space. During evaporation of methanol inside the evaporator at adsorption phase, the evaporator temperature reduced to -10°C that triggered the transforming process of liquid water to solid ice. We obtained about 3.5kg ice per day. The water evaporative cooling system also cools the storage space by evaporating water from the wet walls containing wet filler. The combined use of two cooling systems reduced the average inside temperature and extended the shelf life of tomatoes from 7 to 23 days.
