| Outline of Final Research Achievements |
Trial tests of lettuce hydroponics (HP), aquaculture of catfish (AC), and aquaponics (AP) were performed. Accumulation of nitrate nitrogen and phosphate in the nutrient solution was reduced in the AP and HP groups. Nitrifying bacteria and nitrate bacteria were detected in the nutrient solution. AP has been shown to be a sustainable cultivation system even in small systems. A demonstration test of a desiccant cooling system using hot air of about 43C from the low temperature waste heat of about 98C of an incinerator was conducted in a strawberry greenhouse. Cooling ability was 175 W, and COP was estimated to be 0.32. It was confirmed that the moisture adsorbed on the adsorbent can be desorbed in this system, and thus the possibility of cooling using waste heat was shown.
