Résumé

A resorption system with simultaneous cold and heat production was studied. The heat produced could be used for sanitary or process purposes, or to drive another heat-powered machine. The resorption reactors had MnCl2 and NH4Cl as reactant (which are impregnated in expanded graphite) and NH3 as refrigerant. The combined coefficient of performance and amplification of this system reached 1.3 when the cooling effect was produced at 0°C and heating effect at 7°C with the regeneration temperature of 140°C. Its COP was 0.35 with a specific cooling power of 1.12 MJ/kg.day, and the heat sink in this case remained below the cooling temperature for more than 5 h. Because of the heat production at certain temperature level (from 70 to 80°C) in this study, the released heat could be used to power a silica gel-water adsorption chiller and the overall COP of the combined system would increase dramatically.
