Abstract

Sorption cooling system based on gas-solid reaction is a newly emerged energy conversion technology which is benign to environment. In this work, sorption cooling system, based on the gas-solid pairs of H₂-La_0.9Ce_0.1Ni₅/LaNi_4.7Al_0.3 and NH₃-NaBr/MnCl₂ is thermodynamically analyzed using the first and second law of thermodynamics. The COP of H₂ - La_0.9Ce_0.1Ni₅/LaNi_4.7Al_0.3 and NH₃-NaBr/MnCl₂ based sorption system is 0.70 and 0.41 respectively while neglecting mass ratio and 0.23 and 0.33 respectively while considering mass ratio as 4. Also it is observed that the sorption cooling system based on NH₃-NaBr/MnCl₂ can produce refrigeration effect below 0°C while H₂-La_0.9Ce_0.1Ni₅/LaNi_4.7Al_0.3 sorption system can be operated at a low temperature of about 130°C. Irreversibility in H₂-La_0.9Ce_0.1Ni₅/LaNi_4.7Al_0.3 sorption system is small in comparison to NH₃-NaBr/MnCl₂ based system, due to lower reaction enthalpy values of regenerating material in case of H₂-La_0.9Ce_0.1Ni₅/LaNi_4.7Al_0.3 system. The reactor mass contributes significantly in the irreversibility of the system.
