Performance analysis of a triple-effect absorption cooling cycle using aqueous (lithium, potassium, sodium) nitrate solution as a working pair

Results show that the Alkitrate triple-effect cycle has a slightly higher efficiency as compared to the H2O/LiBr triple-effect cycle at generator temperatures of over 180 °C. Moreover, the practical operation of a H2O/LiBr triple-effect cycle at temperatures higher than 180 °C suffers from the above mentioned problems related to the thermal stability and corrosion of the working pair.
