Abstract

Many industrial sectors reject heat to the atmosphere in the form of hot water with temperature between 40 degree C and 70 degree C. This low grade heat can be upgraded by using a vapor absorption heat transformer (AHT). The present study investigates the performance of Ammonia-Water and Lithium- Bromide aqueous solutions by employing the second-law energy principles in a single stage AHT and compares them for the same system and operating paprameters. The investigation of a solution's performance characteristics is conducted by solving the governing equations with a computer. Comparison is made between the findings for the two proposed aqueous solutions to determine the relative merit of each one.
