Abstract

Many industrial sectors reject heat to the atmosphere in the form of hot water with temperatures between 40° and 70°C. This rejected heat, owing to its low temperature, is of little significant to the generating processes unless a means to boost its temperature is available. However, there is a device with which this low grade heat can be upgraded; that is. by employing a vapor absorption heat transformer (AHT). It is anticipated that by using this device the amount of heat rejected to the atmosphere can be reduced by recycling the upgraded low heat back to the process. This research will investigate the performance of Ammonia-Water and Lithium Bromide aqueous solutions in a single stage AHT. Comparison will be made between the findings of the two proposed aqueous solutions for the same system and operating parameters to determine the relative merit of each one.
