Experimental and Theoretical Study of the Energy Flow of a Two Stages Four Generators Adsorption Chiller

This work is concerned with a two stages four beds adsorption chiller utilizing activated carbon-methanol adsorption pair that operates on six separated processes. The four beds that act as thermal compressors are powered by a low grade thermal energy in the form of hot water at a temperature range...
