Readsorption occurs inside a sorbent-bed heat exchanger during the pressurization and depressurization processes, causing the adsorbate to be relocated from one end of the sorption bed heat exchanger to the other. In this paper, the readsorption processes are quantitatively determined for both the pressurization and depressurization processes in a sorbent-bed heat exchanger with a uniform initial temperature, loading, and pressure. Also, the readsorption that occurs during a typical operation of a two-bed sorption heat pump is quantified. The results show that the readsorption can cause as much as 30 percent of the ammonia in a sorbent-bed heat exchanger to be reallocated.
