AHR Adsorptive Heat Recovery
AHR Adsorptive Heat Recovery : A vapor-phase process for removing water from other vapors by selective adsorption in a bed of zeolite molecular sieve, and regenerating the adsorbent by passing a noncondensible gas through it at essentially the same temperature and pressure. The heat of adsorption is stored as a temperature rise within the bed, and provides the heat required for desorption
