SYSTEM FOR UPGRADING WASTE HEAT

摘要

A system comprises first (22A) and second (22B) heat transfer units. In each unit modules (10) comprise first (12) and second (14) connected (16) chamber parts which respectively contain first and second gas adsorbent materials. 1. Higher grade fluid (36) passes over module(s) in first heat transfer unit (R1) to cause gas desorption from the first adsorbent material. 2. Lower grade fluid (44) passes over module(s) in first heat transfer unit (D1) to cause gas adsorption onto the second adsorbent material. 3. Heated lower grade fluid (60) from unit (D1) passed (62) over module(s) in second heat transfer unit (D2) to cause desorption of adsorbed gas from the second adsorbent material, whereby lower grade fluid (46) leaving second heat transfer unit (D2) is cooled. 4. Higher grade fluid from first heat transfer unit (R1) is passed (52) over module(s) in second heat transfer unit (R2) whereby, during adsorption of desorbed gas onto the first adsorbent material, higher grade fluid leaving unit (22B) is heated.
