PROBLEM TO BE SOLVED: To obtain an adsorbent for a heat pump which does heat exchange efficiently by the use of synthetic zeolite. SOLUTION: The adsorbent comprises metal-substituted synthetic zeolite in which at least 33.3% of the total replaceable charge of the synthetic zeorlite is replaced with other metal ions. The substituent divalent metal ions are one or more kinds of metal ions, for example, selected from Mg2+, Ca2+, Ba2+, Sr2+, Mn2+, Co2+, Ni2+, Cu2+, Cd2+, Zn2+, Ge2+, Sn2+, and Pb2+, or univalent metal ions of K+ or Ag+. |
