| 1. A method of making a heat exchanger, the method comprising:
surrounding a fin set that includes a plurality of fins arranged parallel to each-other with an interval therebetween with
a metallic framework such that the metallic framework is arranged to surround end faces of the fin set in an arrangement direction
of the fins and end faces of the fins in the lengthwise direction of the fins;
penetrating the fin set with a serpentine heat transfer tube such that said tube penetrates the fin set in an arrangement
direction of the fins and has u-shaped parts protruding out of the metallic framework;
coating the surfaces of the framework, fin set, and heat transfer tube with adsorbents that adsorb moisture from the air and
desorb moisture into the air; and
controlling air flow inside the heat exchanger such that air velocity is between 0.5 and 1.5 meters per second, inclusive.
