Patent ID: 7997098

Claim:
An adsorption heat exchanger including a heat exchange tube through which heat medium circulates and fins which are attached to the heat exchange tube and on the surfaces of which an adsorbent is carried, said adsorption heat exchanger for bringing air passing therethrough into contact with the adsorbent carried on the fins, wherein a part of said adsorption heat exchanger located upstream in air flow constitutes an upstream part and a part of said adsorption heat exchanger located downstream in the air flow constitutes a downstream part, an adsorption layer made of a mixture having a ratio of adsorbent and binder is formed on the surfaces of the fins, a thickness of the adsorption layer in the downstream part is substantially the same as that of the adsorption layer in the upstream part, and the downstream part has a mixture ratio having a higher mass content of adsorbent to binder in the adsorption layer than the mixture ratio of the upstream part.
