Abstract
Layered adsorbent-substrate tubes are prepared by a method comprising heating the surface of an aluminum substrate, contacting the surface of the substrate with a slurry containing the adsorbent and a binder, and heating the coatings to form hardened surfaces which can have excellent adsorption and mechanical properties in devices for cooling or heating by adsorption of refrigerating fluid on a solid adsorbent.
Claims5
A zeolite coated heat exchanger tube comprising:
- (a) a continuous length of tube comprising a high heat conductivity material, said tube having an inside surface, a first end, and a second end opposite;
- (b) an aluminum substrate surface disposed on the inside surface of said tube;
- (c) a zeolite layer disposed on said aluminum substrate surface;
- (d) a vapor tight seal disposed at said first end and said second end creating a vapor space inside said tube surrounded by said zeolite layer;
- and
- (e) a refrigerant disposed within said vapor space at a level up to one-half of the saturation value of the zeolite layer.
