Balanced adsorbent refrigerator
First Claim
1. A heat transfer apparatus which uses a heat source to generate a cooling effect, the apparatus comprising:
- a first vessel having a first aperture and containing an adsorbent material having an adsorbing capacity;
a second vessel having a second aperture, the second aperture connected to the first aperture of the first vessel with a conduit, the conduit providing a fluid passage between the vessels, the vessels and the conduit forming a sealed volume capable of maintaining less than atmospheric pressure therein; and
a quantity of working substance within the scaled volume, the quantity including a portion of working substance in the second vessel, the working substance being capable of being strongly adsorbed by the absorbent material, the adsorbing capacity of the adsorbent material being sufficient to adsorb by sublimation at least part of the portion of working substance in the second vessel when substantially the entire portion of working substance in the second vessel is in a solid state.

Abstract
A heat transfer apparatus that uses an adsorbent material to generate a cooling effect. The heat transfer apparatus includes a first vessel containing adsorbent material and a second vessel interconnected to the first. A working substance is contained within the two interconnected vessels. The adsorbent material and working substance are sized such that the working substance is completely adsorbed in both liquid and solid states by the adsorbent material from the second vessel into the first, cooling the second vessel and heating the first. Complete adsorption includes adsorption of the working substance by vaporization when the working substance is in a liquid phase and adsorption by sublimation when the working substance is in a solid phase. The second vessel contains a compressible foam which accommodates the expansion of the working substance when it changes phase from a liquid to a solid and prevents the second vessel from breaking.

38. A method for transferring heat and a working substance between a first vessel containing an adsorbent material and a second vessel connected to the first vessel, the two vessels defining a sealed volume containing a working substance in a liquid phase, the method comprising:
-
allowing a portion of the working substance to vaporize by adsorption and transfer from the second vessel to the adsorptive material in the first vessel, thereby causing a remaining portion of the working substance to freeze, creating a frozen working substance; and continuing to adsorb the frozen working substance by sublimation from the second vessel to the adsorptive material in the first vessel. - View Dependent Claims (39, 40)
