Method for operating an adsorption compressor and adsorption compressor for use in said method

The present invention is directed to a method of operating an adsorption compressor system, which system comprises a hot source and a cold source and at least a first and a second adsorption bed, wherein the first bed has an initial temperature that is lower than the initial temperature of said second bed, in which system heat is circulated using a heat transfer fluid (HTF), the method comprising the following phases: phase A) comprising the steps of: heating the first adsorption bed by feeding HTF to it, coming from said second bed, optionally via said hot source, while maintaining a thermal wave in said first bed; and cooling the second adsorption bed by feeding HTF to it, coming from said first bed, optionally via said cold source, while maintaining a thermal wave in said second bed; wherein phase A) is maintained until the exit temperature of said first bed and said second bed are essentially the same and phase B) comprising the steps of: feeding the HTF effluent of said first bed to said hot source and from said hot source back into said first bed; and feeding the HTF effluent of said second bed to said cold source and from said cold source back into said second bed; wherein phase B) is maintained until the temperature in said first bed is essentially homogeneous and the temperature in said second bed is also essentially homogeneous and lower than the temperature of said first bed, wherein the flow rates of said HTF through said first and second bed may be higher than in phase A).

ADSORPTION HEAT EXCHANGER DEVICES

Adsorption heat exchanger devices (11, 25) are provided for use in solid sorption refrigeration systems (1) together with methods for making such devices and adsorbent structures therefor. The methods include applying a curable binder, in solution in a solvent, to granular adsorbent material, and then evaporating the solvent and curing the binder. The curable binder solution is sufficiently dilute that, during evaporation of the solvent, the binder becomes concentrated around contact points between granules (18) of the adsorbent material whereby localized bonds (19) are formed around the contact points on curing of the binder.
