Adsorption cooling apparatus with buffer reservoir

An adsorption cooling apparatus with an intermittently heated adsorbent container containing an adsorbent that exothermically adsorbs a working medium during an adsorotion phase and with addition of heat again desorbs during a subsequent desorption phase at higher temperatures and with a condenser that leads condensed working medium through a connection line to an evaporator which is in turn connected with the adsorbent through a working medium vapor line and which takes up heat from the medium to be cooled during the adsorption phase, wherein the condenser is coupled to a buffer reservoir that buffers at least a part of the condensation heat of the working medium vapor and that can again dissipate the stored heat into the surroundings even during the adsorption phase, and wherein the evaporator contains wetting agents which effect a homogeneous distribution of the liquid working medium inside the evaporator.

An adsorption cooling apparatus with an intermittently heated adsorbent container containing an adsorbent that exothermically adsorbs a working medium during an adsorption phase and with addition of heat again desorbs during a subsequent desorption phase and higher temperatures and with a condenser that leads condensed working medium through a connection line to an evaporator which is in turn connected with the adsorbent through a working medium vapor line and which takes un heat from the medium to be cooled during the adsorption phase, wherein the condenser is coupled to a buffer reservoir that buffers at least a part of the condensation heal of the working medium vapor and that can again dissipate the stored heat into the surroundings even during the adsorption phase, and wherein the working medium vapor line contains a regulation element which narrows the flow cross section when the evaporator temperatures are too low.

A method for the operation of an adsorption cooling apparatus with an intermittently heated adsorbent container containing an adsorbent that exothermically adsorbs a working medium during an adsorption phase, and that, with addition of heat, again desorbs during a subsequent desorption phase at higher temperatures, and with a connected condenser disposed within a buffer reservoir and that leads condensed working medium into an evaporator which is in turn connected with the adsorbent through a working medium vapor line, wherein the desorption phase has less than one-third the duration of the adsorption phase, and that the condensation heat is buffered during the desorption phase by a heat reservoir medium contained within the buffer reservoir and that most of the buffered heat is again dissipated during the adsorption phase.
