Abstract: Disclosed is a vacuum container for an adsorption refrigeration machine, the vacuum container being connected to a condenser unit of the adsorption refrigeration machine via a connection that permits the passage of vapor. The container has a discharge arrangement and at least one cooling element. The connection means are provided with at least one component for shutting off or regulating the flow of fluids.

Abstract: The invention describes a negative-pressure tank having a partition, the partition including at least two walls, and the negative-pressure tank including at least two chambers, and a free space being present in the partition in which an ambient pressure prevails. The invention further describes a sorption machine having a negative-pressure tank.

Abstract: The invention relates to a distributor device that can be connected to a sorption machine and can be used with the sorption machine for the hydraulic and/or electric connection of different components. Said device comprises at least one pump (1) and components for driving, measuring, heat-exchanging, controlling and/or regulating a driving, recooling, heating and/or cooling circuit of the sorption machine.

Abstract: The invention relates to an evaporator for sorption machines, comprising a heat exchanger provided with at least one tube and/or preferably tubular accessories, and a porous material which allows vapour to pass through is in contact with the tubes and/or the tubular accessories. The invention also relates to the use of fibrous material as filing material in an evaporator.

Abstract: The invention regards a self-supporting, substantially cuboid vacuum container which is particularly thin-walled, and the use thereof especially for adsorption devices.

Abstract: The invention relates to the use of a pressure-reducing element or splitting volume flows in a sorption machine, wherein a single volume flow from a recooling device is split into at least two volume flows. A first volume flow flows through at least one tube of a first tube section into a condenser and a second volume flow through at least one tube of a second tube section into an absorber, at least one of the two tube sections leading away from the recooling device or at least one of the two tube sections leading back to the recooling device comprising at least one pressure-reducing element.

Abstract: The invention relates to the use of an adsorbent instead of a condenser in a heat pump/refrigerating machine as well as the use of said adsorbant during the reduction of the vapor pressure in a heat pump/refrigerating machine in order to improve the desorption capacity. The invention further relates to a refrigeration method in which preferably two different adsorbants are used in two stages.
