Abstract: An adsorption cooler operating in accordance with the periodical adsorption principle and consisting of at least one adsorption container filled with zeolite. At least one condenser with a collecting container for the water which desorbs from the zeolite and an insulated cooling container which may be closed by a shut-off member are serially connected with the adsorption container. In the cooling container, the adsorption cooler generates ice in stages which acts as a cold buffer. The system is usable for example in solar cooling systems, vehicle air conditioning units and air conditioning insulation as well as beverage coolers.

Abstract: Periodic absorption apparatus with the substance pair zeolite/water being used as electro-head storage devices. Due to the heat pumping effect there can be a 30% savings of power.

Abstract: The invention describes portable cooling and heating devices and their process of operation in accordance with the adsorption principle utilizing the adsorption substance pair of zeolite-water. The devices operate without substance and heat exchange from the environment, in that the evaporation heat originates from the solidifying heat of a non-evaporating amount of water and that the released adsorption heat is stored in the form of tangible heat of the zeolite filler. The ice which had been generated during the adsorption process is suitable for human consumption.

Abstract: Blanks are provided from zeolite (1) which adsorb and desorb adsorbed substances and are provided with metal textures (3). The stability and the low heat conductivity of the blanks are increased by the metal textures (3). The metal texture is permanently connected with heat exchanger surfaces in a manner to provide good heat conductivity by means of known connecting techniques. The blanks contain separate flow conduits (4) for the adsorbed substances. The binder components in the zeolite filling are lesser in the inside of the blanks than in the outer areas.

Abstract: A plurality of adsorption containers are provided which are separated into heater adsorber zones and condenser evaporator zones. The zones are successfully rotated through flow segments which form a passageway for heat carrier flows. The heater adsorption zones contain an adsorption substance from which an operating substance is extracted by adsorbing heat from a heat carrier flow and is again adsorbed by emitting heat to a further heat carrier flow. The operating substance condenses and evaporates by means of a heat exchange with further heat exchangers. The adsorption devices are suitable as cooling devices and heat pumps as well as heat transformers and heat exchangers.

Abstract: A sorption unit will be equipped with a heat discharge controller (41) that can be monitored/controlled by the consumer (50) in order to make a simultaneous use of the sorption unit as heat pump and heat reservoir possible.

Abstract: Process for storing heat and for upgrading its temperature, in which a working substance is expelled from an absorbing substance by means of heat of a predetermined intermediate temperature range, the vapor of the working substanced generated during the expulsion step being condensed at a comparatively low temperature and the condensed working substance being evaporated in the intermediate temperature range and being absorbed in the absorbing substance under an increased pressure and at a relatively high temperature while generating heat of absorption, in which a zeolite is used as the absorbing substances and water is used as the working substance.

Abstract: In a system with at least one absorption heat pump, a working medium is generated in a generator or explusion unit by the input of heat energy of relatively high temperature, from an absorption material. The generated working medium is condensed in a condenser and then undergoes expansion in an expansion unit. The expanded, condensed working medium is evaporated in an evaporator with the input of heat energy at a relatively low temperature and the evaporated working medium is absorbed again, in an absorber, in the absorption material. The heat energy, used for generation of the working medium from the absorption material, is so stored for the heat pump that the heat energy, as taken from the store, is on hand at a temperature which is high enough for the generation of working medium from the absorption material.The heat store may preferably take the form of a sorption store, comprising a zeolite as sorption material and forming a part of a further discontinuously operated absorption heat pump.
