The invention relates to a method for executing an alternating evaporation and condensation process of a working medium on a heat transfer surface provided simultaneously as an evaporation and condensation surface. The method is characterized in that, during a respective operating cycle from in each case an condensation process and in each case an evaporation process, a condensate film of the working medium which forms during the condensation process is stored permanently in situ on the heat transfer surface and is then evaporated from the heat transfer surface during the evaporation process. In terms of the apparatus, the heat transfer surface () is in the form of an in-situ store for a condensate film () of the working medium which covers the heat transfer surface and does not drip off and remains on the heat transfer surface during the condensation process and evaporates during the evaporation process.

Method and apparatus for executing an alternating evaporation and condensation process of a working medium

The invention relates to an adsorption module, consisting of at least one sorption unit and at least one evaporator/condenser unit, each with inlet and outlet ports for a fluid heat transfer medium, said units being in the same or separate vacuum-tight housings. According to the invention the housing is flat and can be joined to multiple flat housings in a stacked arrangement with a common steam duct.

Adsorption module

The invention relates to a method and a device for operating a cyclical thermal adsorption heating or refrigeration system having a desorption phase and an adsorption phase, comprising at least one adsorber/desorber unit (A/D), a refrigerant cyclically adsorbed during the adsorption phase and desorbed during the desorption phase, and an evaporator/condenser unit (V/K) that acts as an evaporator (V) or as a condenser (K) depending on the process phase. The method and the device intended for carrying out the method are characterized by a cyclic heat recovery that occurs at the same time in a heat recovery circuit having a temporary store (ZS) and a heat transfer medium, comprising the following steps. At the end of the desorption phase, the heat transfer medium having a low temperature is brought from the temporary store into thermal contact with the evaporator/condenser unit, and at the same time the hot heat transfer medium is transferred from the evaporator/condenser unit into the temporary store in a first temporary storage phase. At the end of the adsorption phase, the heat transfer medium having the higher temperature is brought from the temporary store into thermal contact with the evaporator/condenser unit. At the same time, the cold heat transfer medium is transferred from the evaporator/condenser unit into the temporary store in a second temporary storage phase.
