Abstract

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 wit…
