The invention relates to a
system (1) for cooling and / or heating a supplied process medium flow (P), preferably air, from an at least substantially closed room and / or at least substantially closed circulation
system, in particular an
air conditioning system (1) for controlling the
air temperature of buildings, in particular residential, office, administrative and / or industrial buildings, preferably according to DIN 1946 (as at October 2024), further preferably for controlling the temperature of air during the production and / or
processing of food, having at least one first
thermal energy storage device (2) having at least one
energy storage material (3) for cooling by storing
thermal energy and / or heating by releasing
thermal energy, at least one second
thermal energy storage device (4) having at least one
energy storage material (3) for cooling by storing thermal energy and / or heating by releasing thermal energy, wherein the
energy storage devices (2, 4) are arranged in such a way that, alternately and / or selectively, the process medium flow (P) is supplied to the first energy storage device (2) and, in particular simultaneously, the second energy storage device (4), in particular for reactivating the energy
storage material (3), is supplied with an external medium flow (A), in particular having external air, from outside the room and / or the circulation system, or the second energy storage device (4) is supplied with the process medium flow (P) and, in particular simultaneously, an external medium flow (A), in particular having external air, is supplied to the first energy storage device (2), in particular for reactivating the energy
storage material (3), from outside the room and / or the circulation system.
