Abstract: Disclosed is a refrigeration unit having an accumulator, a refrigeration system and a method for controlling a refrigeration unit having an accumulator, wherein the refrigeration unit has a refrigeration chamber for receiving and storing goods to be refrigerated, an accumulator having an accumulator holder in which a storage medium is accommodated, a heat exchanger, a controller and a coolant line arrangement which can be connected to a coolant supply network via connections. The coolant line arrangement is guided through the accumulator holder, and the heat exchanger is thermally coupled to the storage medium accommodated in the accumulator holder. A coolant control device is arranged in the flow pipe of the coolant arrangement, wherein the storage medium accommodated in the accumulator holder is cooled via a coolant in the coolant line arrangement, and the heat exchanger is cooled via the storage medium.

Abstract: An energy store includes a housing having a storage medium with latent heat during a phase transfer, which is provided during operation for solidifying into a solid phase and for melting into a liquid phase, including a first storage region which is provided at least periodically for the solid phase and in which an extractor heat exchanger is arranged for extracting heat, wherein the first storage region has a vertical axis, including a second storage region provided for the liquid phase, when the solid phase is present in the first storage region, wherein at least sections of the second storage region are provided as a casing around the first storage region, wherein at least one portion of a regeneration device is arranged in the second storage region for supplying heat.
