Embodiment Construction

[0067] A first embodiment of a regenerator 100 according to the invention is shown diagrammatically at Figure 1 to Figure 7 middle. The heat accumulator 100 comprises the main components as follows: a housing 10 in which a heat storage medium 15 is received, a heat exchanger 20 and an electric heating device 50 .

[0068] The electric heating device 50 is designed to receive electrical energy and convert the electrical energy into heat energy. To this end, it can have, for example, resistors through which the current is transmitted during operation.

[0069] The generated thermal energy is discharged to the thermal storage medium 15 ( figure 2 and image 3 ). The heat storage medium 15 is metal, preferably aluminum.

[0070] Thermal energy can be transferred from the heat storage medium 15 via the heat exchanger 20 to a heat carrier fluid that flows or is pumped through the heat exchanger 20 .

[0071] Electric energy in the form of thermal energy can be stored by mean...

Abstract

The invention relates to a heat reservoir comprising: a housing for accommodating a heat storage medium; a heat storage medium accommodated in the housing; and a heat exchanger in which a heat transfer fluid can be conveyed and which is arranged such that heat from the heat storage medium can be transmitted to the heat transfer fluid. According to the invention, the heat reservoir is characterised in that an electrical heating device is provided, which is designed to convert electrical energy into thermal energy. The electrical heating device is arranged such that, in operation, it heats the heat storage medium, wherein the heat storage medium that is heated by the electrical heating device is a metal. A corresponding method is also disclosed.

Description

technical field [0001] A first aspect of the invention relates to a heat accumulator according to the subject-matter of claim 1 . [0002] Another aspect of the invention also relates to a method of operating a heat accumulator according to the subject-matter of claim 17 . Background technique [0003] Regenerators, also known as heat storage devices, include heat storage media that store thermal energy by being heated. Common heat storage media have relatively high specific heat capacities. They can therefore store considerable amounts of energy without excessive temperature changes. The thermal energy emitted from the heat accumulator is used in many different applications. [0004] A common regenerator includes a housing for receiving a thermal storage medium and the thermal storage medium received in the housing. Furthermore, the heat accumulator comprises a heat exchanger for carrying the heat carrier fluid, which is configured to transfer heat from the heat storage...
