- the storage fluid to be heated comes from the lower - i.e. bottom area of the temperature-stratified storage and the heated storage fluid is removed from it
- the upper area of the memory is layered again.
- the Plant of the high-temperature heat exchanger according to the invention is designed as a finned tube bundle heat exchanger.
- Such finned tube bundle heat exchanger can in advantageously small volume, i.e. compact be dimensioned or designed to be a corresponding to realize high heat transfer capacity.
- the Fins of such a finned tube bundle heat exchanger cause advantageously in flowing, too heating storage fluid only a relatively small Pressure drop so that the thermosiphonic drive does not is disturbed.
- it is important that the Volume flow of the storage fluid to be heated is not too rises sharply, otherwise the heat to be warmed up Storage fluid not to the necessary useful or Storage tank temperature warmed up.
- the thermosiphonic volume flow of the to be heated Storage fluids must be large enough to hold the working fluid the carbon dioxide forming the heat pump is sufficiently deep cool down.
- the riser pipe preferably has one such a clear internal cross-section and such axial length dimension that its thermosiphonic Flow pressure drop a volume flow with lower High temperature heat exchanger outlet temperature of the Heat pump drive means and with high Outlet temperature of the storage fluid to be heated on Has riser pipe outlet of the riser pipe. This will a correspondingly high storage temperature and a high one Achievement figure achieved.

- a typical application or operating case of plant according to the invention is the heating of drinking water, the water in the temperature-stratified storage tank System in the initial state a homogeneous temperature of e.g. 15 ° C.
- the heat pump containing carbon dioxide will be in the store located water with the help of the high temperature heat exchanger warmed up. Because of this warming it experiences this Water has a thermosiphonic buoyancy and flows through the riser pipe provided in the storage in the top Storage area. Here it forms due to the low Density compared to the colder storage water a warm one Layer of water. Without significant mixing of the warm water with the cold water underneath the memory is gradually heated up until finally the warm water layer also covers the lower part of the Memory reached.
- a control device may be provided.
- This control device is, for example, a valve with which it is possible to regulate the volume flow in the riser pipe in such a way that, regardless of the state of charge of the accumulator and / or regardless of the operating state of the heat pump at the riser pipe outlet, an at least approximately constant temperature of the accumulator fluid is established .
