With the encapsulation of a pipe which can be subjected to pressure, e.g. a refrigerant-channelling pipe and/or its casting into a pressure-resistant material which solidifies well, protection against outflowing gas and/or liquid, for example refrigerant, is achieved. A particular advantage of this pipeline system is that, owing to the core pipe as condenser, the refrigerant can be used, without danger and without a high-loss heat-exchange process, directly for heating purposes. The incorporation of a shut-off valve into the return pipes of each heating circuit brings about material-saving and cost-saving effects. As a result, the return pipes can be kept smaller in diameter than the supply pipes of the heating circuit. A material-saving advantage is obtained in that the release valve incorporated into the return of each heating circuit (heat-discharge circuit) can be connected directly to a heat-receiving circuit fitted on the outer wall. A further advantage is achieved if the interspaces between core pipe and protective casing are connected to a water-channelling pipe system, because then the pipeline system can be used from time to time, i.e. as required, as an instantaneous heater and/or for preparing hot water. |
