Abstract
A device for detecting and signalising a leakage in a double-walled conduit system of a heat exchanger for heating fresh water by way of heat from waste water in the sanitary field as well as a heat exchanger including such a device. The device has an elastic element and a signalisation unit, wherein the elastic element is essentially liquid-tight and the signalisation unit is configured to generate an acoustic signal and the signalisation unit is activatable by way of a mechanical deformation of the elastic element.
Claims16
A device
- for detecting and signalising a leakage
- in a double-walled conduit system of a heat exchanger for heating fresh water by way of heat from waste water in the sanitary field,
- comprising
- an elastic element,
- and a signalisation unit,
- wherein
- the elastic element is essentially liquid-tight, and wherein
- the signalisation unit is configured to generate an acoustic signal, and
- the signalisation unit is activatable by way of a mechanical deformation of the elastic element.
10 The heat exchanger according to claim 8, wherein an electrical current circuit is closed if the overpressure in the cavity exceeds 20 mbar.
