Abstract

The waste heat utilisation increases the inlet temp. of fresh water at a hot water boiler. The system has a modular housing formed from conventional drain pipes, and uses a heat exchange consisting of a copper pipe in a spiral coil.The water flow is such that drain water and pressurised water and guided in a counterflow. During operation the system is filled with water, and is automatically emptied after termination of operation. The downwards flowing waste water is guided through a riser such that the heat exchanger is completely covered.

Description

Die Erfindung betrifft eine Einrichtung zur Abwärmenutzung von Dusch­ wasser, bei der das warme Duschab­ wasser (Eintritt bei 3) zur Erwärmung des kühleren Frischwassers (Eintritt bei 1, Austritt bei 2) genutzt wird und somit zu einer erheblichen Energieein­ sparung beiträgt. Das abfließende Duschwasser besitzt in den meisten Fällen noch eine Temperatur von ca. 38°C. Dieses warme Wasser wird am Anschluß (3) in die Vorrichtung so eingeleitet, daß es einen Großteil seiner noch vorhandenen Wärmeener­ gie an das kalte Frischwasser abgibt und somit das Frischwasser vor der Erwärmung durch einen Warmwasser­ bereiter auf ein höheres Temperaturni­ veau anhebt. Dadurch kann der Energiebedarf des Warmwasserberei­ ters heruntergeregelt werden.The invention relates to a device for waste heat use of shower water, in which the warm Duschab water (entry at 3 ) for heating the cooler fresh water (entry at 1 , exit at 2 ) is used and thus contributes to a considerable saving of energy. The outflowing shower water still has a temperature of approx. 38 ° C in most cases. This warm water is introduced into the device at the connection ( 3 ) in such a way that it emits a large part of its remaining heat energy to the cold fresh water and thus the fresh water rises to a higher temperature level before being heated by a hot water heater. This allows the energy requirements of the water heater to be reduced.
