Abstract

Für einen Wärmetauscher (2) für flüssige Wärmetauschmittel für ein wechselweises, ventilgesteuertes Erwärmen oder Kühlen einer der Flüssigkeiten wird zur Erzielung einer hohen Regelgüte einer Ventileinrichtung (3) und geringer Temperaturdifferenzen zwischen Zu- und Ablauf des zum Erwärmen und Kühlen dienenden Wärmetauschmittels vorgeschlagen, daß im Ablauf des Wärmetauschers (2) für die erste, dem Erwärmen und Kühlen dienende Flüssigkeit bzw. Wärmetauschmittel ein Temperatursensor (18,19) angeordnet ist zur Steuerung/Regelung gesonderter, in einem Heißzulauf (7) und in einem Kaltzulauf (14) der ersten Flüssigkeit bzw. des ersten Wärmetauschmittels in der Ventileinrichtung angeordneter Ventile (16,17).

Figure 00000001
For a heat exchanger (2) for liquid heat exchange medium for an alternate, valve-controlled heating or cooling of one of the liquids is proposed to achieve a high control quality of a valve device (3) and small temperature differences between the inlet and outlet of the heat exchanger used for heating and cooling, that in Drainage of the heat exchanger (2) for the first liquid used for heating and cooling or heat exchange medium, a temperature sensor (18, 19) is arranged for control / regulation separately, in a hot inlet (7) and in a cold inlet (14) of the first liquid or the first heat exchange medium of valves (16, 17) arranged in the valve device.
