CIRCULATING PUMP UNIT AND SOLAR THERMAL PLANT
First Claim
1. A circulation pump assembly comprising:
- a circulation pump, a liquid storage being connected to the circulation pump assembly via a heating circuit;
an electric drive motor;
a control device integrated into the circulation pump assembly; and
at least one internal temperature sensor arranged in the circulation pump assembly to detect a temperature of a medium delivered by the circulation pump assembly and issue a corresponding temperature signal to the control device, wherein the control device is configured, on the basis of the temperature signal of the internal temperature sensor, to approximately determine the temperature of liquid in the liquid storage.

Abstract
A circulation pump assembly (2) includes an electric drive motor (6) and a control device (10) integrated into the circulation pump assembly (2). At least one internal temperature sensor (16) is arranged in the circulation pump assembly (2) and detects the temperature of the medium delivered by the circulation pump assembly (6) and issues a corresponding temperature signal (42) to the control device (10). The control device (10) is configured, on the basis of the temperature signal (42) of the internal temperature sensor (16), to approximately determine the temperature of the liquid in a liquid storage means (26) which is connected to the circulation pump assembly (2) via a heating circuit (28).
