Circulation system for solar collectors and heating systems

The circulation system includes a pump (26) for generating a fluid volume flow from a heater (10) to a heat pick-up (14). The pump operates in dependence on the fluid temperature difference between the heater and the pick-up. The pump has a dc motor (24). The rotation rate of the motor can be regula...

Beschreibung
Zusammenfassung:	The circulation system includes a pump (26) for generating a fluid volume flow from a heater (10) to a heat pick-up (14). The pump operates in dependence on the fluid temperature difference between the heater and the pick-up. The pump has a dc motor (24). The rotation rate of the motor can be regulated continuously in dependence on the fluid temperature difference to adapt the flow volume to the heating power of the heater. Preferably, the motor is a brush free, electronic commutator dc motor. The pump and the motor may be magnetically coupled. The system may have a regulator (22) for adjusting the motor rotation rate in dependence on the fluid temperature difference from a characteristic curve. The regulator may also switch the motor on or off on reaching a first or a second temperature difference threshold.
