ABSTRACT:
A closed-loop, incompressible-liquid circulating, hydronic heating system, for instance, a hot water heating system, which utilizes a Venturi-type control device to effect communication between the circulating hydronic heating system and a storage tank. The storage tank, which is maintained at ambient atmospheric pressure, is connected to the throat of the Venturi. The inlet and outlet of the Venturi are connected to the pump outlet and inlet, respectively, in parallel with the main circulating loop. The Venturi control device automatically controls the pressure in the circulating system by means of controlling the flow of incompressible-liquid between the storage tank and the incompressible-liquid circulating system. The Venturi control device responds automatically to changes of pressure in the circulating system. The pressure differential between the Venturi throat and the Venturi inlet remains constant. Thus, if the Venturi throat pressure is set so as to be at or near atmospheric during normal operating conditions of the circulating system, when the pressure of the circulating system drops, the Venturi throat pressure will drop below atmospheric and draw incompressible liquid (e.g., water) from the storage tank into the circulating system. Conversely, if the pressure in the circulating system should rise, the Venturi throat pressure would rise above its ambient atmospheric level to thereby vent some of the water from the circulating system back into the storage tank.
