Embodiment Construction

[0044] figure 1 A heating installation is shown with a hydraulic unit 2 according to the invention, a heat source in the form of a primary heat exchanger 4 and two heating circuits 6 and 8 . The heating circuit 6 is here a heating circuit extending through heating bodies 10 (only one is shown schematically in the figure), while the heating circuit 8 is a heating circuit forming a floor heating system. It is understood here that the heating circuit 8 can in turn be subdivided into a plurality of floor heating circuits. The primary heat exchanger 4 is in particular part of a gas-fired heating boiler. Thus, the primary heat exchanger 4 and the hydraulic unit 2 can be integrated as a whole into a compact heating system, in particular a gas boiler. In this case, the hydraulic unit 2 integrates all important hydraulic components required for operating the heating system.

[0045] The hydraulic structural unit 2 has a heat source outlet 12 and a heat source inlet 14 , to which the...

Abstract

The invention relates to a hydraulic unit for a heating or air-conditioning system, comprising at least one return connection (20) for a heating circuit (6), a first feed connection (16) for a heating circuit (6), a heat source outlet (12) which is fluidically connected to the return connection (20), a heat source inlet (14) which is fluidically connected to the first feed connection (16), and a circulating pump set (28) disposed in a flow path between the return connection (20) and the heat source outlet (12) or in a flow path between the heat source inlet (14) and the first feed connection (16), said circulating pump set having at least one second return connection (18) which is fluidically connected to the heat source inlet (14) and the return connection (20), at least one mixing valve (54) being arranged in a flow path from the heat source inlet (14) to the second feed connection (18) and / or in a flow path from the return connection (20) to the second feed connection (18).

Description

technical field [0001] The invention relates to a hydraulic unit for a heating or air-conditioning system, which has at least one pump unit. Background technique [0002] Such a structural or housing unit for a heating installation is known, for example, from EP 2397777 A1. The structural unit has a circulation pump for conveying the heating medium and a heat exchanger, in particular for heating the domestic water. Furthermore, a switching valve is provided in order to switch the circuit for the heating medium between the heat exchanger and the connected heating circuit. Depending on the position of the switching valve, the pump unit can thus convey the heating medium, in particular water, either through the heat exchanger for heating the domestic water or through the connected heating circuit of the building. Furthermore, the structural unit has connections for connection to a heat source, in particular a primary heat exchanger of a heating boiler, by means of which the h...
