MULTI-CIRCUIT HEATING OR COOLING SYSTEM HAVING A MULTIPLE-WAY MIXING VALVE AND DEVICE FOR OPEN-LOOP AND/OR CLOSED-LOOP CONTROL FOR A MULTI-CIRCUIT HEATING OR COOLING SYSTEM

摘要

The invention relates to a multi-circuit heating or cooling system (100), a device for open-loop and/or closed-loop control for multi-circuit heating or cooling systems (100), and a method for operating a multi-circuit heating or cooling system (100). The multi-circuit heating or cooling system (100) is designed with an unmixed heating circuit (103) and a mixed heating circuit (105) in such a way that a hot-water store (107a) can be integrated and the mixed heating circuit (105) can be operated with heat from the unmixed heating circuit (103) or from a heat source (101a). There is a priority circuit for the hot-water store (107a), for charging the hot-water store with heat from the heat source (101a). In addition, the multi-circuit heating or cooling system (100) has an especially simple design and is also economically constructed.
