MULTI-CIRCUIT HEATING OR COOLING SYSTEM HAVING A BUFFER STORE, DEVICE FOR OPEN-LOOP AND/OR CLOSED-LOOP CONTROL FOR A MULTI-CIRCUIT HEATING OR COOLING SYSTEM HAVING A BUFFER STORE, AND METHOD FOR OPERATING A MULTI-CIRCUIT HEATING OR COOLING SYSTEM HAVING A BUFFER STORE

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) has a mixed heating circuit (105), such that a buffer store (103a) for storing heat is integrated and the mixed heating circuit (105) can be operated with heat from the buffer store or from a heat source (101a). A priority circuit for the buffer store (103a) charges the buffer store with heat from the heat source (101a), and the buffer store (103a) is integrated into a hot potable water processing means (107). In addition, solar thermal heat sources (157, 159) can be integrated, and the multi-circuit heating or cooling system (100) has an especially simple design and is also economically constructed.
