Central heating system with multiple way mixer valve has two independently operated heat sinks, with additional overflow valve switched in parallel and compensation path, for compensation of flow volume differentials

摘要

The device connects the connections (7,8) of a heat source (2) with circulation pump (27') and overflow valve (52). Two heat sinks are connected via the valve (20). A compensation path (55) is provided parallel to the second heat sink (22), and there is a further overflow valve (53) parallel to the first heat sink (21). There is also a pressure limitation valve parallel to the second heat sink, with the overflow valve parallel to the first heat sink. Mixer valve, compensation path, and additional overflow valve are combined in a modular unit (9). A heat exchanger (50) in the second heat sink contains a circulation pump (28').
