Layered buffer storage with mixing distributor

摘要

The storage has connecting minors for the boiler forward and return flow branches. There is a heating circuit return flow collector (9) with one or several mixing valves (10) and a bypass (8) directly on the buffer storage. The heating circuits with the lowest forward temp. are fitted below, and those with highest forward temp. above.The heating circuits lead away from the buffer storage which serves as a forward flow distributor. The rear flow (2) from the hottest, non-mixed heating circuit is fed to the forward flow of colder, mixed heating circuit by the bypass (7). The coldest return flows are directly fed to the boiler from the collector.
