Preparation and distributing of mixed or user water - has hot water preparation for storage system effected within high temperature stage via heat exchanger

摘要

The storage system (200) itself comprises several accumulators (201,202) which are connected via at least one conduit (203). At least one accumulator is charged layer-wise in the gravitation direction with high-grade hot water. This layer represents the reaction volume (202a), which makes available hot water of approximately 60 deg. C for the distribution and preparation stages (300,300a). Within the preparation stage is a heat exchanger (326), the primary side of which is flowed through by the hot water from the reaction volume. This hot water thereby experiences a cooling, so that where needed a direct mixing with hot water from the reaction volume takes place, whereby the user stage (400) is always fed with hot water of around 45 deg. C.
