Regulated two-zone buffer storage for use in e.g. solar heat plant, has container divided into lower and upper chambers by circular blank, where heat exchangers are arranged in lower chamber that is formed in low temperature zone

摘要

The storage has a container that is divided into upper and lower chambers (3, 4) by a circular blank (2) which holds pipes. The upper chamber is formed in a high temperature zone and the lower chamber is formed in a low temperature zone. Heat exchangers (5-8) are arranged in the lower chamber, and deflectors (14, 15) are arranged above openings of the pipes, where the heat exchangers are connected with a district heating pipeline.
