Distributor for a heating or cooling installation

摘要

The tunnel has fluid supply and return chambers with respective fluid supply and return connections (20, 20`) for fluid circulation. A switch chamber (3) with a larger horizontal length is connected with the connections. A moderate horizontal distance of fluid flow between the connections is calculated, which amounts to quadruple of nominal diameter of the connections and up to eighty percent of the horizontal length of chamber (3). The tunnel is welded with steel metal parts. The switch chamber has a mud outlet nozzle that is arranged between junctions of the fluid supply and return connections.
