20080251244 | Three Pipe System - The 3-pipe system is a new method of building closed hydraulic networks for heat transfer and fluid distribution. Generally, the new system can be applied in HVAC networks and ensures better and more stable network behaviour during flow adjustment. In other words, it ensures hydraulically balanced networks with optimal behaviour. The basic characteristic of the new three-pipe system is that the central distribution pipe is split into two, in which water flows in the same direction as in the central distribution pipe. Subsequently, the two pipes are joined in one, which is the return pipe. Thus, the pipes create a central loop, which includes the terminal units. The one part of the loop is the point where the terminal unit branches start and the other is where they end. Water flow is ensured by means of a local circulator, which compensates for pressure drop in the branch. In case of reverse flow in deactivated terminal units, a non-return valve is recommended for each terminal unit. The structure of the patent is demonstrated in FIG. <8>. The central distribution pipe <> is split into two pipes, <> and <>, in which water flow is also split. The two pipes are joined again in pipe <>, creating a closed loop. Water in pipes <>, <>, <> and <> flows in the same direction. The terminal unit branches are positioned inside the loop. Each local branch has got a circulator to compensate for water supply. There is also a central circulator, which supplies the central loop with water. | 10-16-2008 |
