The separation of the primary and secondary heating and cooling circuits brings a number of advantages to the residential tower. This allows the residents to adjust the room temperatures to their individual needs via the stations completely independently of the overall system, which significantly increases living comfort. The 6-way ball valve integrated in the decentralized solutions ensures that the consumers are reliably supplied with the required flow rate of hot or cold water at all times, both in heating and cooling mode.
In addition, by decoupling the residential units, the source of the fault can be identified relatively quickly in the event of a possible fault in the complex system. If this is located in the living area, the rest of the heating system remains fully operational during repair work. The stations also make it easy to retrofit a cooling ceiling or fan coil, as the necessary connections are already in place and the retrofit can be carried out without affecting the rest of the system.
At the same time, high pressures in the risers are required for reliable power distribution in the complex, which are reliably compensated by the dwelling stations. For this purpose, the manufacturer had extensive tests carried out with the tubes of the solutions in order to have them certified for nominal pressures up to PN 25. In addition, dynamic pressure closed-loop controllers are used to reduce the system pressure (PN 16) to the optimum level for the secondary circuits when it is transferred to the heating circuits.
