Project Binsdorf

The concept of the innovative heating system using Smirro GmbH is based on an interplay between seasonal latent heat storage, electrical heat pumps and parabolic troughs. The parabolic troughs provide for the necessary heat energy during the transitional seasons by loading two buffer storage units of each 1500 litres from which the floor heating system is fed.


In the Fall, when the sun's rays are no longer intense enough, the heating pumps serve themselves of the seasonal latent heat storage unit, with its massive storage volume of 800.000 litres of water, which makes the required heating energy available. The heating pumps take advantage of the high energy density that is created by the phase change of water between 0° in its liquid state and 0° in its solid state. On the sunny Winter days, the parabolic troughs can take over the heating.

In the Spring, the storage unit contains a huge quantity of ice. This reservoir can be used at any time for the cooling of the building. However, since the needed cooling power in the Summer is not as high as the potential energy stored in the ice, the 30 parabolic troughs send their energy in the Summer directly to the ice storage unit.

This ensures that, for the cold Winter days, the bundled quantities of energy of the phase change will again be made available as the cycle repeats itself.
