Building-integrated cold water storage during the construction phase.

We dimension both sensible and latent storage systems for a wide range of potential applications in buildings or technical applications. For this purpose we use our simulation tools "Comsol Multiphysics", "Modelica" or "ColSim", among others. Depending on the requirements, we combine the various storage technologies into hybrid systems and thus are able to design storage systems specifically for a given load profile.
