Solar Heat

Solar cooling

When using solar thermal systems to generate the heat for solar cooling of buildings, the other side of the coin is taken into account almost without noticing. Where there is solar heat, there is also a demand for cooling. In summer, when solar heat is available in abundance, we need cooling. In turn, this means that we can do away with buffer storage or keep them as small as possible while planning larger solar thermal systems. Thus, the systems can be designed more efficiently avoiding stagnation caused by a low heating demand in the summer. In winter, when there is no need for cooling, the solar heat can be fed directly into the heating system. Thus, the energy costs can be reduced, which would not be the case if solar energy were used exclusively for cooling.
