The AC-Box, when combined with a heat pump, is able to deliver both natural and active cooling.
In the case of natural cooling, excess heat is removed via the heating circuit into the relatively cool ground or groundwater. Electricity is required only for the circulation pumps.
In the case of active cooling, the heat pump works like a refrigerator. With the aid of the AC-Box, it reverses the inputs and outputs and channels chilled water via the compressor circuit into the interior, thereby cooling it.
The heat extracted from the building's interior can in turn be utilised, for example for DHW heating or to heat a swimming pool.
This means cooling and heating functions can be combined extremely effectively.
Unlike traditional heating appliances, heat pumps utilise renewable energy from the ground, sun, groundwater or air. They lower consumption of fossil fuels, conserve valuable resources and reduce CO2 emissions that damage the environment.
