The solar wall in the Energy Flow Wall is delivered in wood and aluminium.
The outer aluminium part encloses a 2-layer thermal glass with a sandblasted appearance to obscure the PCM containers behind.
In the case that the PCM containers or the electronics in the solar wall need to be serviced, the external 2-layer thermal glass is easily removable.
Behind the glass, the PCM container is attached to the back wall, which separates the insulation from the room containing the PCM containers.
At either the bottom or top of the solar wall is a fan that receives air from the outside and both blows and extracts the air into a manifold that distributes the fresh air across the entire width of the solar wall.
If the solar wall is to be placed on the outside wall of the building, the solar wall's edges are also delivered covered in aluminium.
At the top of the solar wall is the multifunctional valve which controls the airflow through the solar wall, which opens and closes on demand from the control panel.
In the solar wall, there are containers with PCM (Phase Change Material).
The containers are designed to make optimal use of the sun's rays, whereby the PCM heats up in a short time and stores the heat from the sun for night use.
In the containers, there may be a pipe system so that the heat from the PCM can be transferred with water into the building or to a heat storage tank.
The same pipe system can be used to cool the PCM by connecting it to, for example, a pipe system outside in the ground where there is a constant low temperature.
The PCM’s storage of heat from the sun during the day ensures that the sun's heat is used at night, which is the coldest part of the day.
The PCM's functions are:
In the horizontal top frame of the solar wall, the PCM, is a patent-pending multifunctional valve that is electronically controlled and acts together with the building's energy and indoor climate management.
The same valve is used at the top of the ventilation window.
Those valves regulate the air change in each room
The functions of the multifunctional valve in the top of the solar wall and the ventilation window are:
The functions of the multifunctional valve at the top of the ventilation window are:
At either the bottom or top of the solar wall, a fan in connection with a manifold.
The fan is electronically connected to the indoor climate and energy management of the building.
The fan blows and extracts fresh air from the outside into the manifold that has the entire width of the solar wall.
The fan's functions are:
