High radiation reflection and low heat storage.
By using aluminum slats tilted at 45°, the irradiation of the sensor during sunrise and sunset is reduced.
The artificial ventilation of the radiation shelter is provided by a brushless DC fan inside a white-coated aluminum tube with a diameter of 60 mm. The air velocity in the tube is approximately 1.5 m/s. This ensures precise measurements even in absolutely calm conditions.
The solar power supply allows for grid-independent ventilation of the radiation shelter with temporary storage for operation during the night hours.
The ventilation provided serves only for mixing and does not meet the requirements of psychrometrics.
The system has its own battery with charge controller and status display.
