Solar thermal energy

Solar energy as a natural resource holds enormous potential. The annual solar energy irradiated onto the continents is about 5,000 times the global demand for primary energy. GUNT optimally supports the education of specialists towards utilising this potential in the future.

 


Fundamentals of solar thermal energy use

Solar thermal energy is defined as using solar power to provide heat. The heat can be used for heating in the home and for heating domestic water, as well as for process heat in industry and for steam generation in power stations and even for cooling.

Concentrating solar thermal energy

With concentrating collectors, the irradiation is multiplied optically by mirrors and lenses on the absorber. Since only the direct radiation portion can be concentrated, the use of such systems makes sense in regions with high direct irradiation.

ET 203 Animation Sonnennachführung

Azimuth and elevation tracking

The orbital and rotational movement of the earth causes the sun’s elevation and of the sun’s altitude (elevation) and orientation (azimuth). ET 203 can be tracked via two geared motors to track the position of the sun.

 

  • motorized two-axis tracking

  • sensor-based control or control according to calculated astronomical data

Operation and control

Operation and control are carried out via the integrated PLC and touch screen. By means of an integrated router, the trainer can alternatively be operated and controlled via an end device. The user interface can also be displayed on additional end devices (screen mirroring).

 

 


Solar thermal energy for domestic water heating

In a solar thermal collector, radiant energy is converted into heat and transferred to a heat transfer fluid in the solar circuit. The heat then gets into the hot water circuit via a heat exchanger.

Solar thermal energy in modular systems for domestic supply

Doing away with a conventional heating system represents a genuine alternative for modern residential buildings with good thermal insulation in many cases. The combination of solar thermal collectors with a heat pump very often guarantees significant savings with reliable year-round supply.

HL 320 Modular system

The HL 320 modular system allows experiments on the generation, storage and use of heat from renewable energies. The modular concept of the HL 320 system allows you to create a variety of configurations.
