Principles of Solar Thermal Energy

Description of Principles of Solar Thermal Energy

Solar thermal systems convert solar energy into usable thermal energy. It allows you to demonstrate solar thermal heating of domestic water in an illustrative manner. A lighting unit simulates natural solar radiation and allows a range of experiments to be carried out in the laboratory. The light is converted into heat in an absorber and transferred to a heat transfer fluid. A pump conveys the heat transfer fluid through a hot water tank. The heat is released to the water by an integrated heat exchanger in the tank.

It can be used to study a variety of angles of incidence and different illuminance. The pre-installed absorber with selective coating can be replaced for a more simple blackened absorber, so as to obtain comparative measurements of collector losses. External heat consumers can be attached to the tank via two connectors.
