The mathematical model of solar collector consists of external energy balance of absorber (heat transfer from absorber surface to ambient environment) and internal energy balance of absorber (heat transfer from absorber surface into heat transfer fluid).
The use of the design tool for parametric analysis coupled with economical calculations can provide optimisation of the solar collector construction. Heat loss from absorber through glazing to ambient environment for solar collectors with low-emissive absorber (emittance 0.05) is around 75 % of overall collector heat loss.
The solar collector system concentrates the low-density solar energy into high-density energy, which contains heliostats and tower. The receiver mounted on top of the tower converts the redirected solar beam to thermal energy. The thermal storage system (TSS) is used to store the heat energy.
A solar collector which uses double-walled-glass tubes with the gap being evacuated (high vacuum) as thermal insulation. A solar collector with a flat absorber sheet. Optionally, a flat cover (covered flat plate collector) and conventional back and side thermal insulation can be added to reduce thermal losses.
Computer modeling of solar thermal collectors is a principle approach for testing of new construction concepts and improvements in the development and design stage for developers and manufacturers. Virtual prototyping of solar collectors can save the investments into number of prototypes and foresee the collector performance in advance.
At the heart of the solar thermal collector is the absorber where the conversion from radiation into useful heat happens and which should be in close thermal contact with the heat removal or operating medium. The most simple collector consists only of an absorber with heat removal construction (e.g., polymeric absorber matts).
