Solar Thermal Training System is a small model of real time water heating system and can be used for the characterization and different heat transfer analysis. Different aspects like efficiency, overall heat loss coefficient and heat removal factor and their corresponding calculations can be demonstrated with the help of this system. Special feature of this system is to perform experiments with different wind speeds, different fluid temperatures and different flow speeds. This system can be divided in three parts viz. main collector system, measuring unit and artificial light unit.
Main Collector system consists of a Flat Plate collector with temperature, flow and pressure sensors to measure temperature, flow and pressure of fluid. Measuring unit consists of a measurement panel displaying different parameters and Artificial light unit/ heat generating unit is a Halogen lamp panel to uniformly illuminate the flat plate collector inside a Lab. Artificial Light facilitates a user to do his/her work without depending on climatic changes in the environment.
Modular and scalable design of the system allows user to move the system in and out of lab easily and conduct experiment with artificial lights as well as actual sunlight. Using the system, a user will be able to study and understand working and operation of a flat plate collector water heating system and its two modes of operation.
