Solar collector experimental device
We will conduct measurement experiments on solar thermal efficiency and heat loss regarding the use of renewable and environmentally friendly energy sources. Similar to devices used for residential heating or swimming pools, it consists of pipes arranged on a plate, a transparent acrylic cover, a portable frame with an angle adjustment mechanism, a mixing pump, a pressure relief valve, and a control unit. The back of the plate is treated with insulation to reduce heat loss. Cold water supplied from sources such as water mains passes through a flow meter and valve, is heated by the solar collector, and enters the pump. The hot water discharged from the pump mixes with the supplied cold water and heads back to the solar collector. The pressure relief valve operates based on the water supply pressure, releasing hot water to limit internal pressure. The control unit digitally displays the cold water flow rate, solar radiation, cold water temperature, inlet/outlet temperatures of the solar collector, and ambient temperature, clarifying the energy efficiency and heat loss of the solar collector. By using the optional (sold separately) data automatic collection system VDAS-B, various data can be collected in real-time to a PC (sold separately), allowing for the analysis of experimental results.
