Domestic water heating with tube collector

Tube collectors have an empty glass tube as absorber and are therefore also called vacuum tube collectors. The vacuum reduces the heat losses, so that this type of collector achieves a higher degree of efficiency.

• investigating the function and operating behaviour of a tube collector
• solar thermal evacuated tube collector with selectively absorbing coating
• connection of absorbers by heatpipes
• adjustable collector inclination angle
• solar circuit with collector, pump, expansion vessel and safety valve
• hot water circuit with buffer tank, pump and plate heat exchanger
• 4 bimetallic thermometers
• solar controller with temperature, flow rate and illuminance sensors
• data logger with SD memory card
• integrated router for operation and control via web browser using an end device and for tracking experiments on any number of end devices
• experiment evaluation on Windows-based end devices possible, with additional producer software of the solar controller
• operation with solar radiation or artificial light source
