The trough solar medium and high temperature collection system consists of a trough collector, a tracking control system, a PLC control center, an energy storage system and an energy consumption terminal.
The trough-type solar medium-high temperature collection system consists of a trough collector, tracking control system, PLC control center, energy storage system, and energy utilization terminal.
1.Technical Principle:
Sunlight is directed onto the parabolic curved glass, and through the reflective action of the curved glass, the sunlight is focused on the metal straight-through tube's metal absorber coating located at the focal point of the collector. The heat is efficiently absorbed by the metal absorber coating. Simultaneously, the collector, aided by the tracking system, dynamically tracks the sun's trajectory in real-time, maintaining the maximum heat absorption efficiency. The low-temperature working fluid flowing inside the metal straight-through tube is heated, and through heat exchange, the high-temperature working fluid transfers heat to the energy utilization terminal, achieving the purpose of solar thermal utilization.
