Comparison of thermal losses due to heating-up of system components in two solar process heat plants with parabolic trough collectors

The work focuses on experimental analysis of two solar process heat plants with parabolic trough collectors quantifying daily and monthly inner energy ΔU required to heat-up heat transfer fluid and piping system and comparing it to useful solar energy gains Q_use.

The work focuses on experimental analysis of two solar process heat plants with parabolic trough collectors quantifying daily and monthly inner energy ΔU required to heat-up heat transfer fluid and piping system and comparing it to useful solar energy gains Q_use. Both plants analyzed provide solar heat for dairies and are located in northwest (Saignelégier) and southeast (Bever) of Switzerland. They operate at different collector temperatures (120 °C/190 °C) and differ in size (627 m²/115 m²), integration concept (hot water/steam) and type of heat transfer medium (water-glycol/thermal-oil).
