Scope

This document provides the measurement instruments, test platforms, test conditions, test preparations, test steps, heat loss coefficient calculation, and inspection reports for the heat loss coefficient of trough solar collector tubes.
This document is applicable to the steady-state heat balance method for testing the heat loss coefficient of trough solar collector tubes in parabolic trough solar thermal power generation systems and trough solar collector systems. The test of the heat loss coefficient of solar collector tubes in other linear Fresnel solar thermal power generation systems and linear Fresnel solar collector systems shall be carried out in accordance with this document.
