GB/T 40703-2021 (English Version) PDF

Scope: This document specifies the system composition, design parameters, energy demand analysis, general equipment requirements, solar thermal collection system, thermal storage system, heating system, electrical and control system of the solar medium-temperature industrial heat utilization system (hereinafter referred to as the "system") , system security protection requirements. This document is applicable to solar systems that use liquid as the heat transfer medium, have a heat collection temperature greater than 100°C and less than 250°C, and provide thermal energy for industrial process heat. Solar medium-temperature heat utilization systems that provide civil process heat can be implemented with reference to this document.
