GB/T 4271-2007
AbolishedTest methods for the thermal performance of solar collectors
太阳能集热器热性能试验方法
Application Summary AI generated
This standard specifies the test methods for determining the steady-state and quasi-steady-state thermal performance of solar collectors, including efficiency, heat loss coefficient, and time constant. It is applied in the testing and certification of flat-plate and evacuated tube solar collectors used in solar water heating and space heating systems. The standard is primarily used by manufacturers, testing laboratories, and quality inspection agencies in China to evaluate product performance under controlled indoor or outdoor conditions.
