All the measures have uncertainty and error.The uncertainty and error of solar heat gain test facility were analyzed in this paper
the uncertainty of each parameter and the influence degree to measuring results were gained
the uncertainty of fan-coil unit heat transfer and the influence degrees of fan-coil unit inlet and outlet water temperature to the measuring results were the biggest.The results showed that 95% of the testing error was within 7.6%
the biggest testing error was about 110 W
and the precision of the test facility met the testing requirement.
