Abstract: By evaluating and analyzing the uncertainty of the measurement of cooling capacity by air enthalpy method, the key influencing factors in the test process can be identified and the reliability of the test results can be determined. It can be seen from the analysis that the uncertainty component introduced by inlet and outlet wet-bulb temperature has the greatest influence on the results. It is very important to improve the precision of wet-bulb temperature measuring element and ensure the stability and reliability of wet-bulb temperature sampling.
