Based on the mathematical model of air enthalpy difference method to measure the uncertainty of cooling capacity, the enthalpy difference method is used to measure the uncertainty of air conditioning cooling capacity. By analyzing the contribution of each parameter to the uncertainty of cooling capacity, a method of reducing the uncertainty of cooling capacity measurement is proposed. At the same time, this paper presents a method to assess the component of uncertainty of complex functions, making the evaluation of uncertainty more convenient and reliable.
