Abstract Air-enthalpy method is commonly used in measuring cooling capacity of the air conditioner. Some uncertainty evaluation methods for measurement and corresponding mathematical models may exist because of the complex calculating formulas. Base on the formulas for calculating cooling capacity, the two kinds of mathematical models which indicated by intermediate variables and direct testing variables are established. With ten independent measurement data, the results of the two kinds of uncertainty evaluation of are obtained, and the differences between them are analyzed.

Key words： Metrology Cooling capacity Uncertainty Air-enthalpy method Intermediate variable Direct testing variable
