A new method for calculating the deviation of refrigeration capacity due to wind speed in an enthalpy difference laboratory air sampler

When the indoor side air enthalpy method is used to measure the cooling capacity of household air conditioner, the wind speed in the air sampler will have a certain influence on the accuracy of the ambient humidity, which will affect the measurement result of the refrigerating capacity of the measured machine. In order to control this influence within the minimum range, this paper, from the aspects of science, convenience and operability, through uncertainty analysis, measured data analysis and data fitting, gives the calculation formula of cooling capacity deviation at different wind speeds of the air sampler at the side return air outlet of the enthalpy difference room according to the wind speed, making it convenient for each testing laboratory to correct the measurement results after the experiment.
