Abstract

Abstract: The air flow organization form and effect of air conditioning are important factors that affect human thermal comfort, and have always been the hotspots and difficulties in the field. In order to explore the air distribution effect of the split hanging air conditioner with cross flow fan under the refrigeration condition and optimize it, used Computational Fluid Dynamics (CFD) technology to carry out a full-scale simulation of the air distribution form of a split hanging air conditioner, studied the distribution of indoor velocity field and temperature field under different air volume conditions, and compared the numerical simulation results with the experimental results. The research results are as follows: the error between the simulation results of indoor temperature distribution and the test results is controlled within 10%, and the temperature error of 76.2% of the measuring points is within 5%. Has a good reference value for the development and optimization of new models, and the full scale simulation method used has a good prediction effect on the indoor air distribution effect of air conditioning.
