In order to develop a distributor for small-diameter air conditioner with a best distribution performance
a CFD model was established and experiments with air and water as working fluids were done to evaluate distribution performance of three types of commonly used distributors. The CFD model was validated by the experiments
the structure of the chosen distributor was optimized
and the optimized distributor was verified by its application in a room air conditioner. The results show that
the jack-type distributor has the best distribution performance
and its uneven index are less than 6% under rated cooling and rated heating conditions; the CFD model can predict the performance of distributors
with the deviation of uneven index less than 15%. The validated CFD model was used to optimize the structure of the jack-type distributor. Application of the optimized distributor shows that it can enhance the energy efficiency of room air conditioner by 2.2%~ 2.7%.
