Abstract
In order to develop a distributor with excellent distribution performance under APF (Annular-performance factor) index, an assessment method of distribution performance has been proposed, and CFD simulations of flow distribution characteristic of three distributors, including jack-type, cone-type, reflective-type distributor in different installation angles have been carried out. Besides, the structure optimization of distributor under APF index is proposed under actual installation condition. The research result shows that, under APF index, the cone-type distributor is proved to have a best distribution performance for indoor unit, and the movement of chamber inside and the proper increase of angle between different branches could contribute to a more even better distribution; for outdoor unit, the reflective-type distributor is proved to have a best distribution performance, and the increased insertion length of inlet and the appropriate shortening length of connection tube between chamber and inlet could also contribute to a even better distribution.关键词
