Puts forward an equivalence method to transform the dimension between parallel capillary tubes. Taking a 25 kW-refrigerating capacity air conditioner as an example, compares the dimension obtained by the equivalence method with that by the match experiment method. The results show that the difference of the inner diameter and length is separately 3.6% and 5.8%and that it is proved that the equivalence me...
