Branch pipe and air conditioning system

摘要

A branch pipe (1) according to the present invention is provided for gas pipes for communicating at least one indoor unit and outdoor units, and used at a branch section for distributing refrigerant to the outdoor units. The branch pipe (1) includes an inflow portion (17) into which the refrigerant flows, a first outflow portion (18) for discharging the refrigerant flowing from the inflow portion (17) toward the outdoor units, and a second outflow portion (19) for discharging the refrigerant flowing from the inflow portion (17) toward the outdoor units different from the outdoor units that are outflow destinations of the first outflow portion (18) at a target flow rate different from a target flow rate of the first outflow portion (18), and the cross section ratio S1:S2 between the first outflow portion (18) and the second outflow portion (19) is determined depending on the target flow ratio between the first outflow portion (18) and the second outflow portion (19).
