Abstract
A refrigerant distributor includes an inlet pipe, a header pipe to which the inlet pipe has been connected and a plurality of refrigerant pipes connected to one end side of the header pipe which is opposite to the side that the inlet pipe is connected, below the inlet pipe in a vertical direction, and is configured such that a refrigerant which has flown into the header pipe through the inlet pipe is distributed into the plurality of refrigerant pipes. The header pipe is arranged such that a vertical upper side of the header pipe is inclined toward the one end side that the refrigerant pipes are connected. Thereby, it is possible to stably distribute the refrigerant to each refrigerant pipe while suppressing an increase in cost under flow rate conditions ranging from a rated operation condition to a low rotating speed operation condition.
