Aircraft air conditioning piping structure and air conditioning system

摘要

PROBLEM TO BE SOLVED: To provide an aircraft air-conditioning piping structure capable of promoting mixing of temperature-controlled air flowing into a mixing chamber constituting an air-conditioning system and recirculated air, and an air-conditioning system including the same. .. SOLUTION: An air-conditioning piping structure 30 has a temperature-regulated air and a mixing chamber 3 for mixing temperature-controlled air obtained by an aircraft air conditioner 2 and recirculated air discharged from a pressurized compartment 40. Inflow recirculated air. In the air-conditioning piping structure 30, the first pipe 31R through which the temperature-regulated air flows, the second pipe 32R through which the recirculated air flows and is connected to the first pipe 31R, and the temperature-controlled air and the recirculated air merge. A flow path limiting portion 35 that provides resistance to at least one of the temperature adjusting air and the recirculated air is provided in the vicinity of the merging position 33R.
