Refrigerating cycle device, air conditioner, choke, and flow rate controller

摘要

In a refrigerating cycle incorporating a second flow controller having a throttle section, which is composed of an inlet noise eliminating space 19, an inlet side porous permeable member 20 communicating in a refrigerant flow direction, an orifice 23, an outlet side foamed metal 25, and an outlet noise eliminating space 27, and a multi-directional valve, a gas/liquid two-phase refrigerant is caused to pass through the throttle section.
