Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/088034
Kind Code:
A1
Abstract:
This refrigeration cycle device is provided with pressure pulsation reduction units (15b, 15c, 15d) that reduce pressure pulsation of a refrigerant in a gas-phase refrigerant path (15). One example of the pressure pulsation reductions units is a muffler (15b) that increases the cross-sectional area of the gas-phase refrigerant path and that is arranged between a hose (15a) and a differential pressure valve (16) in the gas-phase refrigerant path (15). Other examples of the pressure pulsation reduction units include resonators (15c, 15d) that form a resonance space and that are connected between the hose (15a) and an intermediate pressure port (11b) in the gas-phase refrigerant path (15).
