Title:
REFRIGERATION CYCLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/038659
Kind Code:
A1
Abstract:
A refrigeration cycle apparatus is provided with a refrigeration cycle configured by connecting a compressor 10, a first heat exchanger 12, a throttle device 16, and a second heat exchanger 15 with refrigerant pipes and through which a refrigerant circulates. The refrigerant is a single refrigerant or a mixed refrigerant formed of a substance that causes a disproportionation reaction. The refrigerant pipes include a bend section 45. Either one of the first heat exchanger 12 or the second heat exchanger 15 acts as a condenser and the other one thereof acts as an evaporator. The bend section 45 is provided in either one of or both of a flow passage between the condenser and the throttle device and a flow passage between the throttle device and the evaporator. The bend radius R of the bend section 45 through which a liquid refrigerant or a two-phase refrigerant passes satisfies the following relationship:
R ≥ (d/2) × [1 + {tan(π/36) + cosθ}]/[1 - {tan(π/36) + cosθ}],
where θ (rad) denotes the angle formed between the center line of an inlet pipe configuring a refrigerant inlet side of the bend section 45 and the center line of an outlet pipe configuring a refrigerant outlet side of the bend section 45, R (mm) denotes the bend radius of the bend section 45, and d (mm) denotes the internal diameter of the inlet pipe of the bend section 45.
