Abstract (en)
Provided is a refrigeration cycle apparatus, including a refrigeration cycle through which refrigerant circulates, the refrigeration cycle being formed by connecting a compressor (10), a first heat exchanger (12), an expansion device (16), and a second heat exchanger (15) by a refrigerant pipe, the refrigerant including single-component refrigerant made of a substance having such a property as to cause a disproportionation reaction or a refrigerant mixture, the refrigerant pipe including a bent portion (45), one of the first heat exchanger (12) and the second heat exchanger (15) being configured to serve as a condenser and an other thereof being configured to serve as an evaporator, the bent portion (45) being provided to one or both of a passage between the condenser and the expansion device and a passage between the expansion device and the evaporator, in which a bending radius R of the bent portion (45) through which liquid refrigerant or two-phase refrigerant flows satisfies the following relationship: R ‰¥ d / 2 × 1 + tan À / 36 + cos¸ / 1 ˆ’ tan À / 36 + cos¸ , where ¸ (rad) represents an angle formed between a center line of an inlet pipe configured to form a refrigerant inlet side of the bent portion (45) and a center line of an outlet pipe configured to form a refrigerant outlet side of the bent portion (45), R (mm) represents a bending radius of the bent portion, and d (mm) represents an inner diameter of the inlet pipe of the bent portion (45).
