Hose for conveying refrigerant

A hose for conveying a refrigerant, the hose comprising:

• an inner surface layer and an outer surface layer disposed coaxially;
• and a reinforcing layer layered coaxially in between the inner surface layer and the outer surface layer,
• the inner surface layer comprising a thermoplastic resin composition or a thermoplastic resin, the thermoplastic resin composition having a sea-island structure comprising a matrix containing a thermoplastic resin and a domain containing an elastomer,
• the outer surface layer comprising a thermoplastic resin composition having a sea-island structure comprising a matrix containing a thermoplastic resin and a domain containing an elastomer,
• an oxygen permeability coefficient at a temperature of 21° C. and a relative humidity of 50% of the thermoplastic resin composition or the thermoplastic resin constituting the inner surface layer being 0.05 cm3·mm/(m2·day·mmHg) or less,
• a water vapor permeability coefficient at a temperature of 60° C. and a relative humidity of 100% of the thermoplastic resin composition constituting the outer surface layer being 10.0 g·mm/(m2·24 h) or less, and
• the reinforcing layer comprising an organic fiber, and an inclination angle of the organic fiber with respect to a hose axial center being set to 49° or more and 61° or less.
