Abstract
A hose for conveying a refrigerant having an inner surface layer that includes a thermoplastic resin composition with a sea-island structure or a thermoplastic resin, an outer surface layer that includes a thermoplastic resin composition having a sea-island structure, and a reinforcing layer. 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 of the inner surface layer is 0.05 cm·mm/(m·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 of the outer surface layer is 10.0 g·mm/(m·24 h) or less. The reinforcing layer includes an organic fiber with an inclination angle of 49° or more and 61° or less.
