Abstract
The invention relates to the field of a refrigerating system, and particularly relates to a technology of an air conditioner flexible pipe. A synthetic material air conditioner flexible pipe disclosed by the invention comprises an outer layer, an enhancement layer, a compensation layer, a separating layer and a buffer layer from outside to inside in sequence. The synthetic material air conditioner flexible pipe has flexibility of an automobile air conditioner flexible pipe, and has a separating property comparable to a copper pipe at the same time. By adopting the synthetic material air conditioner flexible pipe, use of a strategic metal copper can be reduced, and the synthetic material air conditioner flexible pipe has the advantages of low investment cost, recoverability and the like.
