Abstract

The application relates to the field of refrigeration, and in particular relates to an air conditioning tube. The air conditioning tube comprises a discharge side tube and an absorbing side tube. The discharge side tube connects an exhaust port of a compressor to a joint end of a condenser, while the absorbing side tube connects an air absorbing port of a liquid storage device of the compressor to a joint end of an evaporator. The discharge side tube and the absorbing side tube respectively consist of first tube sections, middle tube sections and second tube sections which are sequentially butt-welded through flash welding or butt-welded through friction welding. The first and second tube sections are copper tube sections. The middle tube section is a non-copper tube metal section. Except for the tube sections for connection at both ends are not changed and are copper tube sections, the middle tube sections of the air conditioning tube are non-copper tube metal sections which are relatively low in cost and do not affect the performance of an air conditioner. Therefore, a lot of copper tube in the middle is saved, and meanwhile, the performance of the air conditioner is not affected, and the manufacturing cost is greatly lowered.
