Abstract

The invention provides a pipeline connection assembly and an air conditioner with the same. The pipeline connection assembly comprises a connection pipe nut, a first pipe joint and a second pipe joint, wherein the connection pipe nut comprises a first internal thread section located at the first end, a second internal thread section located at the second end, and a cylindrical outer surface, and a first connected pipe fitting is installed on the connection pipe nut; the first pipe joint comprises a force application section and a first external thread section, the first external thread section is matched with the first internal thread section, and a second connected pipe fitting is installed on the first pipe joint; the second pipe joint is arranged on the first connected pipe fitting in a sleeved mode and comprises a pipe joint body and an auxiliary nut, and the first pipe joint is provided with a first axial through hole enabling the first connected pipe fitting to be communicated with the second connected pipe fitting. According to the pipeline connection assembly, demounting prevention of connection pipes can be truly achieved, the problem that refrigerants are leaked due to disassembling of existing pipelines after being connected is solved, and pipeline connection can be more compact; after-scale installation and maintenance cost is reduced, and the use range of flammable refrigerants is enlarged.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a pipeline connection assembly and an air conditioner having the same. Background technique [0002] At present, the indoor and the indoor side of split-type air conditioners with ordinary working fluids use pipe joints and union nuts to connect the connecting pipes of the evaporator and the connecting pipes of the outdoor unit. The outer surface of the existing union nut is a prismatic surface with a force-applying cut surface. The pipe joint is generally an integral pipe joint, which is mainly composed of two parts: a threaded section and a prismatic surface section. When a clockwise torque is applied to the prismatic surface section, the thread The section rotates with the prism surface section and can be tightly matched with the union nut; however, when a counterclockwise torque is applied to the prism surface section, it also drives the thread section to rotate toge...
