Vibration damping pipe of air conditioning system and air conditioning system

Abstract

The invention discloses a vibration damping pipe of an air conditioning system and the air conditioning system. The vibration damping pipe of the air conditioning system comprises a corrugated pipe, a protecting net cover, an expansion pipe, a first connecting pipe, a first connecting assembly, a second connecting pipe and a second connecting assembly. The expansion pipe is provided with an opening end; the first connecting pipe communicates with the expansion pipe, and the cross section area of the first connecting pipe is smaller than the average cross section area of the expansion pipe; the first connecting assembly comprises a first inner ring and a second outer ring; one end of the first inner ring is connected with one end of the corrugated pipe and fixedly welded, and the other end of the first inner ring is connected with the opening end and fixedly welded; one end of the protecting net cover is fixed between the first outer ring and the first inner ring through the first outer ring; and the second connecting assembly comprises a second inner ring and a second outer ring. According to the vibration damping pipe of the air conditioning system, the vibration excitation level can be reduced in two aspects of flowing and mechanical vibration of refrigerants.

Description

technical field [0001] The invention relates to the technical field of refrigeration devices, in particular to a shock absorber tube of an air-conditioning system and the air-conditioning system. Background technique [0002] During the cooling and heating operation or start-stop process of the air conditioner, the return air pipe and the enthalpy-increasing injection pipe connected to the compressor usually vibrate violently, and the mechanical vibration of the compressor body is only one of the vibration excitations of the return air pipe and the enthalpy-increasing injection pipe. One, in addition, the compressor intermittently sucks in refrigerant from the return air pipe and the enthalpy injection pipe, which will cause two effects: one is the pulsation of the internal static pressure of the return air pipe and the enthalpy injection pipe, and the other is the flow rate of the refrigerant Viscous force pulsation on the wall due to pulsation and discontinuous impact at t...
