In order to solve the above problems, patent application publication No. CN108106277A discloses a gas-liquid separator for a highly efficient air-cooled chiller, referring to fig. 5 and 6 of the specification, in the application, an inlet pipe is arranged to make the refrigerant entering a horizontal cylinder as far as possible from an outlet pipe, so as to increase the distance of gas-liquid separation, and the bent inlet pipe makes the liquid in the refrigerant more easily deposit under the action of centrifugal force, thereby improving the efficiency of gas-liquid separation.
However, the technical scheme still has more defects in actual application;
firstly, because the gas-liquid separator is used as a circulating component of the gaseous refrigerant, various noises exist, and besides the noise generated by unsteady flow of the gaseous refrigerant and the lubricating oil, vibration noise of the wall surface of the cavity of the gas-liquid separator under the operation working condition is also a source of the noise. The gas-liquid separator is often subjected to vibration generated by the movement of the compressor under the operation condition, and the resonance of the gas-liquid separator is caused when the excitation frequency from the compressor is coincident with the natural frequency of the gas-liquid separator, so the generated noise becomes one of noise sources in a refrigeration system;
due to the design of the positions of the refrigerant charging valve and the liquid return device, in actual use, the arrangement of the relative positions of the liquid return device and the refrigerant charging valve leads to the reduction of the flow cross section of the fluid in the tank body, so that the variation range of sound pressure is gradually increased, the refrigerant flow is further unstable, and the pressure fluctuation range is large so that the pneumatic noise is maximum.
