Definitions

  • the present invention relates to a field of air conditioning technology, in particular, to a gas-liquid separator, a compressor assembly, and an air conditioner.
  • a compressor utilizes an intake pressure boost effect. Since the compressor periodically draws gas from a gas-liquid separator, refrigerant in the gas-liquid separator forms periodic pulsation. When a pulsation frequency of the refrigerant reaches an intake resonance, an amplitude of the pulsation of the refrigerant in the gas-liquid separator reaches the maximum.
  • the intake frequency of this type of compressor is equivalent to the intake resonance frequency (the intake frequency of the compressor is generally not greater than the intake resonance frequency), a pressure wave generated by the resonance of the refrigerant produces the intake pressure boost effect on the intake of the compressor, which in turn increases the amount of refrigerant sucked into the compressor, and enhances the compression performance of the compressor.
  • Document JP 2014092078A discloses a compressor in which an accumulator is fixed to the casing of the compressor body.
  • KR20180106790A discloses a gas-liquid separator according to the preamble of claim 1.
  • C denotes a speed of sound transmitting in the refrigerant (m/s)
  • L denotes a length of an outlet pipe through which the refrigerant flows (m)
  • V denotes a displacement of the compressor (m 3 )
  • A denotes a cross-sectional area of the outlet pipe (m 2 ).
  • the conventional compressors are developing toward higher and higher compression frequencies. That is, the intake frequency of the compressor is getting higher and higher, which causes the intake frequency of the compressor to exceed the intake resonance frequency, resulting in that the compressor cannot use the resonance pulsation of the refrigerant to achieve the intake pressure boost effect during the gas suction. Therefore, the amount of the intake in the compressor is reduced, resulting in the deterioration of the performance of the compressor.
  • the first-order resonance frequency f of the refrigerant may be increased by reducing the length L of the outlet pipe and the displacement V of the compressor, or increasing the cross-sectional area A of the outlet pipe. Changes in the displacement V of the compressor and the cross-sectional area A of the outlet pipe have a relative small influence on the first-order resonance frequency f of the refrigerant.
  • the length L of the outlet pipe has a relative large influence on the first-order resonance frequency f of the refrigerant.
  • the outlet pipe generally passes through a bottom of the gas-liquid separator, lessening the length of the outlet pipe means that the length of the gas-liquid separator should be also shortened, and thus the capacity of the gas-liquid separator will be reduced, which means the function of the gas-liquid separator will be weaken, causing the possibility of the compressor suffering from liquid hammer to be increased, affecting the performance of the compressor.
  • a Chinese patent with publication No. CN205349734U describes a technical solution in which an outlet pipe passes through a side wall of a housing of a gas-liquid separator to reach the outside of the housing, so that only the length of the outlet pipe is shortened without shortening the length of the gas-liquid separator, thus not affecting the capacity of the gas-liquid separator.
  • outlet pipe passes through the side wall of the housing of the gas-liquid separator to reach the outside of the housing, most of the outlet pipe hangs and extends into an inner cavity of the gas-liquid separator, thus causing the outlet pipe to easily produce a relative great vibration when the compressor is operating, causing an increasing in the noise easily, and even causing damage and fracture of the outlet pipe.
  • An objective of the present application is to provide a gas-liquid separator that can improve high frequency compression performance and facilitate the reflow of lubricating oil.
  • the present invention provides a gas-liquid according to independent claim 1. Further preferred embodiments of the invention are defined in the dependent claims.
  • the outlet pipe passes through the side wall of the housing of the gas-liquid separator to reach the outside of the housing.
  • the present application is beneficial to a lessening of the length of the outlet pipe and an increase in the first-order resonance frequency of the refrigerant, thus preventing the intake frequency of the compressor during high-frequency operation from significantly exceeding the first-order resonance frequency of the refrigerant, so that the first-order resonance frequency of the refrigerant in the gas-liquid separator can be equivalent to the intake frequency of the high-frequency compressor, which is convenient for the compressor to produce the intake pressure boost effect during high-frequency operation, thereby enhancing the intake efficiency of the compressor and improving the performance of the compressor.
  • the arrangement of the liquid suction pipe makes it easy for the lubricating oil at the bottom of the gas-liquid separator to be sucked into the compressor, thereby preventing a large amount of lubricating oil from being accumulated at the bottom of the inner cavity of the gas-liquid separator, enabling the compressor to be lubricated continuously, and ensuring a long-term reliable operation of the compressor.

  • the first outlet pipe includes an inner extension section and an outer connection section.
  • the inner extension section is disposed in the inner cavity of the gas-liquid separator.

  • the arrangement of the liquid suction pipe makes it easy for the lubricating oil at the bottom of the gas-liquid separator to be sucked into the compressor, thereby preventing a large amount of lubricating oil from being accumulated at the bottom of the inner cavity of the gas-liquid separator, enabling the compressor to be lubricated continuously, and ensuring that the long-term reliable operation of the compressor.

  • the outer connection section 133 passes through a side wall of the tubular body 101 to reach the outside of the housing.
  • the outer connection section 133 is fixed to a casing of the compressor 200 by welding.
  • the outer connection section 133 is fixed to the tubular body 101 by welding.
  • One end of the liquid suction pipe 104 extends to a bottom of the inner cavity of the gas-liquid separator 100, and the other end of the liquid suction pipe 104 is connected to the outer connection section 133.
  • the outer connection section 133 passes through the side wall of the tubular body 101 to reach the outside of the housing, and the inner extension section 131 extends into the inner cavity of the gas-liquid separator 100, therefore the inner extension section 131 is not fixedly connected to the tubular body 101, thus resulting in that the inner extension section 131 is not fixedly positioned, so that the inner extension section 131 may break and be damaged due to vibration. Therefore, a fixing member 102 is fixedly attached to the tubular body 101. The fixing member 102 is disposed in the inner cavity of the gas-liquid separator 100.

Therefore, the intake frequency of the compressor during high-frequency operation is prevented from significantly exceeding the first-order resonance frequency of the refrigerant, so that the compressor can effectively use the intake pressure boost effect during high-frequency operation, thereby enhancing intake efficiency of the compressor and improving the performance of the compressor.

  • the fixing member 102 is fixedly connected to a second height position of the tubular body 101
  • the connecting member 500 is fixedly connected to a third height position of the tubular body 101. Since the first height position and the third height position of the tubular body 101 are fixedly connected to the casing of the compressor 200, an area between the first height position and the third height position of the tubular body 101 has better anti-vibration performance.
