  • FIG. 1 shows a structure diagram of a condenser known to the inventors.
  • an air conditioner condenser known to the inventors includes a housing 1, and an inlet 2 and an outlet 3 disposed on the housing 1. Both the inlet 2 and the outlet 3 are disposed on a first end of the housing 1.
  • the condenser further includes a first pipeline and a second pipeline disposed in the housing 1. A first end of the first pipeline communicates with the inlet 2, a first end of the second pipeline communicates with the outlet, and a second end of the second pipeline communicates with a second end of the first pipeline.
  • the first pipeline is disposed in the first hole in a penetrating manner
  • the second pipeline is disposed in the second hole in a penetrating manner.
  • first pipelines There are a plurality of first pipelines, and all the first ends of the plurality of first pipelines communicate with the inlet 2.
  • second pipelines There are a plurality of second pipelines, and all the first ends of the plurality of second pipelines communicate with the outlet 3.
  • the oil separator 4 is on the inner top of the housing 1 of the condenser.
  • Fig. 2 shows a structure diagram of a oil separator known to the inventors.
  • the oil separator includes a chamber.
  • a gas inlet 7 for introducing a refrigerant to be separated and a gas outlet 6 for outputting the separated refrigerant are disposed on the chamber.
  • the gas inlet 7 and the gas outlet 6 are arranged on a same side face of the chamber. In some embodiments, both the gas inlet 7 and the gas outlet 6 are disposed on an upper end of the chamber.
  • An exhaust port of a compressor communicates with the gas inlet 7 of the oil separator 4.
  • the refrigerant separated by the oil separator 4 is discharged from gas outlet 6 to the inner cavity of the housing 1 of the condenser, and performs heat exchange with a medium in the first pipeline and the second pipeline.
  • a width of the chamber shrinks along the direction away from the gas outlet 6.
  • An end, away from the gas outlet 6, of the chamber is provided with an oil drainage port 9 for draining an oil separated from the refrigerant.
  • the refrigerant changes a flow direction after entering the chamber through the gas inlet 7, and finally flows out from the chamber of the oil separator 4 through the gas outlet 6.
  • the oil is separated from the refrigerant under the inertia effect.
  • filtering performance of the filter component 8 is designed by the standard of a requirement of the area with the maximum pressure of airflow. Therefore, in the area with the relatively low pressure of airflow, the performance of the filter component 8 causes an unnecessary waste, and the filter component in the area produces unnecessary resistance to airflow. Therefore, the filter component 8 with single performance arranged at the outlet of the oil separator 4 is an unnecessary waste for the area with relatively low pressure of airflow, and causes an airflow blockage to the area with relatively low pressure of airflow.
  • Some embodiments of the disclosure provide an air conditioner oil separator, a condenser and an air conditioner, to alleviate a problem in an air conditioner oil separator known to inventors that a filter component with single performance is not adaptable to requirements of areas at different distances from an inlet.
  • the air conditioner oil separator includes a gas inlet for introducing a refrigerant to be separated, a gas outlet for outputting a separated refrigerant, and a filter component disposed at the gas outlet.
  • the filter component includes:
  • the separation efficiency of the third filter area for the refrigerant is higher than a separation efficiency of the first filter area for the refrigerant.
  • the gas outlet includes a first gas outlet and a second gas outlet respectively at two sides of the gas inlet.
  • both the gas inlet and the gas outlet are disposed on a top of the air conditioner oil separator.
  • the first filter area, the second filter area and the third filter area are arranged side by side in a direction close to the gas inlet.
  • the condenser includes:
  • the pipeline includes:
  • first pipeline and the second pipeline are respectively disposed at two sides of the air conditioner oil separator.
  • Some embodiments of the present disclosure provide an air conditioner, the air conditioner includes:
  • the problem of waste caused by excess capacity of the filter component is alleviated, and it is beneficial to uniformity of gas pressures in different areas of the gas outlet.
  • Fig. 3 illustrates a structure diagram of an air conditioner oil separator according to an embodiment.
  • Fig. 4 illustrates a partial enlarged drawing of an air conditioner oil separator according to an embodiment.
  • the air conditioner oil separator of some embodiments includes a chamber 1, a gas inlet 2 disposed on the chamber 1 and a gas outlet disposed on the chamber 1.
  • the gas inlet 2 and the gas outlet are arranged on a same side face of the chamber 1.
  • the gas outlet is provided with a filter component 3.
  • the filter component 3 is configured to filter oil mixed in a refrigerant.
  • the gas outlet extends in a length direction of the oil separator.
  • the gas outlet includes a first gas outlet and a second gas outlet respectively disposed at two sides of the gas inlet 2, to shorten a length of each gas outlet, thus a pressure difference of airflow between the two gas outlets is reduced.
  • the air conditioner oil separator further includes a baffle 4 disposed in the chamber 1.
  • the baffle 4 is opposite to the gas inlet 2. After entering the chamber 1, the refrigerant to be separated first impacts with the baffle 4. After the refrigerant to be separated impacts with the baffle 4, because oil and gaseous refrigerant have different inertias, the oil and the gaseous refrigerant are separated for the first time.
  • the refrigerant mixed with less oil moves to the two sides of the gas inlet 2, and then enters the condenser after being filtered by the filter component 3, and performs heat exchanger with other media in the condenser.
  • the performance of the filter component 3 is a separation efficiency of the filter component, namely a ratio between oil content of the refrigerant before passing through the filter component 3 and oil content of the refrigerant after passing through the filter component 3.
  • the separation efficiency of the filter component 3 is also related to the material of the filter component 3.
  • the performance of the filter component 3 with single performance is often designed to the highest requirements.
  • the filter component 3 of some embodiments includes a first filter area 31, a second filter area 32 and a third filter area 33 sequentially disposed in a direction close to the gas inlet 2.
  • the third filter area 33 is close to the gas inlet 2.
  • the third filter area 33 is also a filter area closest to the gas inlet 2 of multiple filter areas.
  • a separation efficiency of the first filter area 31 for a refrigerant is lower than that of the second filter area 32 for a refrigerant
  • the separation efficiency of the third filter area 33 for a refrigerant is lower than that of the second filter area 32 for a refrigerant
  • the separation efficiency of the third filter area 33 for the refrigerant is higher than that of the first filter area 31 for the refrigerant.
  • the performance of the filter component is fully used, and it is beneficial to ensuring the uniformity of the pressures of airflow output by various areas of the gas outlet.
  • the gas outlet with a length L is divided into the first filter area 31, the second filter area 32 and the third filter area 33. All the sizes, in the direction away from the gas inlet 2, of the first filter area 31, the second filter area 32 and the third filter area 33 are 1/3L.
  • the thicknesses and the materials of the filter components of the first filter area 31, the second filter area 32 and the third filter area 33 are the same.
  • the densities of the first filter area 31, the second filter area 32 and the third filter area 33 are respectively H 1 , H 2 and H 3 .
  • the separation efficiencies of the first filter area 31, the second filter area 32 and the third filter area 33 are respectively E 1 , E 2 and E 3 .

  • the densities and materials of the filter components of the first filter area 31, the second filter area 32 and the third filter area 33 are the same, but the thicknesses are different, so that E 2 >E 3 >E 1 .
