Oil distributing device for air conditioner

Abstract

The present invention discloses an oil separator of air conditioner. It includes external shell which is used for forming appearance, refrigerant discharge tube which is extended into the interior of external shell, one side of said refrigerant discharge tube is equipped with an oil-separating fan, the oil-separating fan is set in the interior of external shell, and can be rotated to produce vortex flow, the refrigerant in the external shell interior can be passed through the refrigerant discharge tube and discharged, the side face of the external shell is equipped with refrigerant supply tube, said refrigerant supply tube can supply refrigerant to the interior of the external shell, the oil-separating fan can be rotated by utilizing refrigerant discharged from refrigerant supply tube so as to separate the lubricating oil from refrigerant.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner oil separator. That is, the lubricating oil is recovered by utilizing the centrifugal force generated by the rotation of the oil separation fan. Background technique [0002] An air conditioner is a device that inhales hot air in the room, exchanges heat with it with a low-temperature refrigerant, and discharges the heat-exchanged air to the room. The air conditioner cools the room by repeating the process, or heats the air in the room by performing the reverse operation of the above process. The air conditioner is composed of compressor-condenser-expansion valve-evaporator, forming a loop. [0003] Recently, air conditioners having various additional functions such as an air filtering function and a dehumidification function have also appeared on the market. This air conditioner can take in indoor air from the outside, filter it, and discharge clean air. It can also d...

Problems solved by technology

Although the outdoor unit 1 of the air conditioner has an oil separator 12, the inside of the oil separator 12 has a mesh screen 12b or a metal filler, and is also provided with an upper plate 12c and a lower plate 12d etc. to filter lubricating oil, but Relative to the oil separation efficiency, the structure is too complicated

[0029] In addition, when the variable-speed compressor 10" is running at high frequency, the flow rate of the cold coal discharged from the variable-speed compressor is particularly high, so it is possible that the passing cold coal cannot be fully filtered

[0030] When the flow rate of the cold coal is too fast, the lubricating oil cannot be separated sufficiently, resulting in too much lubricating oil in the cold coal, which affects the heat exchange efficiency and reduces the performance of the entire air conditioner
