Problems solved by technology

In actual operation, due to the different lengths of the pipelines between the two compressors, or they do not work at the same time, the internal oil level of the first compressor may be too high, while the internal oil level of the second compressor is too low to ensure the operation of the components. lubrication
At this time, if no control measures are taken in the compressor and system control, the oil level of the oil-deficient second compressor cannot be restored to the normal oil level position, and there will be wear and tear of the moving pair in a short time or even the compressor will be stuck.

Embodiment 1

[0064] Such as figure 2 and image 3 As shown, in the embodiment of the present invention, the air conditioner 100 includes two first sensors 6a, 6b and one second sensor 7, and each first sensor is set at the oil balance pipe 40 of each compressor 4 and is separated from the oil On the second pipeline 15 between the inlet 30 of the oil separator 3, it is used to detect the fluid state in the second pipeline 15, and the second sensor 7 is arranged adjacent to the second outlet 32 ​​of the oil separator 3 to detect the flow from the second outlet 32 The fluid state of the outflow. In other words, the first sensor 6a is set on the second pipeline 15 between the oil balance pipe 40 of the first compressor 4a and the inlet 30 of the oil separator 3, and the first sensor 6b is set on the oil balance pipe 40 of the second compressor 4b. On the second pipeline 15 between the balance pipe 40 and the inlet 30 of the oil separator 3 , the first sensor 6 a and the first sensor 6 b are...

Embodiment 2

[0074] Such as Figure 4 , Figure 5 and Figure 8 As shown, in the embodiment of the present invention, the air conditioner 100 includes two first sensors 6a, 6b and one second sensor 7, and each first sensor is set at the oil balance pipe 40 of each compressor 4 and is separated from the oil The second pipeline 15 between the inlet 30 of the oil separator 3 is used to detect the fluid state in the second pipeline 15, and the second sensor 7 is arranged adjacent to the second outlet 32 ​​of the oil separator 3 to detect the flow out of the second outlet 32. fluid state. In other words, the first sensor 6a is arranged on the second pipeline 15 between the oil balance pipe 40 of the first compressor 4a and the inlet 30 of the oil separator 3, and the first sensor 6b is arranged on the oil balance pipe 40 of the second compressor 4b. On the second pipeline 15 between the pipe 40 and the inlet 30 of the oil separator 3 , the first sensor 6 a and the first sensor 6 b are used t...

Embodiment 3

[0082] Such as Figure 6 and Figure 7 As shown, the air conditioner 100 also includes two first sensors 6a, 6b and a fifth sensor 10, and each first sensor is arranged between the oil balance pipe 40 of each compressor 4 and the inlet 30 of the oil separator 3 The second pipeline 15 is used to detect the state of the fluid in the second pipeline 15, and the fifth sensor 10 is arranged adjacent to the inlet 30 of the oil separator 3 to detect the state of the fluid flowing into the oil separator 3. In other words, the first sensor 6a is arranged on the second pipeline 15 between the oil balance pipe 40 of the first compressor 4a and the inlet 30 of the oil separator 3, and the first sensor 6b is arranged on the oil balance pipe 40 of the second compressor 4b. On the second pipeline 15 between the pipe 40 and the inlet 30 of the oil separator 3 , the first sensor 6 a and the first sensor 6 b are used to detect the fluid state in the corresponding second pipeline 15 .

Abstract

The invention discloses an air conditioner, comprising: a condenser, an evaporator, an oil separator and at least two compressors, the exhaust port of each compressor is connected with the inlet of the oil separator, and the intake port of each compressor The ports are respectively connected with the second outlet of the oil separator and the evaporator, and each compressor is provided with an oil balance pipe connected with the inlet of the oil separator, when the lubricating oil in one of the at least two compressors When the oil level exceeds the predetermined height and the oil level of the lubricating oil in the other compressor of the at least two compressors is lower than the predetermined height, part of the lubricating oil in one compressor that exceeds the predetermined height enters the In the oil separator, and part of the lubricating oil in the oil separator enters another compressor. According to the air conditioner of the embodiment of the present invention, the oil level of the lubricating oil in each compressor is guaranteed, the phenomenon of oil level imbalance between parallel compressors is avoided, and the service life of the compressor and the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of oil balance, in particular to an air conditioner. Background technique [0002] In recent years, with the continuous improvement of the energy-saving level of air conditioners and the continuous popularization of frequency conversion technology, more and more variable frequency rotary compressors have appeared in light commercial and commercial air conditioning systems. With their relatively low processing costs and relatively wide The frequency range has the ability to replace the traditional digital scroll machine and frequency conversion scroll machine. [0003] In the field of small and medium-sized commercial compressors, multi-connected air-conditioning units are often the mainstay, and there are usually two or more compressors connected in parallel in one outdoor unit. In actual operation, due to the different lengths of the pipelines between the two compressors, or they do not work at the same ti...
