Problems solved by technology

In actual operation, due to the different lengths of pipelines between the two compressors, or not working 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 that the moving parts 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.

[0072] Such as Figure 4 , Figure 5 with 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 ...

Embodiment 3

[0080] Such as Image 6 with 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 oil balance method for an air conditioner. The air conditioner comprises at least two compressors in parallel and an oil separator. Each compressor is provided with an oil balance pipe connected with an inlet of the oil separator. An exhaust port and an air inlet of each compressor are connected with the inlet and a second outlet of the oil separator respectively. The oil balance method comprises the following steps: step 1, the state of fluid in the oil balance pipe of each compressor is detected; step 2, when the fluid in the oil balance pipe of one compressor is lubricating oil and the fluid in the oil balance pipe of the other compressor is gas or a gas-oil mixture according to the detection in the step 1, the oil separator is controlled to supply oil to the compressor containing the gas or the gas-oil mixture and stop supplying oil to the compressor containing the lubricating oil. According to the oil balance method for the air conditioner, the oil level of the lubricating oil in each compressor is guaranteed, the phenomenon that the oil levels of the compressors in parallel are unbalanced is avoided, and therefore the service life of the compressors and the service life of the air conditioner are prolonged.

Description

technical field [0001] The invention relates to the technical field of oil balance, in particular to an oil balance method for 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] However, in the field of small and medium-sized commercial air conditioners, multi-connected air conditioners are often the main type, and there are usually two or more compressors connected in parallel in one outdoor unit. In actual operation, due to the different lengths of pipelines between the two compressors, or ...
