Problems solved by technology
[0002] In the existing air conditioning equipment system, the oil supply pipeline switch from the oil separator back to the compressor is controlled by the oil return solenoid valve, but it is not known whether there is oil in the oil separator, that is, there is no feedback control
Therefore, even if other control parameters are normal, it is impossible to judge whether the oil return is normal, whether the compressor is really running out of oil, and eventually the compressor will often be damaged.

Embodiment Construction
[0026] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0027] Such as figure 1 As shown, the air conditioning system includes a compressor 1 , an oil separator 2 , an outdoor heat exchanger 3 , a throttling component 4 , an indoor heat exchanger 5 , and a gas-liquid separator 6 arranged in sequence. , the suction port of the compressor 1 communicates with the gas-liquid separator 6 through the compressor suction pipeline 7 , and the gas outlet of the compressor 1 communicates with the inlet of the oil separator 2 through the compressor gas outlet pipeline 13 . After the oil separator 2 separates the lubricating oil from the mixture of the refrigerant and the lubricating oil, it is delivered to the compressor suction line 7 through the oil supply p...

The invention provides an air conditioner oil supply system and method, and an air conditioner. The air conditioner oil supply system comprises an oil separator, a plurality of oil supply pipelines and at least one oil supply detection part, wherein the oil separator is provided with a plurality of oil outlets; inlet ends of the oil supply pipelines are respectively communicated with the oil outlets; and each oil supply detection part is arranged on one oil supply pipeline, and used for detecting whether lubricating oil exists in the corresponding oil supply pipeline. According to the technical scheme provided by the invention, the plurality of oil supply pipelines are led out of the oil separator, and the existence of the lubricating oil in the oil supply pipeline can be detected to judge whether the oil level in the oil separator is higher than the oil outlet of the oil separator connected with the oil supply pipeline, thereby implementing the function of detecting the oil level in the oil separator.
Description
technical field [0001] The invention relates to the field of refrigeration equipment, in particular to an oil supply system of an air conditioner, an oil supply method and an air conditioner. Background technique [0002] In the existing air conditioning equipment system, the oil supply pipeline switch from the oil separator back to the compressor is controlled by the oil return solenoid valve, but it is not known whether there is oil in the oil separator, that is, there is no feedback control. Therefore, even if other control parameters are normal, it is impossible to judge whether the oil return is normal, whether the compressor is really running out of oil, and eventually the compressor will often be damaged. Contents of the invention [0003] The main object of the present invention is to provide an oil supply system of an air conditioner capable of detecting the oil level of an oil separator, an oil supply method and an air conditioner. [0004] In order to achieve t...
