Problems solved by technology
Generally, after the air conditioner has been in operation for a long time, impurities such as iron filings and copper filings will be generated in the system, and the impurities will flow along the refrigerant to the throttling device, resulting in blockage of the throttling device, preventing the refrigerant and lubricating oil from participating in the flow cycle normally. The refrigerant and lubricating oil flowing into the compressor are reduced, and the lack of lubricating oil leads to increased wear between the compressor cylinder and the rotor, which makes the internal temperature of the compressor too high, so that the lubricating oil in the compressor is cracked and decomposed due to high temperature, and finally causes After the motor runs for a long time, it burns due to excessive heat, which reduces the service life of the compressor and the system

Generally, after an air conditioner operates for a long time, impurities such as scrap iron and copper scraps are generated in a system, the impurities flow into a throttling device along a refrigerant, the throttling device is blocked, the refrigerant and lubricating oil cannot normally participate in flowing circulation, the refrigerant and the lubricating oil flowing into a compressor are reduced, and the abrasion between a compressor cylinder and a rotor is increased due to insufficient lubricating oil. According to a control method, whether a first throttling device of the system is blocked is preliminarily detected through step S1; the blockage of the first throttling device is reduced through the step S2; the refrigerant is made to impact the blockage of the first throttling devicein the reverse direction, and the blockage problem is solved through step S3; and whether the blockage problem is solved is finally detected through the step S4.
Description
technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a device and a control method for improving the reliability of the air conditioning system. Background technique [0002] The throttling device of the air conditioner system has the function of throttling and reducing pressure, which is very important for the normal operation of the air conditioning system. Generally, after the air conditioner has been in operation for a long time, impurities such as iron filings and copper filings will be generated in the system, and the impurities will flow along the refrigerant to the throttling device, resulting in blockage of the throttling device, preventing the refrigerant and lubricating oil from participating in the flow cycle normally. The refrigerant and lubricating oil flowing into the compressor are reduced, and the lack of lubricating oil leads to increased wear between the compressor cylinder and the rotor, which m...
