Problems solved by technology

However, the above method still has the disadvantages of being able to reconcile the mismatch of the refrigerant cycle, and the throttle valve adjustment is lagging or poor in regulation, which will cause the unit to run with liquid and run out of oil quickly and shut down due to failure.
[0004] In the related technology, after detecting the presence of liquid in the compressor, the energy adjustment of the compressor is directly adjusted, but there are defects of misoperation and low control accuracy, which still cannot effectively solve the above technical problems

Embodiment 1

[0061] figure 1 A schematic flow chart showing the operation control method of the first embodiment of the present invention, such as figure 1 shown, including:

[0062] S102. Obtain the operating parameters of the compressor, and calculate the variation of the operating parameters within the first time period;

[0063] S104. Adjust the compressed gas volume of the compressor according to the change amount of the operating parameter within the first time period.

[0064] In this embodiment, first obtain the operating parameters of the compressor, and calculate the change of the operating parameters of the compressor within the first period of time; then judge whether the liquid-carrying condition of the compressor is Has a tendency to deteriorate. When the liquid-carrying situation has a tendency to deteriorate, reduce the compressed air volume of the compressor, thereby alleviating the liquid-carrying situation of the compressor to a certain extent, and ensure the stable o...

Abstract

The invention provides an operation control method, an operation control system, a computer readable storage medium, a compression system and an air conditioner system, wherein the operation control method comprises the steps that operation parameters of a compressor are obtained, and the variable quantity of the operation parameters in the first duration is calculated; and according to the variable quantity of the operation parameters in the first duration, the compressed air quantity of the compressor is adjusted. According to the operation control method provided by the invention, the compressed air quantity of the compressor is adjusted based on the variation trend of the compressor with-liquid condition. Under the condition that the compressor with-liquid condition has a worsening trend, the compressor with-liquid condition is relieved in a compressed air quantity reduction mode, a higher precision requirement can be achieved, a misoperation condition is avoided, and stable operation of the compressor and the compression system is ensured.

Description

technical field [0001] The present invention relates to the technical field of compression, in particular to an operation control method, an operation control system, a computer readable storage medium, a compression system and an air conditioning system. Background technique [0002] For the screw unit of the vapor compression cycle, the lubricating oil that lubricates the compressor rotor circulates together with the refrigerant, passes through the primary oil separator of the compressor and the secondary oil separator in the system, and is released from the refrigerant The liquid lubricating oil separated from the lubricant is returned and stored in the compressor oil sump. Therefore, the main cause of oil leakage is liquid entrainment, which will reduce the separation effect of the oil separator, and too much lubricating oil will be incorporated into the refrigerant cycle, resulting in lack of oil and a large amount of refrigerant in the oil pool. [0003] The conventio...
