Document Type and Number:
WIPO Patent Application WO/2024/099299
Kind Code:
A1
Abstract:
Provided in the present invention are a compressor control method and a compression system. The compressor control method comprises: acquiring the discharge pressure of a compressor; and according to the discharge pressure, dynamically controlling working modes of a variable-frequency compression unit and a fixed-frequency compression unit, so as to adjust the displacement of the compressor, wherein the working modes at least comprise a stop working mode, a loading working mode and an unloading working mode, and the variable-frequency compression unit and the fixed-frequency compression unit are separately connected to an oil-gas separator, such that compressed gas is supplied to the oil-gas separator by means of cooperation of the variable-frequency compression unit and the fixed-frequency compression unit. The described method adjusts the compressor displacement by means of controlling the working modes of the variable-frequency compression unit and the fixed-frequency compression unit, thus making the displacement adjustment mode more flexible, and expanding the displacement adjustment range.
