The invention provides a control method and device for air compressor compression work optimization and equipment and a storage medium. The control method comprises the steps that a controller determines a first-stage compression ratio corresponding to a first-stage inverter compressor unit according to a first-stage air inlet temperature, a first-stage exhaust pressure, a first-stage compressionmulti-party process index, a cooling medium inflow temperature, a second-stage air inlet pressure and a preset total compression ratio; the controller determines a first-stage exhaust pressure targetvalue according to the first-stage compression ratio and a second-stage exhaust pressure preset value; the controller performs compression work optimization on the first-stage inverter compressor unitaccording to the first-stage exhaust pressure target value; and / or the controller performs compression work optimization on a second-stage inverter compressor unit according to the second-stage exhaust pressure preset value. According to the control method and device for air compressor compression work optimization and the equipment and the storage medium, the optimal first-stage compression ratio and the optimal second-stage compression ratio can be distributed, and optimal control over the compression work of a two-stage variable-frequency screw air compressor is achieved.
Description
technical field [0001] The present application relates to the field of two-stage frequency conversion screw air compressors, in particular to an air compressor compression work optimization control method, device, equipment and storage medium. Background technique [0002] Most screw air compressors are twin-screw air compressors, which are divided into two series: single-stage compression and two-stage compression. Because the compression of each stage of the two-stage compressor is smaller than that of the single-stage compressor, the internal leakage of the compressed gas is low, and the gas production is generally larger than that of the single-stage compressor. [0003] At present, there is a trend in the domestic market that two-stage compression screw air compressors will gradually replace single-stage compressors. [0004] In the current two-stage compression screw head, the two-stage screw is driven by gears, so the speed ratio of the two-stage screw is fixed; in a...
