The air delivery coefficient, also known as volumetric efficiency, is the ratio of the actual exhaust volume when converted to inhalation mode to the theoretical exhaust volume. The gas delivery coefficient indicates the degree of utilization of the volume between the rotor teeth of the compressor, and it is an important indicator for assessing the quality of the machine’s design and manufacturing.
The compressor volumetric efficiency is the ratio of the actual volumetric flow rate of the compressor to its theoretical volumetric flow rate. The gas transfer coefficient (λ) can be expressed by the following formula: λ=λVλpλtλl, where λV is the volume coefficient, and λp is the pressure coefficient ； The gas delivery coefficient can, to some extent, be understood as volumetric efficiency

The compressor volumetric efficiency is defined as the ratio of the actual volumetric flow rate of the compressor to its theoretical volumetric flow rate. The gas delivery coefficient (λ) can be expressed by the following formula: λ=λVλpλtλl. Here, λV is the volume coefficient, which is related to the clearance volume; λp is the pressure coefficient, associated with the pressure losses during the suction process; λt is the temperature coefficient, related to the temperature inside the compressor cylinder; λl is the airtightness coefficient, related to the degree of sealing in the compressor. The gas delivery coefficient can, to some extent, be understood as volumetric efficiency.
