Regulation performance of axial flow compressors

The book states that the flow rate of the fan is inversely proportional to the absolute temperature of the atmosphere: lower temperatures result in less intake flow, while higher temperatures lead to more intake flow. As the temperature drops, pressure tends to increase, and as the temperature rises, pressure tends to decrease. However, in practice, when the temperature drops, the outlet flow rate of the main fan increases and the pressure decreases. How can this be explained?
The conditions aren’t clearly specified; if the opening degree of the inlet valve remains unchanged and the air temperature drops, resulting in an increase in density, then the amount of air will increase
