Pressure dew poin and Normal pressure dew point
The correspondence between "pressure dew point" and "normal pressure dew point" is related to the "compression ratio" and is generally represented by a graph. In the case of the same "pressure dew point", the larger the "compression" ratio, the lower the corresponding atmospheric pressure dew point. For example, when the compressed air pressure dew point of 0.7 MPa is 2, it corresponds to a normal pressure dew point of -23 °C. When the pressure is increased to 1.0 MPa, the corresponding atmospheric dew point is reduced to -28 ° C when the same pressure dew point is 2 ° C.
