Heat exchanger
The energy content of the sample gas and, as a result, the required cooling capacity of the cooling system is determined by 3
parameters: gas temperature
, dew point
(moisture content) and flow v.
The outlet dew point raises with increasing energy content (heat) of the gas. The required cooling capacity is determined by the
mximum acceptable level of the outlet dew point.
The following table shows cooler performance assuming the following conditions:
=40°C and
=70°C. Indicated is the v
in
Nl/h cooled air (i.e. after the moisture has condensed). With other dew points and gas inlet temperatures the values may differ.
