If all possible water in the air is condensed, � �� will be saturated � �� . The amount of condensed water can then be estimated with the following equation (assuming that the air in point 2 was oversaturated, otherwise �� ). �� ¡ �� This gives a temperature at point 3 of �� ¡ � � � �� ¡ ¡� � with �� ¡ � � � � ��¡� � � � �� ¡ � �� 3.2.4 Heating � � � �� ¡ � �� (3.31) (3.32) Heating can be expressed quite easily compared to the other cases, since the humidity and the mass flow do not change.

An overview and a comparison of the different types can be found in Figure 3.8. The most common type is the plate door. FIG� Space Temp.

The shape of the curve will differ by the type and the position towards the air flow direction. It is also dependent on the air speed. Neglecting other possible - +
