4.4. Draining out condensate
The outlet condensate connections, led outside the AHU's casing are assembled in the drain plates of glycol,
cross-flow and rotary exchangers (the diameter of drain pan connection pipe is 32mm).
Siphons, which are designed to drain out condensed water from the exchangers at different pressure of the
section and environment, should be connected to the drain connections.
Drain siphons or siphon parts for SVS AHUs are not supplied as a standard delivery.
Siphon’s usable „H" height depends on the pressure difference between the AHU section, where the
condensate is drained during the operation and under the ambient pressure. „H" dimension is provided in
mm and must be higher than the pressure difference expressed in mmH

Fig.11. Ball siphon
It is allowable to join together siphons of various units with one drain interceptor provided that the interceptor is
equipped with air-escape. Before starting the AHU, fill the siphon with water.
It is also possible to use a special type of mechanical pump to force the removal of condensate.

- Connection of coolers should be done in such a way so as not to allow for stresses exchanger s connections which may result in mechanical damages or leakages the pipeline weight and thermal stresses cannot be passed onto the exchanger s connections depending on local conditions please use the compensation at the inlet and outlet of the pipeline system in order to level the pipeline s linear expansion during assembly of the supply system to the cooler equipped with the screwed connections counter the exchanger s connection with additional wrench fig 10
- Examples of connecting inlet and outlet pipelines for various ahu versions shown in the picture 10
- Fig securing the screwed connections of the exchanger 10
- Inlet and outlet exchanger s connections should be connected so that the exchanger operates in a counter current way streamwise operation results in the lower average discrepancy of temperatures which influences the exchanger s performance 10
- Table 2 diameters of coolers connection pipes 10
- The supply system should be planned in such a way so that it does not collide with the other ahu sections the way of connecting the exchangers with the supply system should allow for an easy pipeline disassembly in order 10
