6.1.3 Plate heat exchangers for refrigeration circuits
Refrigeration circuits of ETA-POOL-AHUs may contain a condenser for warming the pool water as
an option. The connection of the condenser to the pool water or to the water pipes for general use
must be done according to the blue arrows shown in
Figure 155:

Bottom inlet

Top outlet

Condenser for warming pool water
Application of plastic water tubes are not allowed because refrigerant - and
therefore also plate heat exchanger - may reach temperatures of 110 °C or
higher!
-
Never add the chlorination in front of the water inlet of the plate heat exchanger. The chlorina-
tion should be added as far away from the plate heat exchanger as possible (see
Figure 156
).
-
The water inlet should be close to the surface and the outlet near to the bottom. This improves
the mixing of the heated water and mainly prevents the entrance of chlorine particles or con-
centrated solution into the plate heat exchanger (see
Figure 156
).
Warning:
Unfortunately, in practice, the chlorination is often located in front of
the condenser for warming pool water inlet. This improves the chlorination, but it
could potentially damage the plate heat exchanger.
