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 167:
-
Bottom inlet
-
Top outlet

Condenser for warming pool water
NOTICE!
Application of plastic water tubes are not allowed because refrigerant and in ad-
dition the plate heat exchanger, might reach temperatures of 110 °C or higher!
-
Never add the chlorination chemical in front of the water inlet of the plate heat exchanger. The
chlorination should be added as far away as possible from the plate heat exchanger (see
Fig-
ure 168
).
-
The water inlet should be closer to the surface and the outlet nearer to the bottom. This im-
proves the mixing of the heated water and mainly prevents the entrance of chlorine particles or
concentrated solution into the plate heat exchanger (see
Figure 168
).
NOTICE
!
Warning:
Unfortunately, in practice, the chlorination access is often located in
front of the condenser for warming pool water inlet. This improves the chlorina-
tion, but it could potentially damage the plate heat exchanger.
