Water Cooled Condenser; Lphw Coil - Dantherm DanX AF Series User Manual

3. INSTALLATION

3.6.3 Water cooled condenser

As an option the heat pump in a DanX AF unit can be fitted with a water-cooled condenser,
so that any surplus heat, which can not be used for heating up the supply air, can be
transferred to the pool or sanitary water.
NB!
It is important that the material which is used to connect the water cooled condenser is
suitable for chlorine water. It is also important that no more than the specified water volume
(se table below) is pumped through the system, as a to high water velocity can destroy the
water cooled condenser and cooling circuit of the DanX unit.

3.6.4 LPHW coil

Connect 1 and 2 row LPHW coils always in the bottom with the supply and with the outlet in
the top, as these makes it easier to bleed the coil for air. If the coil is larger than 2 rows
connect the coil in that way that the water flow is against the air flow (counter flow) to get the
calculated heat capacity out of the coil.
NB!
When connecting the heat exchanger, counter hold with a suitable tool in order to avoid any
damage to the pipes. Mount the connections in a way that it is possible to access the heat
exchanger for maintenance afterwards.
