Swimming pool heat pump

per 30 meters could roughly be estimated at 0.6 kW/ hour for every 5 temperature difference

between the pool water and the soil surrounding the pipe, which translates to an operation time
increase time increase of 3-5%.
Swimming pool water chemistry
Special attention should be paid to the chemical balance of the pool water. The pool water value
should always within the following limits:
Item Min Max
pH 7.0 7.4
Free chlorine (mg/l) 0.5 1.2
TAC (mg/l) 80 120
Salt (g/l) 3
Note: Failure to comply with these limits will invalidate the warranty.
Exceeding one or several limits can damage the heat pump. Always install water treatment
equipment past the heat pump’s water outlet, especially if the chemicals are automatically added
to the water.
Attention
1. The water flow can not be lower than the unit standard value (please refer to the nameplate).
2. The insulation of water pipe should be done well to prevent energy loss.
3. A suitable draining valve should be installed in the bottom point of water system.
4. For controlling the time spent to wash and clean system and preventing the dreg or sediment
in the system pipe line to enter into the heat exchanger, a by-pass pipe line should be reserved
between supply water and return water pipe.
5. When circulation water is running initially, close the inlet and outlet valves of the unit, open
the bypass valve; after water pump is running for a while, clean the water filter netting; after
confirming there is no mess in the external circulation system, then open the inlet and outlet
valve of the unit, close the bypass valve, then make the unit operated normally.
For all above demonstrations are only for your reference, the practical project should be carried
out by professional persons according to standard and design requirement.
