I. Performance and properties
High performance
Our heat pumps are very ef
fi
cient in transferring heat from air to water in the pool. They can provide savings
of up to 80% in energy compared to an electric heater.
Long life
The heat exchanger is made from a PVC/titanium composite pipe resistant to the long-term effects of pool
water.
Simple operation and maintenance
The device is easy to control: switch it on and set the required temperature of the water in the pool. The
system incorporates a microcomputer control unit which allows all the operational parameters to be speci
fi
ed.
The state of operation can be displayed on the control unit through an LCD display.
II. System design
• Heat pumps make use of free heat from the sun by collecting and absorbing energy from the outside air.
• This device contains a ventilator which draws the outside air in and makes it
fl
ow over the surface of the
EVAPORATOR (energy collector). The liquid coolant in the EVAPORATOR pipeline absorbs the heat
from the outside air and the coolant vaporises.
• The warm gas in the pipeline passes through the COMPRESSOR which gathers the heat and increases the
temperature to generate very hot gas which then passes to the CONDENSER (water heat exchanger). This
is where the heat exchange occurs - the hot gas transfers heat to the colder water from the pool which is
circulating through the coil.
• The pool water is heated and the hot gas is cooled when passing through the CONDENSER pipeline
– it regains its liquid form and, after the passage through the CAPILLARY TUBE, the whole process
recommences.
• The current technology used in the heat pump allows ef
fi
cient use even at an outside air temperature of 7 to 10 ºC.
For tropical and subtropical climates, this means that 26 to 32 ºC may be maintained in the pool under almost any
conditions all year round. In northern countries, the heat pump considerably extends the swimming season.
