1. Performance and installation

1.1 Performance and features

√High efficiency
With a COP value up to 5.0 our heat pumps are very efficient when transferring heat from the
air to the swimming pool water. You can save as much as 80% of cost compared to an electrical
heater.
Long life-span
The heat exchanger is made of PVC & Titanium tube, which can withstand and prolong exposure
to swimming pool water.
Easy
control and operation
The unit is very easy to operate: simply switch it on and set the desired pool water temperature.
The system includes a micro-computer controller, allowing all operation parameters to be set.
Operation status can be displayed on the controller with LED display.

1.2 Working principles

Air flow
Compressor
Water flow in
Heat pumps utilize the sun s free heat by collecting and absorbing energy from the outside air.
This energy is then compressed and transferred to the pool water. Your existing water pump circulates
the water through the heater, usually next to the pool equipment, and the water warms up. The heat
pump timer could be set to operate during daylight hours, for example, usually 9am to 5pm.
The unit contains a fan that draws in outside air and directs it over the surface of the EVAPORATOR
(energy collector).The liquid refrigerant within the EVAPORATOR coil absorbs the heat from the
outside air becomes a gas.
The warm gas in the coil passes through the COMPRESSOR concentrating and increasing the heat
to form a very hot gas which then passes to the CONDENSER (water heat exchanger).It is here
that the heat exchange occurs as the hot gas gives off heat to the cool swimming pool water circulating
through the coil.
√The pool water becomes warmer, and the hot gas cooling as it flows through the CONDENSER
coilreturns to its liquid form and, after passing on through the CAPILLARY TUBE the whole
process begins again.
The state of the heat pump technology can efficiently collect heat from the outside air down to the
to 10 range. For tropic and subtropical climates, this means that the pool can be maintained at 26℃
to 32℃
