The Heat Pump is, at present, the most economic device to warm the water of a swimming pool and this explains its increasing popularity for some years. The functioning of the heat pumps, as that of the refrigerator, is based on the capacity of the refrigerant fluids to vaporize and to condense in ambient temperature. The fluid used in the circuit of a hot air pump was for a long time R22 but it is now replaced gradually by gases of replacement such as R407C, harmless for the ozone layer.
The Heat Pump is installed on the filtration circuit of the swimming pool and it is the filter pump of this last one which allows the circulation of the water in heat exchanger of the heat pump . It is in the same heat exchanger that circulates the refrigerant fluid which, having got the calories of the ambient air, will be warmed by the compressor and will restore some heat to the water of the swimming pool. The electrical power supply of a heat pump serves only for insuring the traffic of its refrigerant gas through the various elements composing its circuit, from the captation of the ambient air calories up to the heating of the water of the swimming pool . It is necessary to know that near 0°C the heat pump efficiency is low and that, in these climatic conditions, the heating of a swimming pool outdoors can be insured with difficulty. However, if this outdoors swimming pool, equipped with a heat pump, is, as early as possible, protected with a cover, the season of bathing will be prolonged by several months, even up to a year. The Heat Pump is the ideal complement to your swimming pool.
