This original system can use a renewable energy resource, respectively groundwater, rivers or sea water and can achieve both the heating and cooling requirements of a location. The study represents also a research in the field of energy efficiency and environmental optimization of heat pumps by changing the refrigerant R407C to R290.<br>For testing, an open circuit water-to-water heat pump was used, with capillary evaporators in an original spiral shape able to avoid clogging, by continuous self-washing effect.<br>The simulations showed that the heat pump ensures a reduction of the electricity consumption and Total Equivalent warming Impact by up to 50% compared to an ordinary air conditioning system.</p> ER -
