CIAT Group, based in France and one of the European leaders in centralized air conditioning and air treatment, recently announced its new AQUACIAT GRAND INVERTER heat pump, which has the special feature of being able to adapt the quantities of energy supplied to suit demand exactly, thanks to the use of a new, variable-power compressor.

Firstly, the compressor does not go through a stop-start cycle; it runs constantly, but at controlled variable speeds. This point is very important, as most of the electric power consumed is used during the start phase. AQUACIAT GRAND INVERTER has a progressive electronic starting system known as a “Soft Starter”, which limits the inrush current. Contrary to a traditional machine, the starting current is lower than the nominal current under full load. Secondly, AQUACIAT GRAND INVERTER constantly optimizes energy efficiency, whereas with a conventional unit, for over 95% of the operating time, the installation’s requirements are in fact lower than the nominal capacity. Lastly, AQUACIAT GRAND INVERTER is also fitted as standard with an electronic pressure reducer that enables the refrigerating system to adjust continuously to suit the compressor capacity. The amplitude of the oscillations between low pressure, high pressure and water temperature regulation is thus reduced by two-thirds.

Furthermore, because it operates with water (the most efficient heat transfer fluid), the Inverter is an ecological alternative as compared with direct expansion systems using refrigerants. Thanks to its characteristics, it complies easily with overall environmental reflections such as HEQ. Moreover, AQUACIAT GRAND INVERTER is especially compact. At equivalent power rating levels, it takes up 35% less floor space. Also, the fan is also of the inverter type, and it supplies only the airflow required. AQUACIAT GRAND INVERTER is also set apart by its low maintenance costs, reveals the company’s press release.
