Centrifugal fan to split the air conditioning as the object of analysis, centrifugal fan indoor machine main heat exchangers and fans, the fan is to speed up the heat exchange, usually from the vertical inhalation of air, from below the spray. As the inhaled air is absorbed by the converter when some heat, so the release of air is air-conditioned. The energy absorbed by the exchanger is transferred to the outside by the force of the air, and the outdoor unit compresses the fluorine force and releases the heat and discharges it into the air with the exhaust fan. The main use of gas pressure when the heat, the principle of endothermic when the endothermic. The use of fluoride pressure boost pressure cycle of the indoor heat to the outdoor.

Centrifugal fans are powered by the addition of kinetic energy, gas pressure and the release of gas equipment, it is a driven fluid machinery. Centrifugal fans are widely used in the ventilation, dust and cooling of manufacturing plants, mines, tunnels, cooling towers, automobiles, ships and buildings; ventilation and winds for furnace and industrial furnaces; air conditioning and household appliances The cooling and ventilation of the grain; the drying and feeding of the grain; the source of the wind tunnel and the inflatable and propulsion of the hovercraft.
