An atomising system on board of the unit creates a very thin water particle mist which by adiabatic evaporating brings the suction air to a homogeneous and almost complete adiabatic saturation. The effect is a reduction of the suction air temperature (respect to the ambient air) and therefore an increased efficiency of the heat exchanger. Generalities:
- Hydrophilic coating of the aluminium fins: weakens the surface tension of water and expedites the formation of a thin film of water on the fins.
- Control box (protection class IP65) factory fitted on the unit and fitted with electronic controls.
- Main inlet and drain solenoid valves.
- Thermostat to command the drainage of the system in the cold season.
- Pressure regulator and gauge, pressure switch.
- Water strainer.
- SOFTWATER device to help preventing scale on the fins.
- Sparge system factory fitted to the unit and made of 25mm UV resistant multilayer tubes with atomising nozzles.
- Adiabatic temperature saturation is a thermodynamic property of humid air. It represents the temperature that can be achieved by air when it reaches the saturation condition through an adiabatic transformation.
- The adiabatic saturation temperature lowers - since evaporating water removes heat - though it is still higher than the dew temperature, as evaporation itself raises the partial pressure of water vapour.
