Desalination station of the distillation type comprising: - a hot area defined by a casing and by a hood containing water with dissolved solids up to a first level; - a feeding area of the water with dissolved solids towards said casing; - a cold area consisting of a container in which the condensation of said water vapour coming from said hot area occurs, said condensation involving the formation of water without said dissolved solids up to a second level; - a drawing area of the water which condenses in said cold area; - at least one heat pump transferring heat from a refrigerating plate present in said cold area to a second heat exchanger present in said hot area for giving heat to said water with dissolved solids and causing the evaporation of said water contained in said casing with the formation of water vapour in said hood; - transferring means of said water vapour from the hood of said hot area to the refrigerating plate of said cold area; - a control area comprising a control board for controlling the operation of at least said heat pump; - a power supply generation area comprising at least one photovoltaic solar panel for generating electric power supply for at least said heat pump and said transferring means of the water vapour and making said desalination station autonomous from other external energy sources; and - a heating area, wherein the at least one photovoltaic solar panel is combined with a circulation system of a cooling fluid, said heating area comprising a circulation pump of the cooling fluid supplied by said photovoltaic solar panel and controlled by a control board for circulating said cooling fluid in correspondence of said at least one solar panel, such that heat from said at least one solar panel is transferred to a first heat exchanger which transfers heat to the water with dissolved solids contained in the casing of said hot area; characterised in that the water vapour from the hood of said hot area is transferred to the refrigerating plate of said cold area by means of a damp air circulation pump, which sucks in damp air by means of a suction inlet present in said hood creating thus a depression in said hood and favouring the evaporation of water, and a damp air duct, which conveys said water vapour at high speeds up to said cold area, creating thus an overpressure in said container and favouring the condensation of the vapour; wherein the hot area further comprises a diffuser immersed in said water with dissolved solids at a given level with respect to said first level of the water with dissolved solids, such that dry air present in the container of said cold area is drawn from an air outlet and conveyed through a dry air duct up to said diffuser, the level of said diffuser with respect to said first level of the water with dissolved solids defining a thickness of water, which determines a corresponding depression of stimulation of the evaporation; and wherein said diffuser distributes said conveyed air on a surface which is at least two orders of magnitude greater than the section surface of said damp air duct for obtaining a corresponding transit speed reduction of said conveyed air on the thickness of the water for the evaporation.
