Paned windows and doors in which there is a plurality of peltier cells

A paned window or door structure including a system for environmental climate control, said paned window or door structure including a frame (2) having a fixed frame portion (2′) and a mobile frame portion (2″) wherein said mobile frame portion (2″) defines a recessed channel having an upper limit and adapted to receive therein a perimetric edge of a double glazing unit (3) which defines between the glass panes a gap (3′), said environmental climate control system comprising:

• in combination, a plurality of Peltier cells (11) arranged along the perimetric edge of said double glazing unit (3) and disposed within the gap (3′) between the glass panes of said double glazing unit (3), a first heat sink element (12) disposed in contact with a lower surface of said Peltier cells (11) for thermal dissipation towards an exterior formed from a material of high heat conductivity and having a portion (12′) arranged at an outer surface of said mobile frame portion (2″), a second heat sink element (13) disposed in contact with an upper surface of said Peltier cells (11) for thermal dissipation towards the gap (3′) between the glass panes of said double glazing unit (3) formed from a material of high heat conductivity, said combination of Peltier cells (11), first heat sink element (12), and second heat sink element (13) being disposed at the perimetric edge of said double glazing unit (3) so as to not project above the recessed channel upper limit of said mobile frame portion (2″);
• and
• an electric circuit (4) for supplying electric power to said Peltier cells (11) including first contacts (20′) arranged on said fixed frame portion (2′) and complimentary second contacts (20″) arranged on said mobile frame portion (2″), and an inverter (9) adapted to invert the electric power supplied to said Peltier cells (11) so as to reverse a heating/cooling mode between the upper and lower surfaces of said Peltier cells.
