Abstract (en)
A door opening and closing system (1) having a door (2) and a frame (3), such that one of the edge (4) of the door (2) is in mechanical coupling to one of the edge (5) of the frame (3) for closing or opening of the door (2), the door opening and closing system (1) comprising an arrangement of a first part (6) and a second part (7), the first part (6) is having a cavity (8), and the second part (7) is having a complimentary structure (9) with respect to the cavity (8), such that the complimentary structure (9)to is adapted to makes a fitting into the cavity (8) of the first part (6) when the second part (7) is mechanically coupled to the first part (6) to close the door (2), and the complimentary structure (9) is adapted to release from the fitting to open the door (2), wherein one of the parts (6, 7) is placed on the edge (4) of the door (2) and other part (6, 7) is on the edge (5) of the frame (3) which are in the mechanical coupling for closing or opening of the door (2). At least one of the first part (6) or the second part (7) is having a flexible reservoir (10), and adapted to house water either in solid state or liquid state, the system (1) further comprising a heating and cooling mechanism (11) adapted to be in heat exchange coupling with the water inside the flexible reservoir (10) and adapted to change water into solid state to liquid state, or liquid state to solid state, wherein when the door (2) is to be opened, the heating and cooling mechanism (11) heats the water to change from solid state to liquid state, and when the door (2) is to be closed, the heating and cooling mechanism (11) converts water from liquid state to solid state.
