Multifunctional automatic switchable heat-insulating glass and air-conditioning method

A method of switching a multifunctional automatic solar switchable and heat-insulating glass comprising:

• setting switching temperature of a switchable film approximately at a target heating temperature to be controlled in an interior space in contact with said glass;
• the glass operably responding to an actual temperature of said interior space lower than said switching temperature to transmit solar heat from outside;
• and
• the glass operably responding to an actual temperature of said interior space higher than said switching temperature to transmit visible light and reflect heater-heat toward said interior space.

A method of air-conditioning an interior space using a multifunctional automatic solar switchable and heat-insulating glass comprising:

• setting a switching temperature of a switchable film approximately at a target air-conditioning temperature to be controlled in said interior space in contact with said glass;
• the glass is operably responding during heating to an actual temperature of said interior space lower than said switching temperature to transmit solar heat from outside;
• the glass operably responding during heating to an actual heating temperature of said interior space higher than said switching temperature to transmit visible light therethrough and block the release of heater-heat to outside;
• the glass opearably responding during cooling, to an actual temperature of said interior space higher than said switching temperature to block solar heat from outside.

An air-conditioning system comprising:

• a glass substrate;
• a vanadium dioxide-based switchable film;
• a visible-light anti-reflection film;
• and
• an air-conditioning apparatus operable to automatically control a temperature of an interior space in contact with said glass at a given value,
• wherein said vanadium dioxide-based switchable film and said visible-light anti-reflection film are coated on to the glass substrate,
• wherein said vanadium dioxide-based switchable film has a switching temperature set approximately at a target air-conditioning temperature to be controlled in an interior space in contact with said glass, thereby providing a solar switching and heat-insulating functions to said glass,
• and wherein
• said switching temperature of said switchable film is set approximately at said given air-conditioning temperature to be controlled in said interior space in contact with said glass.
