Abstract

The invention is related to a climate control system with one dimmable device capable of variably reducing the transmission of radiation through a window, and a climate control unit coupled to and adapted to control the dimmable device. The dimmable device includes at least one inherent conductive polymer and at least one ionic liquid. The dimmable device is controlled to change colours and/or dimming levels by applying a voltage pulse of a first electrical polarisation for darkening and a second reverse polarized voltage pulse for bleaching.

Claims

1. Climate control system comprising at least one dimmable device capable of variably reducing the transmission of radiation through a window, and a climate control unit coupled to and adapted to control the dimmable device, characterized in that the dimmable device includes at least one inherent conductive polymer and at least one ionic liquid electrolyte, the dimmable device is controlled to change colours and/or dimming levels by applying a voltage pulse of a first electrical polarisation for darkening and a second reverse polarized voltage pulse for bleaching.

3. Climate control system according claim 1 wherein the climate control unit is arranged to set the dimming device in a non-transparent mode, in response to an incoming daylight level sensor, and in that the climate control unit is arranged to set the dimmable device in a transparent mode, in response to the at least the same incoming daylight level sensor.

4. Climate control system according to claim 1, characterized in that the climate control system further comprises a cooling/heating system, which is controlled by the climate control unit.

5. Climate control system according to any of the claim 1, characterized in that the climate control system further comprises an illumination system, which is controlled by the climate control unit.

6. Climate control system according to claim 1 wherein the power supply is at least one photovoltaic element, installed on the electro chromic layer.

7. Climate control system according to claim 6 wherein the photovoltaic element covers at least a part of the window.

8. Climate control system according to claim 7 wherein the photovoltaic element forms a frame on the window.

9. Climate control system according to claim 7 wherein the photovoltaic element forms a sun shield in form of a band on top of the window.

10. Climate control system according to claim 6 wherein the photovoltaic element is a solar cell transparent in visible region of light.

2. Climate control system wherein the duration of voltage pulses is in the range of 1 ms to 1000 ms.
