ABSTRACT:
A window construction to reduce temperature rises in building interiors caused by direct sunlight entering through the windows. The window comprises two parallel, spaced apart window panes with a space between them filled with a suitable heat exchange fluid such as water. A heat exchanger coupled to a refrigeration system cools the water while the water withdraws heat energy, i.e. infrared radiation from the sunlight. The refrigeration system is activated in response to direct sunlight entering through the window by either employing suitable light/heat sensors or by installing on the exterior building wall adjacent the window a heat absorbing plate which is exposed to the sunlight and which supplies the energy to drive an absorption refrigeration system coupled to the heat exchanger.
