Abstract:
1. A heat-absorbing window comprising: first and second transparent panes separated from one another to provide a first passageway between the first and second transparent panes for flow of a working fluid through the passageway; a frame in which peripheries of each of the first and second transparent panes are secured; a heat exchanger secured in an upper part of the frame, the heat exchanger including a second passageway for flow of the working fluid and a third passageway for flow of a service fluid; and conduit means coupling the first passageway to the second passageway to make a working fluid flow circuit in the frame through which heat energy absorbed by the working fluid in the first passageway is supplied to the heat exchanger and through which the working fluid exiting the second passageway of the heat exchanger is returned to a lower part of the first passageway, wherein the service fluid flows through the third passageway in a direction opposite flow of the working fluid through the second passageway.
