Abstract: A method of redistributing heat within a room or for operating a heating system for a dwelling, working or assembly room, together with apparatus therefor, wherein at least one heat pump is employed to extract heat from air of the room on the expansion side (cold side) of the heat pump and to re-emit on the compression side (hot side) of the heat pump the heat to the room in the form of radiation from at least one heat radiation member. The heat exchange may take place directly between the working fluid of the heat pump and the air and the heat radiation member or indirectly employing secondary heat medium circuits containing, for example, water.

Abstract: A roof or wall structure comprises a support framework including battens or the like and a plurality of tile-like solar heat collectors mounted thereon. The solar heat collectors have respective cavities therein within which respective heater coils or the like are disposed. The heater coils have inlets and outlets which are in fluid-flow connection with channels in the battens.

Abstract: A method is provided of constructing rooms provided with a radiant heating system or a cooling system comprising radiant or cooling panels connected to the walls, the ceiling, or the floor of each room and forming a thermal medium cavity, wherein there may circulate a thermal medium which transmits heat to the radiant panels or receives heat from the cooling panels. At least the walls and the ceiling are pre-fabricated components capable of bearing static loads and the interiors of the walls and the ceiling, facing the remainder of the room and the panels, contain respective pairs of adjacent parallel troughs of curved or part-polygonal cross-section. The troughs in the walls are vertical and the ceiling is applied so that they merge streamlined with the troughs in the ceiling. The panels are suspended from supports on the walls and the ceiling with interposition of a resilient packing.
