Heating system for closed rooms

摘要

In low-temperature radiant heating systems, in particular underfloor heating systems operated with hot water, a problem which occurs is that the cold feeling produced by the radiation of the heat from the radiator in the direction of the cold window or external wall is promoted by a rolling air movement which runs from this front downwards in the direction of the room. According to the invention, it is proposed to arrange, in addition to the radiant heating system, water/air heat exchangers which run parallel to and on the window or external wall of the room and to connect these, on the flow side, between heating-water flow and the radiant heating system. A particularly favourable arrangement results when the outlet ducts are connected by air ducts to air inlet ducts on the opposite side of the room and are all located below the level of the floor. The hot air flow rising out of the water/air heat exchangers prevents both the heat radiation from the body in the window direction and the production of a rolling cold-air movement. On cold days, excessively high temperatures of the radiant heating system alone leading to losses of comfort are thus likewise avoided.
