A solar radiation energy collector must include such a means of stopping solar radiation that no radiation is reemitted. Known art black, heat-binding absorbing surfaces are of this kind. The collecting of solar radiation energy should take place using a liquid jacket covering the entire south-facing pane of the roof, the said liquid jacket being implemented by means of a relatively inexpensive, well-sealed structure that should also be capable of withstanding strains such as that caused by snow. Underneath solar radiation energy collector's intermediate spaces (5) for the heat-collecting liquid, there is a dark-surfaced mineral wool board (1) stopping solar radiation. The intermediate space (5) may be located between two light-admitting membranes (2 and 3) and overlying the membranes (2 and 3) there may be a light-admitting sheet of corrugated fibreglass (4). Between the membranes (2 and 3) or equivalent there may be ridges (6) forming cross-sectionally rectangular intermediate spaces (5) between the membranes (2 and 3). The intermediate spaces (5) may be arranged in tiers; e.g. three tiers with the uppermost tier being a heat-insulating air space and the lowermost tier containing a mineral wool board (1). |
