Abstract
An arrangement utilizing solar energy for heating a building having channel spaces in the roof, the outer walls, and the floor, all mutually communicating in series with each other in at least one cross-section of said building and being sealed toward the surrounding atmosphere, a preferably plane solar heat absorbing body being located in one or more of the channel spaces, which channels extend in the circulation path of the air stream along such a body, and a separate channel space including a heat-accumulating magazine.
Claims6
In a building structure provided with solar heating means, comprising a solar heat-exchange chamber and air-circulating channel means extending between opposite ends of said heat-exchange chamber and communicating therewith to form a closed air-circulation loop about at least a portion of said building structure, said solar heat-exchange channel comprising a light-pervious front panel exposed to solar light and solar light-absorbing means positioned to receive solar light by way of said front panel and to convert a substantial portion of said light to heat, the improvement comprising:
- means mounting said light-absorbing means to divide said heat-exhange chamber into a front channel extending between said light-absorbing means and said light-pervious front panel, and a rear by-pass channel extending between said light-absorbing means and a rear wall of said heat-exchange chamber;
- and
- air-flow responsive check valve means associated with said front channel for automatically reducing the air flow through said front channel when the solar heat-producing radiations reaching said solar light absorbing means are strongly reduced or absent, and for permitting said air flow to increase when said radiation increases.
