Solar heating panel for greenhouse - has panes of transparent material with sealed edges for receiving flow of heat conducting fluid

摘要

The solar heating panel is intended to replace the glass panes of a greenhouse and comprises two sheets of transparent plastics material, preferably glass fibre reinforced. These have flexible material around their edges, compressed together by rivets to act as seals. The panels are mounted into the frame of the greenhouse and nozzles are provided at suitable intervals to permit a flow of heat conducting fluid through them. This fluid may be transparent, or coloured to act as a light filter, the heat being used inside the greenhouse.
