Figure 8: Design of advanced covering membrane. Notations: (a) Big fragment of cover with controlled clarity (reflectivity, carrying capacity) and heat conductivity; (b) small fragment of cover; (c) cross section of cover (film) having 5 layers; (d) longitudinal cross section of cover; (1) cover; (2) mesh; (3) small mesh; (4) thin electric net; (5) cell of cover; (6) margins and wires; (7) transparent dielectric layer; (8) conducting layer (about 1–3 μ); (9) liquid crystal layer (about 10–100 μ); (10) conducting layer; (11) transparent dielectric layer. Common thickness is 0.1–0.5 mm. Control voltage is 5–10 V.
