Design Information Vitosol 200-T, SPE Technical Data Installation on Flat Roofs When installing collectors, maintain the minimum clearances towards the roof edge in accordance with DIN 1055. If the roof size necessitates a split array, ensure that sections of the same size are created. The collectors can be secured on any solid substructure or on concrete slabs. When installing collectors on concrete slabs, secure them with additional ballast against slippage, tipping and lifting.
Design Information Vitosol 200-T, SPE Technical Data Installation on Flat Roofs (continued) Determining the collector row clearance z At sunrise and sunset (when the sun is very low), shading cannot be avoided when collectors are arranged behind one another. To keep the reduction in yield within acceptable parameters, observe specific row clearances (dimension z). When the sun is at its highest on the shortest day of the year (21.12), the rows at the back should be free of shading.
Design Information Vitosol 200-T, SPE Technical Data Installation on Flat Roofs Horizontal installation (non-elevated) Yield can be optimized by rotating the vacuum tubes to 45° to the horizontal plane. The collector must be sloped greater than 0°. Ballast and maximum load on the substructure Calculation in accordance with DIN 1055-4, 3/2005 and DIN 1055-5, 7/2005 or applicable local codes. Two support slabs each, both A and B are required for every collector.
Design Information Vitosol 200-T, SPE Technical Data Installation Examples Take venting into account when engineering the collector array. Note: Max. 215 ft2 (20 m2) absorber collector area can be connected in series to form a single array.
Design Information Vitosol 200-T, SPE Technical Data Pressure Drop Relative to water, corresponds to Tyfocor LS at approximately 140° F (60° C). Pressure Drop Note: For multiple collector arrays, use the total flow for the whole array to calculate the pressure drop. Flow Rate 10 5693 556 v1.0 A 1.63 m2 B 3.
Design Information Vitosol 200-T, SPE Technical Data Flow Rate SPE collectors have minimum required flow rates (lowflow mode), and maximum flow rates (high-flow mode). The collectors must operate within this range, and the designer must choose a flow rate based on the specific parameters of the system. High-flow mode High-flow mode results in low temperature spread across the collectors, but may require bigger pump and pipe sizes for large systems.
