For regions where the atmospheric conditions do not change significantly with the seasons over a long period of time, the collector should be oriented toward the south. When the dip angle is approximately equal to the local latitude, the maximum annual solar radiation energy can be obtained. Selection of heat collecting tube The heat collecting tube adopts a high vacuum double glass tube with high heat collection efficiency, high light transmittance, good resistance to cold and hot shocks, high mechanical strength, resistance to hail below 25mm, and design life of more than 15 years. At the junction of the heat collecting tube and the joint collecting tube, a flanging structure and multiple semi- "O" sealing rings are adopted for reliable sealing. The inner bladder and outer shell of the joint header are made of stainless steel, and the tailstock is made of nylon and has a unique structure, so the pressure bearing capacity is stronger. Stainless steel bellows are used for connection between each group of collectors. The lighting area of ​​a single group of collectors is 6.25m2, a total of 56 groups, and the total lighting area reaches 350m2. Insulation water tank and pipeline design Insulation water tank is the main equipment for heat storage, at the same time it can play a role in stabilizing the water temperature, and must be reasonably matched with the solar heat collection area to facilitate the smooth heating. If the volume of the water tank is too large, the temperature of the water is difficult to rise; if the volume of the water tank is too small, overtemperature is easy to occur in summer, which affects the safety of water supply. In addition, the volume of the water tank is also related to auxiliary heating. The larger the heat storage volume, the less auxiliary heating is required. Generally speaking, the volume of the hot water storage tank required by the solar collector is 40 ～ 100L / m2. When the actual area of ​​the solar collector is less than the calculated value, a low value is generally adopted to obtain a more ideal hot water temperature. The water tank is generally installed on the load-bearing wall of the building, the load-bearing beam or the water tank foundation. The closer the water tank to the heat collecting plate, the better. The circulation pipe should be aluminum-plastic composite pipe (hot water) or galvanized steel pipe. The direction should have a slope of not less than 1%. In order to reduce heat dissipation and winter antifreeze, 50mm thick rock wool pipe is used for pipeline insulation. After bitumen cloth is used for waterproofing, the surface is wrapped with aluminum foil cloth. The installation of pipeline supports is generally not for load-bearing purposes, but is mainly fixed, mainly to prevent the "reverse slope" caused by the bending of the pipeline from affecting the system circulation.
