Description

Technical field [0001] The invention belongs to the field of solar equipment control, and specifically relates to a solar energy non-pressure-bearing anti-temperature saturation control system. Background technique [0002] With the development of the times and the improvement of people's living standards, the increase of high-rise buildings has led to the promotion of the integration of wall-mounted solar energy and large-scale hot water projects. In the national energy conservation and environmental protection advocacy and the actual use effect analysis, split wall-mounted solar energy is the first choice for domestic hot water products. An important indicator for measuring hot water products is the effluent temperature. Products whose temperature does not meet the standard cannot be accepted by consumers. At present, the split wall-mounted solar energy restricts the increase of water temperature during the secondary heating process, and will inevitably lead to the extension o...

Problems solved by technology

At present, when the split wall-mounted solar energy is performing secondary heating, the increase in water temperature is limited, and the heating time of the entire heating will inevitably be prolonged during the process of heating the heat transfer medium, and the optimal heating and lighting time will be missed, resulting in a decrease in heating efficiency.
