Solar energy system capable of intelligently controlling opening degree of valves

Abstract

The invention provides a solar energy system capable of intelligently controlling the opening degree of valves. The system comprises a water heater and a heat reservoir and further comprises the main pipe valve, the main pipe valve is arranged on a main pipeline of the upstream of the water heater and the heat reservoir, the system further comprises a central controller, the central controller is in communication data connection with the heat reservoir valve and the water heater valve, a third temperature sensor is arranged at the position of a hot fluid inlet of the water heater and is used for measuring the temperature of the hot fluid entering the water heater, the third temperature sensor is in data connection with the central controller, and the central controller automatically controls the opening degree of the water heater valve and the heat reservoir valve according to the temperature detected by the third temperature sensor. By virtue of the operation, when the temperature of the hot fluid is high, redundant heat can be stored through the heat reservoir after the production requirement for heated water is met, when the temperature of the hot fluid is low, more hot fluid can enter the water heater to be used for heating water, so that the requirement for the heated water is ensured, and meanwhile energy is saved.

Description

technical field [0001] The present invention is one part of the subject project jointly researched and developed with the university, is an improvement on the previous application, relates to the field of solar energy, and in particular relates to a method and system for utilizing solar energy. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Solar thermal conversion is a solar energy utilization method with high energy conversion efficiency and utilization rate and low cost, which can be widely promoted in the whole society. ...

AI Technical Summary

Problems solved by technology

During the evaporation process of the heat pipe, it will inevitably carry liquid to the steam end. At the same time, because of the exothermic condensation of the condensation end, there will be liquid in the condensation end, and the liquid will inevitably mix with the steam, so that the fluid in the heat pipe is vapor. Liquid mixture, the existence of vapor-liquid mixture causes the gas to mix together, and the heat exchange capacity between the liquid and the liquid decreases, which greatly affects the heat exchange efficiency

[0005] In the solar energy utilization system of the prior art, there is a lack of research on intelligent control, especially the intelligent control when there are multiple solar energy utilization devices at the same time, such as setting heat distribution, etc.
