Solar energy collecting and storing system

Abstract

A solar energy collecting and storing system includes a solar energy collecting unit and a heat reservoir. By the thermal energy collector, solar light is absorbed and converted into thermal energy for heating a working fluid contained in the thermal energy collector. Multiple input / output control valves and multiple input / output joints are connected with the heat reservoir for controlling the working fluid to flow into or out of the heat reservoir. If the light exposure is insufficient, the input control valve is closed and the heat reservoir is maintained in a thermally isolated state. For utilizing the thermal energy, the output control valve is opened and thus the thermal energy contained in the working fluid is transferred to the thermal energy application device through the thermal energy output piping line.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a solar energy collecting and storing system, and more particularly to a solar energy collecting and storing system for converting solar energy into thermal energy, which is used in a thermal power generator and / or an indoor heating device if necessary.BACKGROUND OF THE INVENTION[0002]Recently, the ecological problems resulted from fossil fuels such as petroleum and coal have been greatly aware all over the world. Consequently, there are growing demands on clean energy. Among various alternative energy sources, solar energy is expected to replace fossil fuel as a new energy source because it provides clean energy without depletion. A conventional solar system has a thermal energy collector for converting solar energy into thermal energy, which is used in a hot-water heater, a thermal power generator and / or an indoor heating device if necessary. In other words, after the solar energy is converted into thermal energy by the ...

AI Technical Summary

Benefits of technology

[0005]It is an object of the present invention to provide a solar energy collecting and storing system for converting solar energy into thermal energy. The thermal energy is stored in a heat reservoir. If necessary, the stored thermal energy could be used in a thermal power generator and / or an indoor heating device at any time. In other words, the influence of light exposure amount is reduced.

Problems solved by technology

The conventional solar systems, however, still have some drawbacks.

In a cloudy day or a rainy day, the solar systems fail to normally provide thermal energy to the thermal power generator and / or an indoor heating device.
