Problems solved by technology
The use of solar energy is not very popular at present, and there are still problems of high cost and low conversion efficiency in using solar energy to generate electricity
[0003] Solar energy is unstable: due to the limitations of natural conditions such as day and night, seasons, geographical latitude and altitude, and the influence of random factors such as sunny, cloudy, cloud, and rain, the solar irradiance reaching a certain ground is intermittent , is extremely unstable, which increases the difficulty of large-scale application of solar energy
In order to make solar energy a continuous and stable energy source, and finally become an alternative energy source that can compete with conventional energy sources, the problem of energy storage must be solved well, that is, the solar radiation energy in sunny days should be stored as much as possible for night or rainy days. But energy storage is also one of the weaker links in solar energy utilization

The invention provides a heat energy reserve pool capable of storing heat continuously and relates to the technical field of heat energy reserve. The heat energy reserve pool comprises a trapezoid water storage tank dug in the southern slope, and a heat energy reserve room is arranged in the trapezoid water storage tank and located at the bottom of the trapezoid water storage tank. A longitudinal spirally-rising spiral supporting face is arranged in the heat energy reserve room, energy storage phase-change material boxes are stacked on the spiral supporting face, a water pipe is laid on the spiral supporting face according to the shape, one end of the water pipe is a cold water input end, and the other end of the water pipe is a hot water output end; the trapezoid water storage tank is full of water, the water at the lower portion of the trapezoid water storage tank is composite salt water, and the salinity of water in the trapezoid water storage tank gradually increases from top to bottom. According to the heat energy reserve pool capable of storing heat continuously, solar energy can be fully utilized, heat energy can be reserved in the water storage tank, heat in the water storage tank is preserved through the composite salt water, and the heat loss caused by water convection can be avoided.
Description
technical field [0001] The invention relates to the technical field of thermal energy storage, in particular to a thermal energy storage storehouse for sustainable heat storage. Background technique [0002] Solar energy is both primary energy and renewable energy. It is rich in resources, can be used for free, does not need to be transported, and has no pollution to the environment. It has created a new life form for human beings, and brought society and human beings into an era of saving energy and reducing pollution. The use of solar energy is not very popular at present, and the use of solar energy to generate electricity still has the problems of high cost and low conversion efficiency. [0003] Solar energy is unstable: due to the limitations of natural conditions such as day and night, seasons, geographical latitude and altitude, and the influence of random factors such as sunny, cloudy, cloud, and rain, the solar irradiance reaching a certain ground is intermittent...
