Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solar heating, in particular to a solar water heat storage system for heating. BACKGROUND

[0002] The solar heating system is a system that collects solar radiation by using a solar collector and converts it into heat energy, uses liquid as a heat transfer medium, and uses water as a heat storage medium. The heat is sent to the indoor heating through the heat dissipation components. Solar heating generally consists of a solar collector, a heat storage water tank, connecting pipelines, an auxiliary heat source, heat dissipation components, and a control system.

[0003] With the continuous implementation of solar heating systems in society, some drawbacks have gradually appeared in the practice process, and the appearance of these drawbacks directly leads to the fact that traditional solar heating systems cannot meet the high standard use requirements of users. The drawbacks of traditional solar heating systems are listed as follows:

[0004] 1. The traditional solar heating system uses domestic water as a heat storage medium. When the water is heated to the appropriate temperature, the heated hot water is stored and used. However, the traditional solar heating system is prone to scale during the heating process of domestic water, and the appearance of this scale phenomenon directly leads to the phenomenon of blockage of the connecting components such as pipelines of the traditional solar heating system. To deal with such phenomena, professional maintenance personnel in the field need to disassemble the device in sections and clean the deep inside of the device to achieve the purpose of completely cleaning the scale. This maintenance method is time-consuming and labor-intensive, and directly affects the working efficiency of the traditional solar heating system.

[0005] 2. The traditional solar heating system needs to rely on a solar collector to work. However, in cold weather, the solar collector with increased temperature inevitably dissipates heat to the surrounding area through conduction, convection, and radiation. If so, it will directly cause heat loss of the collector, thereby directly reducing the heating efficiency of the traditional solar heating system.

[0006] 3. The traditional solar heating system lacks a complete adjustment system that can adjust the temperature in real time according to the change in the temperature of the water stored after being heated by solar energy. This adjustment system can still efficiently heat the stored water to meet the high standard use requirements of the required heating system environment when the heat loss occurs after the stored water is heated by the solar heating system.

[0007] In view of the above-mentioned drawbacks, there is an urgent need in the field of solar heating for a new solar water heat storage system for heating to solve the above-mentioned problems. SUMMARY

[0008] Therefore, the solar water heat storage system for heating is provided to solve the problems of the traditional solar heating system, such as the scaling blocking the pipeline, the heat loss of the solar collector, and the lack of the temperature control system for the heated water.

[0009] The solar water heat storage system for heating is achieved by the following technical solutions.
