Problems solved by technology
[0006] Due to the constant heat storage capacity of the heat storage material of the existing phase change heat storage solar energy, when the radiation is strong in summer, the heat absorption capacity of the water heater is greater than the heat storage capacity, which will cause the temperature of the heat storage material of the water heater to be too high; When it is insufficient, the heat absorption capacity of the water heater is less than the heat storage capacity, and the heat of the water heater is insufficient to meet the bathing requirements

Provided is a solar water heater with a heat balance device. The solar water heater with the heat balance device comprises a phase-change and heat-accumulation solar water heater, a circulation water pump and a heat balance tank, wherein the phase-change and heat-accumulation solar water heater, the circulation water pump and the heat balance tank are connected in series, and a heating device is arranged in the heat balance tank. When solar irradiation is strong in summer, temperature of heat storage materials in the water heater reaches a certain value, the circulation pump is started, heat is transmitted to the heat balance tank from the water heater through circulation of water, temperature of the water heater is prevented from being too high, and heat cannot be wasted. When the solar irradiation is insufficient in winter, the heating device and the circulation pump in the heat balance tank are started, electric energy is transferred into heat energy, and the heat is stored in the heat balance tank and the water heater respectively, and heat in a system is guaranteed to be sufficient to meet bathing requirements of a user. Meanwhile, when temperature of outdoor pipelines of the system is low, the circulation pump is started to convey hot water to the pipelines, and the pipelines can be prevented from being blocked due to freeze.
Description
technical field [0001] The invention relates to a solar water heater with a heat balance device, in particular to a phase change heat storage solar water heater with a heat balance device, and belongs to the field of solar photothermal technology. Background technique [0002] With the rapid development of China's economy and the continuous improvement of people's living standards, the demand for energy is also increasing. The current energy consumption is mainly fossil fuels such as coal, oil and natural gas. Due to the limited oil reserves in our country, nearly 50% of crude oil is currently imported, and coal is still the main source of fuel and power in our country. The environmental problems caused by coal burning have become a problem that must be taken seriously in our sustainable development strategy. Solar energy is a huge energy source that does not pollute the environment. The solar energy that the earth obtains every second is equivalent to the energy emitted by...
