Description

A household heating system with double water tanks of solar water heater and its installation method

technical field

The invention relates to a solar water heater system, in particular to a household heating system of the solar water heater.

Background technique

With the development of society, more and more attention has been paid to energy issues, fossil energy has become increasingly scarce, and energy has become an important factor restricting the development of the world economy. Making full use of renewable energy, especially solar energy, geothermal energy, wind energy, etc., will help reduce the consumption of fossil energy and alleviate the energy crisis. Solar energy has attracted worldwide attention due to its wide range and large reserves. In terms of solar energy utilization, water is often used as the material for storing heat in the system. However, due to the small energy storage density of water, the temperature changes greatly during the heat storage process. , It is easy to cause the heat collection efficiency of the solar collector to decrease during the heat storage process. The phase change material can absorb and release a large amount of latent heat during the phase change process while keeping the temperature constant, and it can store a large amount of heat. Therefore, adding appropriate phase change materials to the hot water storage tank and using the large latent heat of the phase change material can increase the total heat storage energy and energy storage density of the hot water storage tank, thereby improving the performance of the solar water heating system and promoting the utilization of solar energy .

As a household device to improve people's lives, water heaters have been widely used in both urban and rural areas. However, a series of problems will arise during the production, installation and practical process of water heaters.

Because the water heaters are of different sizes and heights, it affects the appearance of the whole building. If the developer installs them uniformly, there are also cobweb-like hot and cold water pipes, which are exposed to the sun and rain. , the pipeline is easy to weather, and the insulation effect is poor. Therefore in order to overcome the drawbacks of existing conventional water heaters, there is an urgent need to invent a kind of water heater that meets energy saving and emission reduction, environmental protection requirements, and is suitable for public residential buildings.

In summary: the existing water heater consumes a lot of manpower and material resources in the installation process, and there are still certain safety hazards. Due to the heating of a single household, a large amount of metal materials will be consumed in the production process, and there will be problems in the use process. Disadvantages of single-family heating.
