Background technique

With the development of society, energy shortage and environmental pollution have become the bottleneck restricting sustainable development, and the application of renewable energy has been paid more and more attention. As a relatively economical and relatively mature technology, solar water heating has been applied on a large scale. In particular, the popularization and application of household water heaters account for about 90% of solar thermal utilization; solar centralized hot water systems account for about 10%. According to the investigation and research on the current solar water heating technology, the following disadvantages generally exist:

1. In low-rise residences, compact water heaters with top water and sun drying are generally used, which have problems of low thermal efficiency, poor water quality, easy scaling and unstable water pressure, and cannot meet the requirements of hygienic standards and hot water comfort.

2. The split-type solar water heating system requires hot water circulating pumps, heat storage tanks and other facilities, which are expensive, difficult to install, and expensive to operate and maintain. the

3. The traditional centralized solar water heating system needs to occupy the hot water machine room, the overall cost is high, accidents such as pipe bursts and freezing cracks occur frequently during operation, maintenance and management are difficult, and operating costs are high. At the same time, due to the high heat consumption of the water pipe network in the centralized solar water heating system, the comprehensive heat utilization efficiency is low. The power circulation of the circulating pump not only consumes electric energy, but also makes the collector operate under pressure, and the vacuum tube collector is easy to burst; the flat plate collector is used in the northern region, and antifreeze is required in cold regions, and the overall operating cost is relatively high. the

To sum up, there are many problems in the solar domestic hot water system at present, the users are not satisfied, and the developers do everything possible to avoid the installation of the solar hot water system. Improve the current problems in solar energy applications. the
