Description

technical field [0001] The invention relates to hot water heating technology, in particular to a novel all-weather flat solar water heater and a hot water heating method thereof. Background technique [0002] Solar water heater is a device that uses solar energy as energy to heat hot water, that is, a device that uses the energy of the sun to heat water from low temperature to high temperature. It is a thermal product. As a green energy source, the sun has been widely used in construction and other fields Applications. [0003] With the development of solar thermal utilization to this day, great progress has been made both in terms of heat collection efficiency of heat collectors (also known as heat sinks) and in terms of cost performance. Solar water heaters have a very broad market in China, and with the continuous aggravation of the energy crisis, the use of solar energy has been paid more and more attention by the country. Each square meter of flat-panel solar collecto...

AI Technical Summary

Problems solved by technology

[0004] However, the current flat panel (vacuum tube) solar water heater has the following disadvantages: 1. The hot water produced by solar energy cannot be fully utilized, because its working principle is to control the water pump to start through the temperature difference, so that the water circulates through the heat collector to obtain hot water. After the hot water flows to the water tank, it pushes the cold water in the water tank and flows back to the heat collector. When the water temperature on both sides is balanced, the water pump stops working, which causes a part of the water to remain in the heat collector, causing unnecessary waste of heat energy; 2 1. The existing flat plate (vacuum tube) collector is too bulky, requiring high technology and high material cost for installation; 3. Limited by sunlight, the production of hot water is restricted by the weather

4. The pipeline connection between the flat solar water heater and the heat preservation water tank is complicated and inconvenient to install
