Description

technical field [0001] The invention relates to the technical field of heating, in particular to a floor radiation heating system based on energy substitution technology, a working method thereof, and a heat calculation method. Background technique [0002] As a clean renewable energy, solar energy has attracted more and more attention. Many developed countries regard the development of photovoltaic photothermal technology as an important way for sustainable development. In my country, photovoltaic photothermal technology as an energy alternative technology has become an important part of the new energy development plan, and its commercial development and utilization is an important development direction. [0003] Compared with traditional heating methods, floor radiant heating has the advantages of comfort, health, long service life and energy saving. The heat source of traditional floor radiant heating generally comes from urban central heating hot water, and the existing...

AI Technical Summary

Problems solved by technology

The heat source of traditional floor radiant heating generally comes from urban central heating hot water, and the existing central heating system is not completely green and environmentally friendly, which is also one of the main reasons for the severe smog in the Beijing-Tianjin-Hebei region; secondly, central heating The temperature of the water is high, which not only affects the living comfort but also wastes heat energy, and the service life of the water pipes is also greatly shortened; in terms of maintenance costs, water floor heating is prone to water leakage during use, which is very troublesome to deal with. After long-term operation, the water pipes There will be a lot of dirt on the inner wall, and the later maintenance cost is relatively high

[0004] Using solar energy as a low-temperature heat source for floor radiant heating systems is an effective way to save energy and reduce emissions. However, due to the instability of solar energy itself, it is easily affected by various factors such as seasons, locations, and climates. The existing photothermal floor radiant heating systems need Solve the problem of insufficient lighting with other methods

In the prior art, there is a system using AC heating cables for heating, but it usually uses 220V mains power supply, which increases the cost of use

In addition, because the electric floor heating technology is still in the development stage, the heating effect of the electric floor heating varies, and there are situations such as large power consumption, insufficient temperature, and difficult temperature control.
