Description

Technical field: [0001] The invention relates to a heating system, in particular to a combined heating system of solar energy and condensing gas wall-hung boiler and an intelligent control method. Background technique: [0002] With the rapid development of the national economy, the development of strategic emerging industries, the promotion of industrial structure adjustment, especially the promotion of energy conservation and emission reduction, the development of low-carbon economy, and the acceleration of the construction of key energy conservation and environmental protection projects have become the only way for China's economic development. . In the vast areas of the north, heating energy consumption in winter accounts for more than 20% of the total energy consumption of the society. As a clean and environmentally friendly green energy, solar energy can replace 150 kilograms of standard coal per square meter per year, which is equivalent to saving 417 degrees of elec...

AI Technical Summary

Problems solved by technology

[0003] At present, the solar heating system on the market is composed of roof solar heat collection system, heat storage system, electric heating system, heat tracing system, control system and heat dissipation system, etc. Due to its unreasonable structure, the existing solar heating system has the following disadvantages: 1. Most of the traditional terminal heat dissipation systems use radiators and geothermal coils. It has a good heating effect; and there is no automatic temperature control function and timing function, the water temperature is low and the room cannot be heated, and the water temperature is high and the heat is unbearable

3. When the heat collection temperature of solar energy does not reach the heating temperature during the day, or when it is continuously cloudy and snowy, the heating needs to start the electric heating system inserted in the water storage tank. The power of the electric heating tube is very large, and it needs to consume a lot of electric energy , the operating cost of the electric heating tube accounts for at least 80% of the entire heating cost, so it is not energy-saving

4. The outdoor heating pipeline needs electric heating as a heating system for anti-freezing, which also consumes a lot of electric energy

5. Although the control system can realize automatic control, it cannot optimize parameters according to changes in climate and temperature to make full use of solar heating

Therefore, this solar heating system has not been really applied in the severe cold regions of the north.
