What are the heating methods? What is the material classification of radiator?

Now that living conditions are getting better and better, everyone wants to be warm at home in winter, so it is particularly confusing to choose a suitable heating method. Everyone has his own opinion on the way of heating. Now the Golden Flagship Flag Brother will compare several commonly used heating methods for everyone. Let's take a look at it with the golden flagship flag brother.

What are the heating methods? Radiator materials are classified here.

What is heating?

Narrow sense heating

Refers to central heating facilities. It transports the steam or hot water generated by the boiler to the radiator (radiator) in the room or car body through the pipeline (heating pipe), radiates heat, raises the room temperature, and then flows back to the boiler for reheating cycle.

Generalized heating

Modern equipment that uses other principles to heat is usually called heating equipment. For example:

(1) air conditioning blowing hot air (relative to cold air) can be called heating.

(2) Heating equipment on trains, subways, buses, airplanes and other vehicles, usually air conditioners or heaters. Household heating equipment with radiator appearance, such as electric heater (a kind of electric heater). The following heating equipment is usually called heater: other household heating equipment (such as fan type, heater type, etc.) unlike radiator. ) and are generally called electric heaters and natural gas heaters according to the energy used. The following heating facilities are generally not called heating equipment, such as open-air heating facilities using naked flames, such as fireplaces, coal stoves, charcoal basins, etc.

(3) Kang, which is common in rural areas in Northeast China. Electric blanket, warm water bag and other local heating items. Floor heating and other integral heating equipment.

Radiator classification

1, cast iron radiator:

It is an outdated product. However, due to its low cost and good corrosion resistance, especially the inertia of market demand, it will still occupy a considerable share in the low-end retail market and engineering market in the next few years.

2, steel column radiator:

Its advantages are outstanding appearance and good cost performance. It makes the steel radiator rank first in the sales volume and market influence of new household radiators with overwhelming advantages. In terms of production, steel radiator is easy to obtain, reusable, good in production premise and pollution-free, which has become a national key promotion plan.

However, due to its corrosion resistance and heat dissipation performance, it is not suitable for use in the case of poor water quality.

3. Steel plate radiator:

The aesthetics and corrosion resistance are not as good as those of steel column radiator, but the price is slightly higher than that of steel-aluminum composite radiator. Mainly in the southern market, its market share has an overwhelming advantage.

4, steel fin radiator:

Because of its poor appearance, it cannot be recognized as the mainstream retail market. Compared with steel insert welding radiator, its price has no advantage, and transportation and installation are a bit troublesome. But its price and corrosion resistance are relatively competitive. Mainly in the low-end engineering market, it still occupies a large market share.

5, steel plug welding radiator:

Low comprehensive performance, poor appearance and exposed welding make it difficult to enter the mainstream market; Insufficient durability and compression resistance. It is also difficult to make a big difference in the engineering market. But in the low-end retail market, its price advantage is very obvious, and its appearance and radiator performance are slightly better than ordinary cast iron radiators. Mainly in the low-end retail market, especially in rural markets and towns, while occupying the cast iron radiator market, its market share is still expanding.

6, pure copper radiator:

High cost, low cost performance, difficult transportation and extremely low market share. Advantages: Super corrosion resistance. Disadvantages: high price.

7. Copper-aluminum composite radiator;

Beautiful appearance, corrosion resistance, excellent heat dissipation, mainly used in the northern market, high-end and mid-end markets, areas with poor water quality and markets with gas-fired wall-hung boilers as heat sources. The development of copper-aluminum composite radiator is largely restricted by price factors.

Copper-aluminum composite radiator "thin, high and flat" radiator saves space, but because the higher radiator needs greater water pressure, it is difficult for the boiler with household heating to meet the requirements. Therefore, families with household heating should not choose this type of radiator.

8. Steel-aluminum composite radiator;

Steel-aluminum composite radiator is a kind of synthetic radiator product refined by special welding process, and all indexes reach the ministerial standard. The surface of the composite radiator adopts a new process of electrostatic plastic spraying, which has strong adhesion and long service life. Composite radiator products have the characteristics of fast heat transfer, high pressure resistance, beautiful decoration, warm water and heating, and are widely used in luxury buildings such as houses, hotels, hospitals and offices.

9. Cast aluminum radiator:

The corrosion resistance is too weak, which is not suitable for the retail market and engineering market of central heating in the north. Mainly manifested in the southern heating system with domestic heating stoves as the main heat source. Because the water quality is very good and controllable, the weakness of cast aluminum radiator can be ignored. Belongs to the southern products of China.

10, electric heater:

Also known as Youting, it is a product that converts electric energy into heat energy. With the reform of heating system and the improvement of people's living standards in China, new heating methods are constantly emerging, among which electric heating is increasingly becoming an indispensable heating method. Household electric heating methods are mainly divided into heating cable floor radiation heating, electric heating film heating and electric heating.

1 1. Vacuum superconducting radiator;

The vacuum superconducting heat pipe radiator is based on a brand-new superconducting medium phase change heat transfer principle, which is mainly composed of a radiator high-vacuum main body, a special antirust heat medium composite pipe and a fast heating, antifreeze and high-efficiency heat transfer composite medium (superconducting liquid). Vacuum heating is an internationally recognized environmental protection and energy-saving heating technology. In view of the disadvantages of traditional water heating, such as high energy consumption, slow heat transfer, low thermal efficiency, much waste water, difficult maintenance and short service life, a new type of heating with water saving, energy saving, anti-freezing, corrosion resistance, simple installation and maintenance-free is realized by using the new working principle of superconducting liquid circulating heat transfer in vacuum closed pipes.

12, die-cast aluminum radiator:

In China, die-casting aluminum radiator is also called European aluminum radiator. The main feature is that the head of each column has a die-casting air deflector, and the columns are connected into a whole through internal connection. This kind of radiator has been manufactured and used in Europe for more than 60 years and is widely used in Europe. Mature technology and technology ensure the manufacturing quality of radiator, and its oxygen corrosion resistance makes it have a good service life, so its reliability is very high.
