Choice and installation of the heating system are important development of a residential home or apartment. The required number of radiators depends on the power equipment and floor space. Today, the most popular are aluminum radiators. Technical characteristics and advantages and disadvantages of these heating appliances will be discussed in this article.aluminum radiators specifications

Description

The Main features of this heating equipment are the sections that are filled with water. Water has a large heat capacity that allows it for a long time to hold thermal energy, regularly passing it into the surrounding space.

Varieties

Aluminium radiators (technical specifications discussed below) the type of production distinguish two kinds:

  1. Extrusion.
  2. Sheet.

The Last type consists of separate sections, their number can be reduced or increased if necessary at any time. Extrusion heater has a specific combined number of partitions, their number varies from 6 to 12. The consumer chooses, focusing on the technical features of the house or apartment, what type of product suits them best.aluminum radiators specifications

Heat transfer

Piping hot water is supplied to the lower part of the section, then, due to the convection that is moving up, thereby heating up the surrounding air by the aluminum body. The coolant goes through all the sections, and then through the return pipeline continues its path through the heating system.

Aluminum radiators: technical characteristics

The Section of the heater is made by extrusion of aluminium with the addition of a small amount of silicon. Each section provides upper and lower manifold that connect the vertical channels and ribs of the metal, increasing the heat transfer through extend surface area. Sections are joined together by using elements with a thread, sealed by gaskets from paronite.aluminum radiators features

The Coolant filler sections, heated, simultaneously accumulates and transfers the thermal energy to the room. Due to the good thermal conductivity of aluminium, this unit has a large inertia and efficiency, in contrast to the bimetal and cast iron equivalents.

The more sections, the higher heat output of aluminum radiators. However, one should not get carried away, as too many sections will lead to the fact that some of them will be unused ballast. In this regard, the number of sections should be based on the physical characteristics of the building.

There are Also reinforced aluminum radiators. Technical characteristics these devices allow you to set an arbitrary number of sections, as they are Autonomous in control fluid pressure.

The Section of the heater has standard dimensions:

  • Height – 350-1000 mm.
  • Depth – 110-140 mm.
  • Wall Thickness-2-3 mm.
  • Heating Area-0,4-0,6 m2.
  • Volume aluminum radiator-0,35-0,5 l

The Heat output of the heating device at 50-60% is radiation, convection – 40-50%.

Advantages

  • Low thermal inertia.
  • Light weight.
  • High heat.
  • These heaters are practical, and most importantly - resistant to the chemical action of the coolant.
  • Quite affordable price, which is especially advantageous for high quality of these instruments.
  • Light weight design makes it easy to mount the aluminum radiators. Technical characteristics of this equipment are at a high level.
  • Maintenance – to clean and wash.
  • Appliances are covered with a special heat resistant coating that does not peel.
  • The Design designed in such a way that with a relatively small surface is involved, the maximum volume of air.
  • If desired, aluminum radiator (performance in this case will be much better) you can set the thermal head, which will allow you to adjust the temperature in the room.
  • The Room warms up very quickly, which is very important in winter.

Disadvantages

Besides the obvious advantages, aluminum radiators, technical characteristics of which were discussed above, also have certain disadvantages. One of them is the low resistance of the walls to pressure surges in the heating system. To select the model of radiator must be approached carefully. If, for example, they are made for conditions in Italy, the Russian realities, their strength will be insufficient. Since here the pressure is “jump” more and more. And sometimes it is several times greater than the standard value.capacity aluminum radiator

Another disadvantage is the high sensitivity to impurities contained in the hot water. The quality of the coolant that enters our heating system leaves much to be desired. In the water you can detect physical contaminants in the form of rust, sand, small stones. Contactthe inner walls of all this is the cause of corrosion. Rapid oxidation can result in increased acidity of the coolant. This should be taken into account in a timely manner to change the old device to the new aluminum radiators (specifications listed above).

Reasons of failure

It is Known that in district heating plants water is an alkaline preparation, and in contact with aluminum radiators alkaline environment there is an active evolution of free hydrogen. In the absence of automated equipment for removal of hydrogen gas accumulating inside the aluminum radiator, causing their destruction.heat transfer aluminum radiators

Chemical recovery of hydrogen from the coolant occurs in all heating systems, without exception. However, the radiators that are installed in the system without problems cope with the diversion of off-gas. The aluminium alloy used to produce the heating devices in such a reaction plays a catalytic role, as a result, the amount of hydrogen and the reaction rate is increased many times.

Thus, even a minor disruption in operation of the heating system (not open or clogged vent) can cause the explosion of the radiator, like die-cast, and extrusion. In this regard, in some situations the use of aluminum heating devices is impractical.

Calculate the number of sections

If you opted to purchase this aluminum radiator, it may be able to calculate the number of sections you will require for heating of a room. This absolutely does not require any special math skills.the volume of the aluminum radiator

To calculate need to know the power aluminum radiator (P), which is usually specified in the technical passport, and also need to calculate the area of the heated area (S). The calculation is performed according to the following formula:

S × 100 / P = N, where N-is the number of partitions.

For example, the area of the room – 36 m2, aluminum radiator P standard rate is 190 watts. Thus:

N = 36 × 100 / 190 = 18,95.

Thus, for the heating of our premises will require 19 sections.
