How to choose radiators for home heating when using radiator heating? This is believed to be a concern for many people. There are so many brands, categories, and materials on the market. I really don't know how to choose a radiator that fits my own home. Here's a simple summary of the next step in the selection of home radiators.
First, the material
The first thing you need to consider when choosing a radiator is the radiator material, because different radiators use different types of radiators.
(1) Central heating households: suitable for the selection of steel column radiators, which have better heat dissipation and pressure resistance, and can withstand greater pressures, because the central heating water pressure is higher than the heating water pressure; Should not use pure aluminum radiators, aluminum die-casting radiators, aluminum alloy radiators, because aluminum is afraid of alkaline water, and centralized heating for the protection of steel boilers, heat exchange stations, pipelines, etc. Generally adjust the PH value to 10-12, for Alkaline.
(2) Wall-hung boiler heating home: suitable for the selection of copper aluminum alloy radiator, because of its small volume, the water quality requirements are not high, while the cooling efficiency is higher than the steel radiator.
(3) single-user heating users: coal stoves, electric stoves, gas stoves, should not use thick tube radiator, coarse tube radiator capacity, slow response, will waste energy.
Second, understand the radiator heating system
The radiator heating system is currently divided into the following categories, which are selected according to the environment of the home heating system.
Third, heat dissipation
For the radiator, the heat dissipation is expressed by the formula Q = KF △ T, where Q represents the heat dissipation, K represents the heat transfer coefficient, F represents the heat dissipation area, and ΔT represents the standard heat transfer temperature.
The heat transfer coefficient refers to the amount of heat emitted by a heat dissipation area per square meter per unit time when the average temperature of the heat medium in the heat sink differs from the indoor temperature by one degree.
The heat dissipation area is the total external surface area where the radiator's heat sink is in contact with the room's air.
The standard heat transfer temperature value is 64.5, according to the national standard operating conditions: Tin (water inlet temperature) = 95 °C, Tout (outflow temperature) = 70 °C, Tromm (room temperature) = 18 °C, temperature difference △ t = 1/2 (Tin+Tout)-Troom=64.5°C.
The heat dissipation of the radiator is proportional to the heat transfer coefficient and the heat dissipation area. When the â–³T is constant, the heat dissipation area F is large, and the heat transfer coefficient K is larger, so the heat dissipation is larger. Generally there will be a label on the radiator surface, indicating the amount of heat radiation W radiator.
Fourth, the number of tablets
To achieve the heating effect, it is actually to make the heat radiation of the radiator match the heat required by the house. Room area * Heat per square meter = room heat required, in order to avoid heating the heat is not enough, usually based on the amount of heat required for the house plus 20-50%, the final value will be the required heat for the house. Next, according to the heat dissipation of each piece of the radiator, the required number of radiators can be directly calculated.
V. Water Quality
(1) Steel Radiator: It is required that the water quality of the heating system should have a PH value greater than 7 and less than 12, because the steel is prone to oxidative corrosion in case of oxygen, and if the oxygen content in the water is high, steel radiators are prone to leakage and corrosion. However, some of the major radiator brands have now strengthened the internal anti-corrosion treatment of the radiators.
(2) Copper Radiator: There is no restriction on the pH of the water quality of the heating system because copper has better oxidation and corrosion resistance. However, copper is rare and precious, and copper radiators are generally very expensive. Common household heating is rarely used.
(3) Aluminum Radiator: The water quality of the system is required to have a PH value of 5-8. Aluminum has good resistance to oxidation and corrosion, but it is resistant to alkaline water corrosion and can easily be corroded in an alkaline environment, resulting in water leakage and explosion. It is suitable for neutral wet alkaline environment with pH=5-8.
(4) Copper-aluminum composite radiator: There is no limit on the PH value of the system water quality. Due to its unique structural characteristics, the internal copper pipe is responsible for water removal, and the corrosion resistance is strong. The external aluminum profile does not contact the circulating water. The duty is sufficient. Play a good advantage of heat dissipation performance. Moreover, copper-aluminum composite radiators are cost-effective and are the type of radiator that most families buy.
For our heating situation, we recommend using steel radiators and copper-aluminum composite radiators.
Sixth, highly selective
The actual height of the radiator is known as the full height in the industry, and it will be generally marked on the product. Common sizes include 600mm, 800mm, 1000mm, and so on. When purchasing, you also need to pay attention to some skills, focusing on the safety of the radiator and The degree of home decoration.
(1) Independent household heating If a wall-hung boiler is used, it is recommended to purchase a radiator below 1.6 meters, otherwise the boiler pressure may not be enough, resulting in poor heat dissipation.
(2) In the case of central heating, users at the top floor may consider installing low radiators. Users at the bottom floor are recommended to use high-heating radiators. Users in the middle floor can choose freely. This approach is to consider the problem of heating pressure at home and prevent them from appearing. Radiator is not hot, burst and other issues.
(3) The height of the radiator placed under the window sill is determined by the height of the sill, and the floor-to-ceiling windows and the large bay windows are suitable for installation of low radiators.

Linear vibrating screens are used to clearly separate all manner of different fractions. Or in technical jargon: Materials are classified accurately.
Thus, in accordance with the standard screening principle, ore, coal, coke sinter, pellets or rocks, for instance, are screened and clearly separated in very large quantities. Linear vibrating screens, which can be specially adapted to the tasks, are critical here to achieving high and consistent quality.
Shenyang SANLAND already provides linear screens in standard format in a variety of designs. For example as single or multiple-decks.
The applications are wide-ranging. Linear vibrating screens are used in the pit, quarry, coal, ore and steel industries.
