How to install the home radiator? Radiator installation process, read to understand!

First, the home heating installation of the three ways:
The first installation method: natural circulation installation method When the radiator is installed, the pipeline must have a certain slope, and there must be a certain height difference between the radiator and the boiler, and usually the distance is 0.5 meters or more. Diameter of the radiator pipe is generally DN-25 and DN--40, and the farthest end should not exceed 15 meters. The advantage of this diameter is that the heating effect can be achieved completely by the natural circulation method; the disadvantage is that the temperature difference between the upper and lower sides is relatively large, the height installation of the radiator cannot be too low, and all of its decoration effects are not beautiful.
The second installation method: increase the heating circulation pump method to increase heating circulation pump method is based on the installation of the natural circulation, will be installed on the water outlet of the water pipe heating circulation pump, so that it achieved a good cycle effect This method can be safely used in areas where power is often cut off.
The third installation method: automatic pump circulation installation method This installation method can completely place the radiator on the ground, so that there is no certain height difference between the radiator and the boiler; of course, can also play a good heating Cycling effect, this installation is convenient and quick, heating effect is remarkable, and beautiful. Of course, its disadvantage is that it completely depends on the circulation pump, and it cannot be used in regions where power is often cut off.
Second, the home radiator installation process 1. The first thing to consider when choosing the radiator is the radiator material, because different heating environments use different types of radiators. For our heating situation, we recommend using steel radiators and copper-aluminum composite radiators.
(1) Central heating homes: suitable for the selection of steel column radiators, which have better heat dissipation and pressure resistance and can withstand higher 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.
2. Heat Dissipation For radiators, 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 △T 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 surface of the radiator, which indicates the heat dissipation W of each radiator.
3, the number of pieces to achieve the effect of heating, in fact, is to make the radiator heat capacity and the house required heat to match. 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.
4, the height of the actual height of the radiator is called the full height in the industry, generally have a label on the product, common sizes are several kinds of 600mm, 1500mm, 1600mm, 1800mm, etc., also need to pay attention to some skills when purchasing, pay attention to Radiator safety and compatibility with home furnishings.
(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 at the middle floor can choose freely. This approach considers the problem of heating pressure at home and prevents 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.
In order to ensure the installation of the heating effect, the overall appearance and the service life of the radiator, there are some details to be noted during the installation of the radiator. For example, radiators can not be added, this will not only affect the cleaning effect of the radiator, but also affect the cooling effect. The most important installation of the radiator is the choice of the location of the radiator installation. It should be installed at a lower position, such as under the window, because according to the principle of air flow, the hot air rises and the cold air falls into convection. It is convenient for the indoor temperature to reach equilibrium, and it will not cause a large loss of heat. In addition, the advantage of installing under the window is that it can heat the cold air that flows in from the window, so as to avoid the uncomfortable feeling of uninvited guests such as cold air entering the house.
