Design Selection and Example

Radiator Selection:

1、According to the principle of matching the heat consumption of the room with the heat dissipation of the radiator, the type selection is carried out.

2、Give consideration to the comfort and beauty of the room to determine the type of radiator in line with it.

3、Calculating Method of Radiator Selection:A= Q q*β1*β2*β3

According to the inlet and outlet water temperature of the radiator, the average water temperature of the radiator can be calculated.:T jp= T in+T out 2

Calculate the temperature difference of heat dissipation according to the indoor design temperature:△T=T jp-T

According to the △T heat sink selection table, the heat dissipation of a single chip can be obtained.q.

Notices for Design and Installation

Radiator installation:

1. Load-bearing wall installation (Fig. 1): the installation height of radiator bottom from the ground h (> 100MM). Fixed bolt positioning dimensions for different types of products are shown in the chart.

2. Installation of non-load-bearing wall (Fig. 2): In this case, it is necessary to punch through the hole of the wall, penetrate through the screw rod, and fix the steel plates on both sides of the screw wall. The length, width and thickness of the steel plates should not be less than 30*30*3 (MM), and the installation dimension of the solid wall should be the same.

3. Installation of internal thermal insulation wall (Fig. 3): In this case, expansion bolts must penetrate the internal thermal insulation layer and penetrate into the wall. The length of penetration into the wall is not less than 50MM, and the installation dimension is the same as that of solid wall.

Method of connecting radiator:

Cautions for Radiator Installation:

1. When installing, make sure that the distance between the bottom of the radiator and the ground is not less than 100MM, and the distance between the top of the radiator and the top of the radiator is not less than 100MM.

2. Installation should ensure that the top of the radiator is straight, with a slightly higher wind end, so as to facilitate the emission of gas in the radiator.

3. Pipelines and radiators should be beautifully arranged, but they must meet the requirements of relevant specifications, but ensure safety and convenient maintenance.

4. The radiator hook should be fixed on the load-bearing wall. The distance between hooks should be based on the distance between the radiator and the corresponding sheets. It is not suitable to concentrate or disperse excessively. When long sheets are encountered, the number of hooks should be increased appropriately, and the height should be determined by the height of the radiator. The hook should be in line with the horizontal and vertical directions on the wall. If the wall is not a load-bearing wall, the metal baffle should be padded before hanging. Distribution of installation spacing of hooks is shown in Fig. 1.

5. The radiator should be packaged to protect the appearance of the radiator.

6. Hydraulic test should be carried out after installation of heating system (fig. 2). Hydraulic test should be carried out on the radiator after installation. The test pressure should be 1.5 times of the working pressure.

7. The water quality of heating system should meet the requirements of GB1576 "Water Quality of Low Pressure Boiler".

Cautions for installation of radiator pipes:

1. Radiator branch pipe should have more than 1% installation gradient in order to facilitate gas emission in the pipeline.

2. Valves should be installed at the inlet and outlet of each group of radiators. In order to facilitate full water maintenance of radiators in non-heating season.

3. When choosing aluminium-plastic composite pipes and other key pipes, it is necessary to confirm that the pipes are heating and hot water pipes, and the pipes should meet the relevant national or industry standards. The pressure of pipe and fittings should be no less than the experimental pressure of pipe network system.

4. When pipelines pass through walls and floors, protective sleeves should be installed.

5. When plastics pipes are installed in plastics, pipe cards should be installed every 300 mm.

6. If the temperature control valve is installed, the temperature control valve should be installed at the intake, and should be installed horizontally. If affected by space, the temperature control valve can be installed vertically upward but not downward. When installing the temperature control valve head, pay attention to the scale up for observation. .5 times.

7. For the hot water heating system under 100 ~C, the water quality should reach: PH value (20 ~C), pure aluminium 6-8.5, steel aluminium 7-12, conductivity ≤250ms/m, CI-1≤100mg/l, and O2≤100mg/l.
