Radiator performance indicators and purchase guide

- Oct 25, 2018-

Radiators are an extremely important part of hot water and steam heating systems. The hot water is cooled in the radiator to supply heat to the room to achieve the purpose of heating. Because the metal consumption and cost of the heating system account for a considerable proportion, for the user, the correct selection will involve the economic indicators and operational effects of the system.

 

Simply put, the performance of the radiator mainly includes four requirements. The first refers to thermal performance. In comparison, the higher the heat transfer coefficient, the better the thermal performance of products of the same material. In practical applications, the thermal performance of the outer wall can be further enhanced by increasing the heat dissipation area of the outer wall, increasing the flow velocity of the surrounding air, or strengthening the radiation intensity of the outer surface, or reducing the contact thermal resistance between the various parts.

 

The second performance indicator refers to its economy, that is, the lower the cost per unit heat dissipation (yuan/W) in the process of using the heat sink, the lower the installation cost and the longer the service life. The better its economy. For equipment of the same material, the higher the metal heat strength, the better its economy.

 

The third performance indicator value is the ability to install and use. Simply speaking, the radiator should have certain mechanical strength and pressure bearing capacity, and should be easy to install and combine into the required heat dissipation area; the size should be small, occupying less room area and space; the installation and use process is not easy to break; the manufacturing process Simple and suitable for mass production.

 

The fourth performance indicator refers to hygiene and aesthetic requirements. Under normal circumstances, the outer surface of the radiator should be kept smooth, easy to remove dust; the appearance should be beautiful, and coordinate with the room decoration.

 

Note that when selecting a radiator, you should keep in mind the requirements of these four aspects: 1. Good thermal performance; 2. Pressure bearing capacity meets requirements; 3. Shape should be coordinated with interior decoration, and its size should be adapted to the building size and Requirements; 4, easy to remove ash.
