What preparations should be done before installing the air radiator?

2021-09-05Common Problem339

Air radiators are generally suitable for installing external windows and external walls, because they are the places with the greatest cold radiation intensity in the room. The air radiator first heats the air in the coldest area of ​​the room, and then relies on the radiation and convection of the heating to gradually heat the indoor air. The whole room forms basically the same stable temperature field, so living will be more comfortable. If the heater is installed on the inner wall of the room, it will produce an uncomfortable feeling, because the air radiator first heats the relatively high-temperature inner air, and then heats the cold air outside the room, forming a temperature field that is hot inside and cold outside, which is not suitable for people’s normal feeling. Warm habit. So what are the precautions when installing the air radiator, let’s introduce it in detail:

1. Check the integrity of the air radiator before installation, and unscrew the pipe buckle and screw plug;

2. The pipe connecting the air radiator (water pipe and steam pipe) should be the same size as the inlet and outlet pipe joints of the radiator, and the pipe cannot be used to support the radiator;

3. When the air radiator uses steam as the heat medium, the steam is introduced into the fan about ten minutes before the start of the fan, which is to preheat the radiator, so as to prevent the steam from suddenly entering the cold radiator and producing a large amount of condensed water, which will impact the equipment;

4. When the air inlet pipeline of the air radiator is directly connected to the outdoor, a blocking device should be installed at the air inlet to prevent the radiator from being frozen when it stops working;

5. Before installation, it should be clearly seen that the end of the steam inlet pipe is the end of the finned tube with shrinkage holes;

6. A steam trap should be installed at the end of the return water pipe, and the drainage volume of the steam trap should exceed 3 to 4 times of the condensed water of the radiator;

7. The air radiator should be equipped with the corresponding heat medium piping system according to the architectural design. Note that a gate valve should be installed on the steam or hot water pipeline and on the return water pipeline; when heating with steam, a condensate drain should be installed on the condensate pipeline. When several radiators are used in combination, it is best for each of them to be able to control its steam inlet, air release and return pipe devices individually, especially when the air is used in series in the air flow.
