In recent years, building energy consumption has increased rapidly, especially the heating of some tall space buildings consumes a lot of energy. How to use energy efficiently to cope with the rapid growth of building construction, especially in the field of tall space heating and building energy efficiency? In order to save energy and reduce energy loss, it is necessary to seek effective means to reduce heat loss in energy consumption. Therefore, the development of improved means of heat transfer, especially the use of radiation heating, is a very important aspect of energy conservation in buildings, especially in tall Spaces. 
 

	As we all know, the traditional convection method and the ineffective heat loss of the upper part of the building can not be ignored in winter heating, because of the use of this method in a large space, wide doors and Windows, high space, large span, large thermal conductivity, and the upper part of the large space building in order to meet the needs of ventilation and structure, almost all have an opening, causing serious energy waste in winter heating. In addition, the indoor temperature gradient is large, and the stratification is serious, resulting in a large temperature difference between indoor and outdoor, and the phenomenon of hot and cold indoor air. In addition, due to the difference in density, the hot air will rise, causing most of the energy to be wasted.

 

	According to the literature, when the production hall, maintenance warehouse and other tall space buildings adopt radiation heating, the indoor height gradient becomes very small. Gas radiant heating is becoming a common solution for tall Spaces and is considered to be more energy efficient than traditional convection heating systems, reducing energy consumption by about 30-50%.

When the radiation heating is used, the actual perceived temperature in the building can be reduced by about 2-3 degrees compared with the heat convection heating, which reduces the heat consumption of the building. The switch of radiant heating system is completely controlled by computer. It can be realized that only a few radiation tubes are opened when individual stations work overtime, and other radiation tubes are automatically closed, that is, regional heating and regular heating. Therefore, the performance of radiation heating can be considered as the most effective way of heating tall Spaces. 
 
IMPRESIND gas radiant heating system is the main heating equipment of Beijing Leadway Power Co., LTD. The heat generator is installed on the roof or side wall outside the building, and the radiation tube is installed on the upper part of the heating space of the building. The installation period is short, and the use area of the building is not occupied, saving valuable building land. The heat propagation of gas radiant heating has strong directivity. It can be flexibly arranged according to different needs, can carry out comprehensive heating, and can also be heated in a large space in a local area. In addition, the insulation conditions of the maintenance structure of the tall space building are not high, and the tall space can be heated on demand, which is not possible for convective heating.
