Study into the efficiency of additive infrared heating of industrial buildings in areas with low outside temperatures

Heating of industrial buildings is a complex and labor-consuming task requiring major financial investments. The complexity of this task grows in the case of large-size construction objects and strict requirements to their reliability, economic performance, and energy efficiency. The problem is even more complicated in those Russian regions, where low temperatures remain for a longer period of time. Significant financial investments are caused by the wear and obsolescence of the existing heating systems, leading to enormous heat losses. Due to the large size of the considered property types, it is difficult to select heating equipment that could provide the required temperatures inside the building while meeting all the aforementioned requirements. The solution can be found in the currently popular industrial infrared heaters, which provide both uniform heating of the building or room in question under significant energy savings. The application of infrared heaters as the main heating system equipment makes it possible to organize zonal (additive) heating of buildings of any type and purpose allowing different air temperatures even inside a single room. In this paper, a numerical study of the efficiency of additive heating systems with gas infrared emitters was carried out using a warehouse building as an example. Based on the analysis of the obtained results, the economic justification of the proposed technical solution was provided.
