Season and amount of heated air
Thread Content
Is there a direct relationship between season and the air volume of the heating system? The air intake in summer is smaller than in winter; how can this be explained?
The main reason is that the atmospheric pressure varies throughout the seasons.
In summer, the temperature in the flue is high, and the oxygen content in the flue corridor is low; as a result, the buoyancy generated by the heating system is reduced, negative pressure appears at the viewing ports, and the lateral pressure distribution in the combustion chamber changes. Therefore, it is necessary to maintain relatively large air inlets. To keep the α value constant and increase the static pressure at the furnace head, the suction force should be kept low. The opposite is true in winter.
In summer, the temperature of the air entering the furnace is high, which allows some heat to be brought in (compared to winter). Moreover, the ambient temperature is high in summer, resulting in lower heat losses from the furnace. Therefore, when the heating furnace provides the same amount of heat, the consumption of fuel gas is slightly lower in summer, and thus less air is required as well. That’s what I think: P. I’m not sure if it’s correct I also ask fellow sailors for their feedback!
Thanks. No points can be added today; let’s do it next time.
Obviously, there is a connection; this is mainly due to the different levels of air density. It’s a simple principle – summer and winter are similar to hot air and cold air, and the suction force varies accordingly. The difference in density leads to changes in suction force; thus, the difference between the air density in summer and the density of the exhaust gases inside the chimney is smaller than the difference between the air density in winter and the density of the chimney’s exhaust gases. Thus, the chimney suction in summer is less than that in winter. All of the explanations mentioned above can be found in the materials on aerodynamic fluid mechanics, where the final answers can be obtained
