Heating System Simulation – Part 3 of 4

RESULTS OF THE SIMULATION – WITH RADIATORS

In this new blog post, we will show the results obtained from simulating the heating system with radiators.
In the image below, you can see a cut at the height of the beds which is about 50 centimeters above the floor.

As you can see, there are quite a few cold spots of air except in the areas near the radiators. You can also observe how the temperature is lower in the living room than in the other rooms. This is because it is the area with the largest volume of air to heat.

In the photo above, a cut made at 2 meters high is shown. The situation changes remarkably. At this height the average temperature is about 3 degrees higher and you can see the hot air spots from the radiators.

This already gives us an idea of the mechanism of heating by the radiators.

In the next image, you can see perfectly how the convection is generated by radiators. The convection resulting from a radiator can be seen in all its splendor.

The cold air in the lower area of the room heats up when it encounters the radiator and goes up to the ceiling, cooling down progressively.

This creates a stratification of temperatures, which is not a desirable phenomenon for comfort levels.

Convection from radiators

Below are comparisons between the floor renderings provided by Quilding and the simulations carried out by Ingeniacity with OpenFOAM® software.

The current lines clearly show how there are two distinct areas—hot air at the ceiling and cold air at the floor—and how the air moves around the surrounding areas.
