What is Hybrid Chimney or Solar Chimney?
Solar chimney is the natural way of keeping any building cool.It is device build for natural ventilation.It consists of black colored chimney,inlet and outlet air aperture.
How it works?
When the air inside the chimney is heated, it rises up and come out from the chimney and as a result of this process, cold air pulls out from under the ground via the heat exchange tubes.
We all know that soil below the ground is much cooler than surrounding environment. According to my information when temperature above the ground is around 35 degree C, temperature below the ground is 12 degree Celsius.Now when connect underground pipe( as shown in figure) to the building it automatically become source of cold air. When air inside the chimney gets hot from the sun light, it starts rising, which create hollow space inside the chimney , to fill that space cold air is sucked inside the chimney naturally. This process of natural ventilation keeps on working until sunlight is available and this makes this very useful project.
