Which section of a turbine engine is used for pressurization and air-conditioning systems?

The compressor section of a turbine engine is responsible for pressurization and air-conditioning systems. This section increases the pressure of the incoming air before it enters the combustion chamber. The compressor compresses the ambient air, which results in higher temperature and pressure.

The pressurized air can then be utilized not only to support the combustion process but also to provide bleed air for various aircraft systems, including cabin pressurization and air conditioning. This is crucial for maintaining a comfortable and safe environment for passengers and crew at high altitudes where ambient air pressure is significantly lower.

In contrast, other sections of the turbine engine serve different functions. The exhaust section deals primarily with the expulsion of combustion gases, while the combustion section is focused on the burning of fuel and air mixture. The expansion section, often referred to in the context of turbines, converts the energy from the high-pressure gases to work, driving the turbine. Therefore, while all sections are vital for engine performance, the compressor section specifically fulfills the role related to pressurization and air conditioning.
