What does the cooling turbine do?

The cooling turbine plays a crucial role in the air conditioning systems of aircraft by supercooling the air, bringing it to near-freezing temperatures. This process is essential for creating comfortable cabin conditions as it helps control the temperature and humidity levels during flight. By reducing the air temperature significantly, the cooling turbine ensures that the air entering the cabin is adequately cooled, allowing for effective temperature management and enhanced passenger comfort.

This function is particularly important in high-altitude flights where outside temperatures are extremely low, and the cabin air must be conditioned appropriately. The supercooling effect achieved by the cooling turbine helps in maintaining an optimal environment within the aircraft cabin, counteracting the heat generated by various sources including passengers, electronics, and the aircraft systems themselves.
