Question: 1 / 400

What is the primary function of the evaporator in a freon cooling system?

Lower the temperature of the cabin air

The primary function of the evaporator in a freon cooling system is to lower the temperature of the cabin air. In this cooling process, the evaporator plays a crucial role by allowing the refrigerant (freon) to absorb heat from the air inside the cabin. As the warm cabin air passes over the evaporator coils, the refrigerant inside evaporates, changing from a liquid to a gas. This phase change effectively absorbs heat, leading to a drop in air temperature before it is released back into the cabin.

This process is vital for maintaining a comfortable environment in the aircraft. While the evaporator also contributes indirectly to controlling the air's temperature and can influence how well the system regulates air supply, its primary and most critical function is focused on the cooling effect achieved by heat absorption.
