A ground cooling unit (GCU) for aircraft is a specialized piece of equipment designed to cool the interior of an aircraft while it is on the ground. These units are essential for maintaining a comfortable temperature inside the aircraft, especially in hot weather conditions, and for protecting sensitive onboard equipment from overheating.
Key Features and Components
Air Handling Unit (AHU): The AHU is responsible for the distribution of cooled air throughout the aircraft cabin.
Compressor: This component compresses the refrigerant, which is crucial for the cooling process.
Heat Exchanger: Transfers heat from the refrigerant to the outside air, allowing for the cooling process to occur.
Refrigerant: A fluid that absorbs and releases heat, facilitating the cooling process.
Control System: Allows for the precise regulation of temperature and airflow.
Power Supply: Usually connected to the airport’s power grid or a ground power unit .
