Abstract: Environmental control system (ECS) in aircraft provide comfortable environment for people and goods. The temperature, pressure and humidity are vital properties of indoor air in aircraft. In this study, the systems used for conditioning the indoor air of the aircraft are considered. The hot and pressurised air that came from the compressor of the engine is transferred to the cabin by changing some of its characteristics. Thus, the indoor air quality is controlled. This study analyses the ECS in aircraft. Some of these systems are cabin air conditioning, pressurisation, humidity control and temperature control. When investigating these systems, some important values were obtained for ensuring the comfort and safety in the aircraft. Fresh air renewal period, strength for the skin panel, humidity formed in the cabin and heating demand were found to be 443 s, 84.8 kN/m², 0.6 g/kg and 106.2 kW, respectively.

Keywords: indoor air quality; aircraft environmental control systems; indoor air conditioning.
