Beschreibung
Zusammenfassung:	The invention relates to an air preparation system and an aircraft comprising the same. The air preparation system comprises an engine bleed air branch, a cabin exhaust branch, a compressor, a one-way valve and a main heat exchanger. Wherein the engine air entraining branch is used for pumping air from an air entraining main pipe to supply the air to a compressor or a one-way valve, an air preparation system pressure regulating valve is arranged on the engine air entraining branch, and the cabin exhaust branch is used for pumping air from a cabin exhaust area to supply the air to the compressor or the one-way valve. A cabin exhaust supply valve is arranged on the cabin exhaust branch, the one-way valve and the compressor are arranged in parallel, the main heat exchanger is arranged on the downstream of the compressor and the one-way valve and is in fluid communication with the compressor and the one-way valve, and the main heat exchanger is used for adjusting the temperature of air from the compressor or the
