Implementation Of New A/C System In Air-Plane Cabin

There are three situations used to provide cooling air for both flight deck equipment and the main equipment centre compartment racks in the aircraft, the first one is in flight operations: Since the bleed of air supply is always at higher temperature than what is required for the passenger comfort, a means of cooling this air is accomplished in flight by a simple air-to-air heat exchanger; this heat exchanger uses ambient ram air as a heat sink. (to reduce the heat). The second one during ground services: When an air plane is at ground being prepared for the next flight, a moveable air-conditioning system servicing from under the fuselage centre section to meet user system demands. And the third one when the ground services complete, the moveable air conditioning system will be disconnected and then the airplane will be moved to the run way for the departure. This means that it is a critical duration of time because there is no air conditioning is provided to the seating area of the passengers and the temperature of the area will raise to about (90°F) and 85% humidity. It is more critical if this duration of time will be longer which means a higher temperature will be, and leads to passengers discomfort as the pilot will not be able to provide any A/C to the passenger till the airplane is in flight operation.So this paper provides a full study and analysis that leads to develop a new air conditioning system for Aircraft (A320), which can be operated while the aircraft is at the gate or during the critical time between the end of ground service and take off. The successful development of the concept could create a new industry within the Middle East. To achieve the aim of this study, AC load determination, Air craft structure, zones, existing AC system description, ventilation system and pressurization system are needed to make a full study on the required design condition.
