This ARP discusses design philosophy, system and equipment requirements, and ambient conditions and design considerations for systems within the ATA 100 Specification, Chapter 21. This chapter is principally concerned with passenger and crew environment and the air conditioning system that maintains this environment. The airplane air conditioning system comprises that arrangement of equipment, controls and indicators that supply and distribute air to the occupied compartments for ventilation, pressurization, and temperature and moisture control. The principal features of the system are: a. a supply of fresh air from at least two sources with independent control valves; b. a means for heating; c. a means for cooling (air or vapor cycle units and heat exchangers); d. a means for removing excess moisture from the air supply; e. a ventilation subsystem; f. a temperature control subsystem; and g. a pressure control subsystem. Other system components for treating cabin air such as filtration and humidification would be included, as would the ancillary functions of equipment cooling and cargo compartment conditioning. The interface with the major associated system, the pneumatic system, is at the inlet of the air conditioning shutoff valves. This boundary definition aligns with that in the ATA 100 Specification.
