Abstract
The present invention provides an environmental control system for an aircraft attendant or crew rest ventilation system. The system provides primary and secondary sources of air to the crew or attendant rest. A pressure sensor within the supply duct determines whether air from the primary duct is within desired pressure limits and controls operation of the ducts accordingly. Additional features related to temperature control and ventilation are also provided.
Claims14
An environmental control system for a rest area in an aircraft, comprising:
- a first air source configured to supply a first volume of air;
- a first air duct arranged to receive the first volume of air from the first air source and deliver it to the rest area;
- a sensor configured to determine the amount of the air traveling through the first air duct;
- a second air duct connected to the first air duct and configured to deliver a second volume of air to the rest area via the first air duct;
- a valve within the second air duct;
- and
- a system controller in communication with the pressure sensor and the valve, whereby when the sensor indicates that the amount of the air traveling through the first duct is below a desired level, the system controller causes the valve to open a sufficient degree to enable at least a portion of the second volume of air to flow to restore air flow above the desired level.
