Abstract
An environmental control system for an aircraft includes a first inlet configured to receive recirculation air from a cabin of the aircraft, a second inlet configured to receive fresh air and a manifold for mixing the recirculation air with the conditioned fresh air to form mixed air. The ECS further includes a contaminant removal system configured to remove contaminants from the mixed air to form cabin air and an outlet configured to supply the cabin air to the cabin. The ECS further includes a controller configured to receive air quality information from an air quality sensor, the controller configured to control the contaminant removal system based on the air quality information.
Claims14
An environmental control system for an aircraft, the environmental control system comprising:
- a first inlet configured to receive recirculation air from a cabin of the aircraft;
- a second inlet configured to receive fresh air;
- a manifold for mixing the recirculation air with the conditioned fresh air to form mixed air;
- a contaminant removal system configured to remove contaminants from the mixed air to form cabin air;
- an outlet configured to supply the cabin air to the cabin;
- and
- a controller configured to receive air quality information from an air quality sensor, the controller configured to control the contaminant removal system based on the air quality information.
An environmental control system according to claim 10, wherein the contaminant system comprises a second regenerative filter, wherein the first and second regenerative filters share a common inlet to receive regeneration air.
An environment control system according to claim 10, further comprising:
- a heat recovery unit, the heat recovery unit configured to recover heat from exhaust air exhausted from the first regenerative filter, optionally, wherein the recovery unit is configured to heat regeneration air.
A contaminant removal system for an environmental control system for an aircraft, the contaminant removal system configured to:
- receive mixed air from a manifold of the environmental control system, the manifold configured to mix recirculation air from a cabin of the aircraft with conditioned fresh air to form the mixed air;
- remove contaminants from the mixed air to form cabin air;
- and
- supply cabin air to the cabin, the contaminant removal system comprising a controller configured to receive air quality information from an air quality sensor, the controller configured to control the contaminant removal system based on the air quality information.
A method of controlling an aircraft environment, the method comprising:
- receiving recirculation air from a cabin of the aircraft;
- receiving conditioned fresh air;
- mixing the recirculation air with the conditioned fresh air to form mixed air;
- receiving air quality information;
- controlling a contaminant removal system, based on the air quality information, to remove contaminants from the mixed air to form cabin air;
- and
- supplying the cabin air to the cabin.
