Abstract

An environmental control system (ECS) includes a controller; and a mode selector in communication with the controller and configured to select at least one of a plurality of modes. The mode is based on one of: number of occupants in an environment; activity of the occupants in the environment; destination of the environment; and performance of an engine that moves the environment. The controller is configured to change an ECS load on the system based upon the selected mode.

First claim

We claim:

1. A non-transitory computer-readable medium for an environmental control system (ECS) of a vehicle an aircraft comprising instructions stored thereon, that when executed on a processor, performing steps of:
selecting at least one of a plurality of operating modes, wherein the at least one of the plurality of operating modes is based on a distance to a destination to be reached by an environment;
changing, based on the selected at least one of the plurality of operating modes at least one of:
a load on the ECS;
a ventilation valve enabling flow into the environment; and
an outflow valve enabling flow out of the environment.

2. The non-transitory computer-readable medium of claim 1 , wherein another operating mode is based on an occupancy of the environment and the occupancy is an occupancy number threshold.

3. The non-transitory computer-readable medium of claim 1 , wherein another operating mode is based on an occupancy of the environment and the occupancy is an occupancy activity threshold.

4. The non-transitory computer-readable medium of claim 1 , wherein the environment includes a first environment and a second environment.

5. The non-transitory computer-readable medium of claim 4 , wherein the ventilation valve is intermediate the first and second environments.

6. The non-transitory computer-readable medium of claim 4 , wherein the first environment is an aircraft cabin and the second environment is an aircraft cockpit.
