Abstract
Methods, environmental control systems, and computer program products are provided for controlling an internal environment of a pressurized compartment of a vehicle. In one aspect, the pressurized compartment includes first and second exit valves for selectively allowing gas to exit the pressurized compartment. The first and second exit valves are located, respectively, in spaced apart portions of the pressurized compartment. The pressurized compartment also includes first and second systems that are located, respectively, in the spaced apart portions of the pressurized compartment. Flow rates of gases in the first and second systems are determined and at least one of the first and second exit valves is controlled in response to the flow rate determinations.
