Abstract
An air cycle system for use in a vehicle having an internal combustion engine is provided. A compressor has an outflow to an intercooler with an outflow to a first bypass valve. The first bypass valve has an open and a closed orientation, directing air to the engine of the vehicle in the open orientation and directing air to an expander in the closed orientation. The expander has an outflow to a second bypass valve that is adjustable so it can direct a variable fraction of air to the engine and the remainder of the air to an air handling unit. The air handling unit has at least a fan, a scroll center, and first and second air flow paths. The first air flow path has an input at the scroll center from the second bypass valve and the second air flow path has an input at the fan from the interior of the vehicle. The air handling unit mixes air from the first and second flow paths and directs the mixed air to the interior of the vehicle.
