Abstract
A vehicle includes a first area conditioned by a first medium, a second area conditioned by a second medium, and an air management system. The air management system includes a source of third medium, an environmental control system fluidly coupled to the source of third medium and to the second area, and a closed loop vapor compression system having a refrigeration medium circulating therein. The vapor compression system is fluidly coupled to the first area, the second area, and the source of third medium. During normal operation, both a first flow of the third medium conditioned within the environmental control system and a second flow of the third medium are provided to the second area.
Claims20
A vehicle comprising:
- a first area conditioned by a first medium;
- a second area conditioned by a second medium;
- and an air management system including:
- a source of third medium, the third medium being separable into a plurality of parallel flows including a first flow of the third medium and a second flow of the third medium;
- an environmental control system fluidly coupled to the source of third medium and to the second area, wherein an inlet of the environmental control system is arranged downstream from and is configured to receive the first flow of the third medium, and a closed loop vapor compression system having a refrigeration medium circulating therein, the vapor compression system being fluidly coupled to the first area, the second area, and the source of third medium;
- a mixing unit fluidly connected to an inlet of the second area;
- wherein during normal operation, both the first flow of the third medium conditioned within the environmental control system and the second flow of the third medium are provided to the second area, and the second flow of the third medium is mixed with the second medium at a location upstream from the mixing unit.
An air management system comprising:
- an area to be conditioned by at least one of a first medium and a second medium;
- a first system fluidly coupled to the area to be conditioned;
- and
- a second system fluidly coupled to the area to be conditioned;
- wherein a first portion of the first medium is provided to the area to be conditioned from the first system and a mixture of the second medium and a second portion of the first medium separate from the first portion of the first medium, is provided to the area to be conditioned from the second system, wherein a pressurization of the first portion of the first medium is selected to meet a pressurization demand of the area and a temperature of the mixture of the second medium and the second portion of the first medium is selected to meet a temperature demand of the area to be conditioned.
A vehicle comprising:
- a first area conditioned by a first medium;
- a second area conditioned by a second medium;
- and
- an air management system including:
- a source of third medium;
- an environmental control system fluidly coupled to the source of third medium and to the second area, and
- a closed loop vapor compression system having a refrigeration medium circulating therein, the vapor compression system being fluidly coupled to the first area, the second area, and the source of third medium, the vapor compression system having a heat exchanger fluidly connected to and arranged downstream from an outlet of the first area and an outlet of the second area, wherein the first medium output from the first area and a fourth medium output from the outlet of the second area are simultaneously conditioned within the vapor compression system;
- wherein during normal operation, both a first flow of the third medium conditioned within the environmental control system and a second flow of the third medium are provided to the second area.
