DIRECT CONTACT LIQUID AIR CONTAMINANT CONTROL SYSTEM
First Claim
1. A method for providing environmental control for cabin air of a vehicle comprising the steps of:
- introducing a portion of the cabin air as air flow into a carbon dioxide scrubber; and
spraying a liquid mist into the air flow thereby modifying humidity, temperature and carbon dioxide concentration of the cabin air.

Abstract
An integrated environmental control system for cabin air of an aircraft or spacecraft. Humidity and temperature of cabin air are controlled with a direct contact liquid air contaminant control system that revitalizes cabin air by removal of carbon dioxide and other trace gas contaminants through use of a direct contact air, liquid scrubber element and stripper element. The scrubber element has two rotor elements rotatably mounted in a housing first for centrifugal separation of an air flow and liquid absorbent mixture which liquid absorbent has absorbed carbon dioxide and trace gas contaminants. Then second for centrifugal separation of an air flow and acid water wash mixture which acid water wash has liquid absorbent and other contaminants. The processed air is then passed through a charcoal bed filter for further removal of contaminants. A rotary contact processor may also be used to reprocess contaminated liquid absorbent for reuse.

9. An environmental control apparatus for cabin air of a vehicle comprising:
-
a contaminant scrubber wherein a contamination-control liquid is introduced as a mist into an air flow of a portion of the cabin air through the contaminant scrubber; the contamination-control liquid having a temperature lower than a temperature of the cabin air; and wherein temperature of the cabin air is reduced and humidity of the cabin air is modified. - View Dependent Claims (10, 11, 12, 13)
