Abstract

Provided are methods for decontamination of compartments, such as aircraft compartments and other types of compartments, and systems for implementing these methods. In some embodiments, a method involves detecting presence of one or more contaminants in a compartment. This information is used to select various decontamination conditions. In some embodiments, additional information, such as the type of the compartment (e.g., an aircraft compartment), temperature, and humidity, may be also considered while selecting the decontamination conditions. The decontamination conditions include identification of one or more decontaminating agents to be dispensed in the compartment, temperature profile of the air to be flown into the compartment, and timing of the decontaminant dispensing and air flowing operations. These conditions are selected to increase efficacy of the selected decontaminating agents with respect to the one or more detected contaminants and reduce impact on the aircraft compartment.

First claim

What is claimed is:

1. A system for decontamination of a compartment, the system comprising:
a controller for selecting decontamination conditions for use in the compartment based on presence of one or more contaminants,
wherein the decontamination conditions comprise at least
a decontaminating agent for dispensing in an aerosolized form in the compartment,
an operating temperature of a heated air for flowing through the compartment during the decontamination, and
a relative timing of dispensing the decontaminating agent and flowing the heated air;

a decontaminating agent dispenser for dispensing the decontaminating agent in the aerosolized form in the compartment;
an air heater for heating the air to the operating temperature; and
an air blower for flowing the heated air through the compartment,
wherein the operating temperature is selected for efficacy of the decontaminating agent with respect to the one or more contaminants.

2. The system of claim 1 , wherein the decontaminating agent dispenser comprises one or more nozzles for dispensing the decontaminating agent, and wherein the decontaminating agent dispenser further comprises an electrostatic charging system connected to the one or more nozzles for applying an electrostatic charge to the decontaminating agent as the decontaminating agent is dispensed.

3. The system of claim 1 , wherein at least a portion of the system is integrated into an aircraft, and wherein at least a different portion of the system is separate from the aircraft.

4. The system of claim 1 , wherein the decontaminating agent dispenser is configured to dispense the decontaminating agent into an air flow provided by the air blower.

5. The system of claim 1 , further comprising a biological sensor, a chemical sensor, a temperature sensor, and a humidity sensor coupled to the controller.

6. The system of claim 5 , wherein the biological sensor comprises a bio-recognition component and a bio-transducer component.

7. The system of claim 5 , wherein the chemical sensor is one of a catalytic bead sensor, a chemical field-effect transistor, an electrochemical gas sensor, an infrared point sensor, or an ion-selective electrode.

8. The system of claim 1 , wherein the controller is configured to select the decontamination conditions further based on a humidity in the compartment and based on a temperature in the compartment.

9. The system of claim 1 , further comprising a humidifier for controlling humidity of the heated air flowing through the compartment.

10. The system of claim 1 , further comprising a filtration component for capturing the one or more contaminants and the decontaminating agent removed from the compartment.

11. The system of claim 1 , wherein the air heater and the air blower are parts of an aircraft ventilation system.

12. The system of claim 11 , wherein the controller is communicatively coupled to an aircraft ventilation system and configured to direct operations of the aircraft ventilation system during the decontamination of the compartment.

13. The system of claim 11 , wherein the decontaminating agent dispenser is positioned within the aircraft ventilation system for dispensing the decontaminating agent in the aerosolized form in the compartment through the aircraft ventilation system.

14. The system of claim 1 , wherein the decontaminating agent dispenser is a cart rollable through an aisle of an aircraft cabin.

15. The system of claim 1 , wherein the operating temperature is selected to minimize duration of the heated air flowing through the compartment.

16. The system of claim 1 , wherein the operating temperature is selected to minimize a concentration of the decontaminating agent.

17. The system of claim 1 , wherein the decontamination conditions further comprise a temperature ramping profile.

18. The system of claim 17 , wherein the temperature ramping profile is linear.

19. The system of claim 1 , wherein the operating temperature is between about 100 degrees Fahrenheit and 180 degrees Fahrenheit.

20. The system of claim 1 , wherein the opera temperature is between about 120 degrees Fahrenheit and 140 degrees Fahrenheit.
