Abstract
A system and method for air quality control system for an air-conditioning device. The air quality control system includes a housing having an inlet end to receive a source airflow from the air-conditioning unit and an outlet end to provide a sanitized airflow. The system also includes a number of independently controllable air sanitizing components coupled to the housing. The system further includes a controller to adaptively control which of the air sanitizing components should operate as a function of at least an operating state of the air conditioning unit.
Claims49
An air quality control system for use with an air-conditioning unit, the air quality control system comprising:
- a housing having an inlet end to receive a source airflow from the air-conditioning unit and an outlet end to provide a sanitized airflow;
- at least one germicidal lamp disposed within the housing to generate ultraviolet radiation within the source airflow;
- at least one ozone lamp disposed within the housing to generate ozone gas within said source airflow;
- and
- a controller to adaptively control emission of the ultraviolet radiation and ozone gas within said source airflow as a function of at least an operating state of said air conditioning unit,
- wherein operation of said air quality control system is electrically and mechanically independent from said air conditioning unit.
An air quality control system comprising:
- a user interface to receive user input relating to the control of air quality in said air quality control system;
- a housing having an inlet end to receive a source airflow and an outlet end to provide a sanitized airflow;
- at least one germicidal lamp coupled to the housing to generate ultraviolet radiation into the source airflow;
- at least one ozone lamp coupled to the housing to generate ozone gas into the source airflow;
- an ozone sensor coupled to the housing to sense an ozone gas level within the source airflow;
- and
- a controller to adaptively control emission of the ultraviolet radiation and the ozone gas into the source airflow in accordance with said user input and as a function of at least said ozone gas level and the source airflow.
The system according to claim 25, wherein said controller is further configured to control operation of said at least one ozone lamp based on said excess quantity of ozone within said source airflow.
A method for controlling air quality in a ventilation system including an air-conditioning unit and an air distribution network, the method comprising:
- receiving user supplied input relating to the control of air quality within said ventilation system;
- determining an operating state of the air conditioning unit;
- determining an ozone level within a source airflow generated by said air conditioning unit;
- determining an odor level within said source airflow;
- and
- adaptively exposing at least a portion of the source airflow to at least one of an ozone gas and ultraviolet radiation as a function of at least said operating state of the air conditioning unit and said ozone gas level so as to generate a sanitized airflow for provision to the air distribution network in accordance with said user supplied inputs.
A modular air quality control system for use with an air-conditioning unit, the air quality control system comprising:
- a housing having an inlet end to receive a source airflow from the air-conditioning unit and an outlet end to provide a sanitized airflow;
- a plurality of independently controllable air sanitizing components coupled to the housing;
- and
- a controller to adaptively control which of said plurality of independently controllable air sanitizing components should operate as a function of at least an operating state of said air conditioning unit.
A modular air quality control system for use with an air-conditioning unit, the air quality control system comprising:
- a housing having an inlet end to receive a source airflow from the air-conditioning unit and an outlet end to provide a sanitized airflow;
- at least one air sanitizing component coupled to the housing;
- and
- a controller to adaptively control operation of said at least one air sanitizing component based on a presence or absence of said source airflow, wherein operation of said air quality control system is electrically and mechanically independent from that of said air conditioning unit.
