Abstract
An aspirating smoke detection unit 1 for limiting the spread of airborne contaminants. The aspirating smoke detection unit 1 includes a smoke detector 5 for detecting the presence of smoke particles suspended in air from a monitored region; an ozone generator 7 for producing ozone from oxygen contained in air from the monitored region 20; and an ionizer 8 for ionizing air molecules within air from the monitored region 20. A methods of reducing the spread of airborne contaminants within a monitored region 20 using the aspirating smoke detection unit 1.
Claims13
An aspirating smoke detection unit (1) for limiting the spread of airborne contaminants, comprising:
- a smoke detector (5) for detecting the presence of smoke particles suspended in air from a monitored region (20);
- an ozone generator (7) for producing ozone from oxygen contained in air from the monitored region;
- and
- an ionizer (8) for ionizing air molecules within air from the monitored region;
- wherein the ionizer is configured to generate an ion density of at least 600,000 ions/cm3.
A method of reducing the spread of airborne contaminants within a monitored region (20) using an aspirating smoke detection unit (1), the method comprising:
- providing an aspiration smoke detection unit, wherein the aspiration smoke detection unit comprises an ozone generator (7) for producing ozone from oxygen contained in air, and an ionizer (8) for ionizing air molecules;
- passing air from the monitored region to the aspirating smoke detection unit;
- using the ozone generator to produce ozone from oxygen within the air from the monitored region, wherein the produced ozone acts to kill and/or neutralise pathogens within the air and provide purified air;
- using the ionizer to ionize air molecules passed to the aspirating smoke detector from the monitored region;
- passing the purified air into the monitored region;
- and
- passing ions generated by the ionizer into the monitored region for reducing and/or neutralising electric charge on surfaces in the monitored region.
