The present invention relates to an air quality monitoring and controlling system and method for enclosed spaces, which provides an innovative closed loop (i.e., inline real time feedback) air management process, utilizing learning and prediction capabilities to provide with effective air purification and reliable alerting when required.

A ventilation system with: (i) a volumetric enclosure having an inlet and an outlet and for coupling to an interior of a building habitable by human occupants; (ii) a fan located within the volumetric enclosure and for drawing air exterior to the building and supplying the air to the interior of the building; (iii) a programmable control apparatus for enabling and disabling the fan in response to a plurality of parameters, at least some of the parameters relating to quality of air to me moved in response to the fan; and (iv) circuitry coupled between the inlet and the outlet for measuring a signal representative of a volume of air passing through the volumetric enclosure over a period of time.

An air purifier system includes at least one air purifier and a portable user interface device. The user interface device for positioning at a remote location from the at least one air purifier and wirelessly communicated to a controller of at least one of the air purifiers. The user interface device includes a sensor configured to measure an air quality parameter in an area proximate the user interface device for transmission of the air quality parameter to the controller of the at least one of the air purifiers via wireless communication; and a user interface comprising (a) a display for displaying data including at least air quality data from the sensor and (b) a user input control for the user to change one or more functional parameters of the at least one of the air purifiers via the wireless communication.

In various embodiments, an air quality-monitoring system (100) may include at least one sensor (106) configured to detect operation of a mechanism (110) within or at a boundary of an indoor environment. The mechanism may be external to an air purifier (102) associated with the indoor environment. The system may include a persistent memory (124) for storing data about the indoor environment observed by the at least one sensor (106). A controller (104) may be communicatively coupled with the at least one sensor and configured to: assemble the data into an air quality profile associated with that environment; determine, based on a signal from the at least one sensor and on the air quality profile, a likelihood that operation of the mechanism will cause a measure of air quality within the indoor environment to fail one or more air quality criteria; and selectively provide, based on the likelihood, an indication that operation of the mechanism will cause the measure of air quality within the indoor environment to fail the one or more air quality criteria.

An air purifying system includes an air purifier mechanism, a controller, and a sensing device. The sensing device is configured to measure an air quality parameter of the air entering the housing via the air inlet to generate inlet air quality data, and to measure an air quality parameter of the purified air exiting the housing via the air outlet to generate outlet air quality data. The controller is configured to: receive the inlet air quality data and the outlet air quality data, compare the inlet air quality data and the outlet air quality data with their corresponding predetermined threshold ranges, and determine an action to be taken.
