Abstract
An indoor air quality system is configured to improve indoor air quality conditions within a local environment of a building. The indoor air quality system operates according to a method that includes obtaining indoor air quality levels and operating one or more appliances to adjust the indoor air quality levels.
Claims15
A method of controlling air quality within a local environment of a structure comprised of one or more rooms, the method comprising:
- placing one or more monitoring devices in the local environment,
- determining a dew point level of the local environment,
- determining whether or not the dew point is equal to or greater than 60° F. (15° C.),
- if the dew point is determined to be equal to or greater than 60° F. (15° C.), then measuring the continuous time over which the dew point stays equal to or greater than 60° F. (15° C.), and
- comparing the measured time to a threshold time and triggering a responsive action if the measured time is equal to or greater than the threshold time.
A method of controlling air quality within a local environment of a structure comprising two or more rooms, the method comprising:
- placing one or more monitoring devices in two or more of the rooms of the local environment,
- determining a dew point level in of the two or more rooms,
- determining whether or not the dew point is equal to or greater than 60° F. (15° C.) in each of the two or more rooms,
- setting a first threshold time for a first of the two or more rooms and second threshold time for a second of the two or more rooms,
- if the dew point is determined to be equal to or greater than 60° F. (15° C.) in the first of the two or more rooms, then measuring the continuous time over which the dew point stays equal to or greater than 60° F. (15° C.) in the first room and comparing the measured time for the first room to the first threshold time and triggering a responsive action if the measured time for the first room is equal to or greater than the first threshold time, and
- if the dew point is determined to be equal to or greater than 60° F. (15° C.) in the second of the two or more rooms, then measuring the continuous time over which the dew point stays equal to or greater than 60° F. (15° C.) in the second room and comparing the measured time for the second room to the second threshold time and triggering a responsive action if the measured time for the second room is equal to or greater than the second threshold time.
A method of controlling air quality within a local environment of a structure, the method comprising:
- placing one or more monitoring devices in the local environment of the structure comprised of one or more rooms,
- determining a dew point level of the local environment,
- determining whether or not the dew point is equal to or greater than 60° F. (15° C.),
- determining the dew point of air outside the structure,
- determining whether or not the dew point of the outside air is equal to or greater than 60° F. (15° C.),
- if the dew point of the local environment and the dew point of the air outside the structure are both determined to be equal to or greater than 60° F. (15° C.), then triggering a responsive action if the measured time is equal to or greater than the threshold time.
