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 levels and operating one or more appliances to adjust the indoor air levels. The system includes one or more monitoring devices.

First claim

The invention claimed is:

1 . A system configured to dehumidify air within a local environment of a structure, the system comprising:
a plurality of monitoring devices configured to be located in the local environment of the structure comprised of one or more rooms of the structure, each monitoring device of the plurality of monitoring devices configured to be located in one of the one or more rooms, a processor configured to: determine a room humidity level for each of the one or more rooms with the monitoring device located in the corresponding one of the one or more rooms, assign a weight to the room humidity level determined for each of the one or more rooms where high-humidity events take place, calculate a total humidity level of the local environment based on the room humidity levels of each of the one or more rooms, wherein the calculating of the total humidity level includes averaging the weighted room humidity level in the local environment, and activate a dehumidification device to remove moisture from the air within at least some of the one or more rooms when (i) the total humidity level is above a predetermined threshold, and (ii) it is determined there are no localized, high humidity events in the local environment.

2 . The system of claim 1 , wherein the processor is further configured to activate a local exhaust fan in communication with the second room to remove moisture from the second room.

3 . The system of claim 1 , wherein the processor is configured to weight the room humidity level determined for each of the one or more rooms where high-humidity events take place according to manually entered user preferences to adjust the weighting of the room humidity level determined for each of the one or more rooms.

4 . The system of claim 1 , wherein the processor is configured to determine that a high-humidity event has occurred in a first room of the structure and adjust the room humidity value of the first room prior to calculating the total humidity level of the local environment.

5 . The system of claim 1 , wherein the processor is configured to obtain outdoor air quality index data and activate the dehumidification device to adjust at least one room humidity value based, at least in part, on the outdoor air quality index data.

6 . The system of claim 1 , wherein the processor is configured to obtain an outdoor dew point and an indoor dew point and if the outdoor dew point is greater than the indoor dew point, and the indoor dew point is greater than a predetermined threshold, the processor is configured to activate an exhaust fan and a supply fan together with the dehumidification device to remove indoor pollutants and decrease humidity within the indoor environment at the same time.

7 . A system configured to reduce humidity levels within a local environment of a structure, the system comprising:
a plurality of monitoring devices configured to be located in the local environment of the structure comprised of one or more rooms of the structure, each monitoring device of the plurality of monitoring devices configured to be located in one of the one or more rooms, a processor configured to: determine a room humidity level for each of the one or more rooms with the monitoring device located in the corresponding one of the one or more rooms, calculate a total humidity level of the local environment based on the room humidity level of each of the one or more rooms, and calculate an indoor dew point from the total humidity level, obtain an outdoor dew point, determine whether to activate a dehumidification device to remove moisture from the air within one or more of the one or more rooms based on the total humidity level, unless the outdoor dew point is within 10% of the indoor dew point, and determine to activate an exhaust fan and a supply fan together with the dehumidification device (i) if the outdoor dew point is greater than the indoor dew point and (ii) the indoor dew point is greater than a predetermined threshold, to remove indoor pollutants and decrease humidity within the indoor environment at the same time.

8 . The system of claim 7 , wherein the processor is further configured to weight the room humidity level determined for each of the one or more rooms.

9 . The system of claim 8 , wherein weighting the room humidity level includes determining that a first room of the local environment has a first humidity level within a range and determining that a second room of the local environment has a second humidity level outside of the range.

10 . The system of claim 8 , user preferences adjust the weighting of the room humidity level determined for each of the one or more rooms.

11 . The system of claim 7 , wherein the processor is further configured to determine that a high-humidity event has occurred in a first room of the structure and adjusting the room humidity value of the first room prior to calculating the total humidity level of the local environment.

12 . A system configured to improve humidity levels within a local environment of a structure, the system comprising:
a plurality of monitoring devices configured to be located in the local environment of the structure comprised of one or more rooms of the structure, each monitoring device of the plurality of monitoring devices configured to be located in one of the one or more rooms, a processor configured to: determine a room humidity level for each of the one or more rooms with the monitoring device located in the corresponding one of the one or more rooms, calculate a total humidity level of the local environment based on the room humidity level of each of the one or more rooms and calculate an indoor dew point from the total humidity level, obtain an outdoor dew point, determine whether to activate a dehumidification device to remove moisture from the air within one or more of the one or more rooms based on the total humidity level, if the indoor dew point is less than the outdoor dew point, and determine whether to activate an exhaust fan and a supply fan together with the dehumidification device (i) if the outdoor dew point is greater than the indoor dew point and (ii) the indoor dew point is greater than a predetermined threshold, to remove indoor pollutants and decrease humidity within the indoor environment at the same time.

13 . A system configured to improve humidity levels within a local environment of a structure, the system comprising:
a plurality of monitoring devices configured to be located in the local environment of the structure comprised of one or more rooms of the structure, each monitoring device of the plurality of monitoring devices configured to be located in one of the one or more rooms, a processor configured to: determine a room humidity level for each of the one or more rooms with the monitoring device located in the corresponding one of the one or more rooms, assign a weight to the room humidity level determined for each of the one or more rooms, determine whether to activate a local exhaust fan in communication with a second room of the local environment to remove moisture from the second room when (i) a first room of the local environment has a first humidity level within a range and (ii) the second room has a second humidity level outside of the range, calculate a total humidity level of the local environment based on the room humidity levels of each of the one or more rooms, wherein calculating the total humidity level includes averaging the weighted room humidity level in the local environment, and determine whether to activate a dehumidification device to remove moisture from the air within one
