Abstract
An indoor air quality (IAQ) system for a building includes a relative humidity (RH) sensor. The RH sensor is configured to measure a RH of the air within the building. At least one of a thermostat and an IAQ control module is configured to control humidification of the building based on the RH measured by the RH sensor.
Claims26
A humidifier control system for a building, comprising:
- an IAQ sensor module that is located within the building and that comprises:
- a particulate sensor configured to measure an amount of particulate of at least a predetermined size present in air at the IAQ sensor module;
- a volatile organic compound (VOC) sensor configured to measure an amount of VOCs present in air at the IAQ sensor module;
- and
- an average module configured to determine an average relative humidity (RH) of air within the building;
- an IAQ score module configured to determine an IAQ score value for air within the building based on the amount of particulate, the amount of VOCs, a RH of air within the building, and a temperature of air within the building;
- and
- a humidifier control module configured to selectively open and close a water feed valve of a humidifier within the building based on the IAQ score value and the average RH.
