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.
Claims18
An indoor air quality (IAQ) system for a building, comprising:
- a temperature sensor configured to measure a temperature of air within the building;
- a relative humidity (RH) sensor configured to measure a RH of the air within the building;
- and
- at least one of a thermostat and an IAQ control module configured to, during cooling of the air within the building, based on the RH, control operation of:
- a blower of an air handler unit of a heating, ventilation, and air conditioning (HVAC) system of the building;
- and
- a compressor of a condenser unit of the HVAC system of the building,
- wherein the at least one of the thermostat and the IAQ control module is configured to, while the compressor is off:
- operate the blower at a first predetermined speed when the RH is less than a first predetermined RH but greater than a second predetermined RH;
- and
- operate the blower at a second predetermined speed that is greater than the first predetermined speed when the RH is less than the second predetermined RH.

An indoor air quality (IAQ) control method for a building, comprising:
- by a temperature sensor, measuring a temperature of air within the building;
- by a relative humidity (RH) sensor, measuring a RH of the air within the building;
- and
- by at least one of a thermostat and an IAQ control module, during cooling of the air within the building, based on the RH, controlling operation of:
- a blower of an air handler unit of a heating, ventilation, and air conditioning (HVAC) system of the building;
- and
- a compressor of a condenser unit of the HVAC system of the building,
- wherein the control includes, while the compressor is off:
- operating the blower at a first predetermined speed when the RH is less than a first predetermined RH but greater than a second predetermined RH;
- and
- operating the blower at a second predetermined speed that is greater than the first predetermined speed when the RH is less than the second predetermined RH.
