Abstract
An HVAC system within a building including an HVAC device having an air filter, a number of sensors, and a control device. The control device has a processor that is configured to determine a current air quality metric based on air quality measurements received by the sensor. The control device is further configured to calculate an average air quality metric based on the current air quality metric and a set of previous air quality metrics. The control device is further configured to store the average air quality metric. The control device is further configured to generate an air filter type recommendation based on the average air quality metric.
Claims20
A heating, ventilating, or air conditioning (HVAC) system within a building comprising:
- an HVAC device comprising an air filter;
- one or more sensors configured to measure air quality within the building, wherein the one or more sensors include at least one of a volatile organic compound (VOC) sensor, a carbon dioxide sensor, or a pollen sensor;
- and
- a control device comprising a processor and a memory, the processor configured to:
- determine an air quality metric, wherein the air quality metric is determined based on measurements received by the one or more sensors;
- and
- generate an air filter type recommendation based on the air quality metric.
A method for recommending filter types to be used in a system of a building comprising:
- obtaining, by one or more sensors, a measurement of air quality within the building;
- calculating, by a control device an air quality metric based on the measurement;
- comparing, by the control device, the air quality metric to a low threshold value;
- and
- generating, by the control device, an air filter type recommendation based on the air quality metric.
A thermostat, comprising:
- an interface configured to be coupled to a device comprising an air filter and one or more sensors configured to measure air quality within the building, wherein the one or more sensors include at least one of a volatile organic compound (VOC) sensor, a carbon dioxide sensor, and a pollen sensor;
- and
- a processor configured to:
- determine an air quality metric, wherein the air quality metric is determined based on measurements received by the one or more sensors;
- and
- generate an air filter type recommendation based on the air quality metric.
A heating ventilating, or air conditioning (HVAC) system within a building comprising:
- an HVAC device comprising an air filter;
- one or more sensors configured to measure air quality within the building;
- and
- a control device comprising a processor and a memory, the processor configured to:
- determine an air quality metric, wherein the air quality metric is determined based on measurements received by the one or more sensors;
- and
- generate an air filter type recommendation based on the air quality metric, wherein generate the air filter recommendation comprises determine a recommended filter from a plurality of filters of different restrictive airflow resistances based on a comparison of the air quality metric to a plurality of threshold values.
