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
An 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 a current air quality metric, wherein the current air quality metric is determined based on measurements received by the one or more sensors;
- calculate an average air quality metric based on the current air quality metric and a set of previous air quality metrics;
- store the average air quality metric in the memory;
- and
- generate an air filter type recommendation based on the average air quality metric.
A method for recommending filter types to be used in an HVAC system of a building comprising:
- obtaining, by one or more sensors, a measurement of air quality within the building;
- calculating, by a control device, a current air quality metric based on the measurement;
- calculating, by the control device, an average air quality metric based on the current air quality metric and a set of previous air quality metrics;
- and
- generating, by the control device, an air filter type recommendation based on the average air quality metric.
