Abstract
A filter section of a heating, ventilation, and air conditioning (HVAC) system includes a plurality of filters arranged in series relative to a flow path of air through the filter section. The plurality of filters includes at least one movable filter transformable between an extended position arranged within the flow path of air and a retracted position removed from the flow path of air. At least one movement mechanism is operably coupled to the at least one movable filter to transform the at least one movable filter between the extended position and the retracted position.
Claims20
A filter section of a heating, ventilation, and air conditioning (HVAC) system comprising:
- a plurality of filters arranged in series relative to a flow path of air through the filter section, the plurality of filters including at least one movable filter transformable between an extended position arranged within the flow path of air and a retracted position removed from the flow path of air;
- and
- at least one movement mechanism operably coupled to the at least one movable filter to transform the at least one movable filter between the extended position and the retracted position.
A heating, ventilation, and air conditioning (HVAC) system comprising:
- a filter section configured to receive air, the filter section including at least one movable filter transformable between an extended position arranged within a flow path of the air and a retracted position removed from the flow path of the air;
- at least one sensor for monitoring an air quality of the air;
- and
- a controller operably coupled to the at least one sensor and to the at least one movable filter, wherein the controller is configured to move the at least one movable filter between the extended position and the retracted position in response to the air quality of the air.
A method of adjusting a configuration of a filter section of a heating, ventilation, and air conditioning (HVAC) system comprising:
- sensing an air quality of a flow of air upstream from the filter section;
- identifying at least one of a plurality of movable filters to apply to the flow of air to achieve preset air quality limits of the HVAC system;
- and
- moving the at least one movable filter identified into the flow of air.
