Abstract
A booster fan system for a duct network connected to an HVAC unit includes: (a) a booster fan unit installable in the duct network adjacent a duct register, the booster fan unit including at least one blower and at least one temperature sensor; and (b) a control system for controlling operation of the at least one blower based on a prediction model configured for estimating an operational state of the HVAC unit based on sensor data received from the temperature sensor and the operational state determined for the HVAC unit during preceding HVAC cycles.
Claims20
A booster fan system for a duct network connected to an HVAC unit, comprising:
- a) a booster fan unit installable in the duct network adjacent a duct register, the register open to a room for climate control via the HVAC unit, the booster fan unit including at least one blower for moving air between the room and the duct network through the register and at least one temperature sensor for monitoring temperature adjacent the register;
- and
- b) a control system for controlling operation of the booster fan unit, the control system including at least one processor configured to:
- i) continuously receive sensor data from the at least one temperature sensor relating to the temperature adjacent the register;
- ii continuously determine an operational state of the HVAC unit using a prediction model configured for estimating a current operational state of the HVAC unit based on the sensor data and the operational state determined for the HVAC unit during preceding HVAC cycles;
- and
- for each HVAC cycle, update the prediction model with the current operational state predicted for the HVAC unit for that HVAC cycle;
- and
- iv) control operation of the blower of the booster fan unit during each HVAC cycle based at least in part on the operational state determined for the HVAC unit for that HVAC cycle.
A booster fan system for a duct network connected to an HVAC unit, comprising:
- a) a booster fan unit installable in the duct network adjacent a duct register, the register open to a room for climate control via the HVAC unit, the booster fan unit including at least one blower for moving air between the room and the duct network through the register and at least one temperature sensor for monitoring temperature adjacent the register;
- and
- b) a control system for controlling operation of the booster fan unit, the control system including at least one processor configured to:
- i) continuously receive sensor data from the at least one temperature sensor relating to the temperature adjacent the register;
- continuously determine an ambient temperature in the room using a prediction model configured for estimating a current ambient temperature in the room by applying the sensor data to a temperature model correlating the temperature adjacent the register to the ambient temperature in the room during and between HVAC cycles of the HVAC unit;
- and
- iii) control operation of the blower of the booster fan unit based at least in part on the ambient temperature determined for the room.
