System and method for controlling an airflow supplied to a cabin of a work vehicle

A work vehicle, comprising:

• a cabin;
• and
• an airflow control system comprising:
• a housing;
• a mixing chamber defined by the housing and comprising a fresh air inlet, a first recirculated air inlet, and a mixed air outlet, the mixing chamber being configured to receive fresh air via the fresh air inlet and recirculated air via the first recirculated air inlet, the fresh air being mixed with the recirculated air within the mixing chamber to create a fresh/recirculated air mixture that is supplied through the mixed air outlet,
• a recirculating chamber defined by the housing and isolated from the mixing chamber, the recirculating chamber comprising a second recirculated air inlet and a recirculated air outlet, the recirculating chamber being configured to receive recirculated air via the second recirculated air inlet and supply the recirculated air through the recirculated air outlet;
• a first blower coupled to the mixed air outlet of the mixing chamber and configured to blow the fresh/recirculated air mixture from the mixing chamber into the cabin;
• a second blower coupled to the recirculated air outlet of the recirculating chamber and configured to blow the recirculated air from the recirculating chamber into the cabin;
• a gate movable relative to the first recirculated air inlet to adjust an amount of recirculated air supplied to the mixing chamber;
• and
• an actuator configured to actuate the gate relative to the first recirculated air inlet.

A method for adjusting the proportion of recirculated air to fresh air received within an airflow control system for subsequent delivery to a cabin of a work vehicle, the airflow control system comprising a housing defining a mixing chamber and a recirculating chamber, the mixing and recirculating chambers being isolated from each other, the mixing chamber comprising a fresh air inlet and a first recirculated air inlet, the mixing chamber being configured to receive fresh air via the fresh air inlet and recirculated air via the first recirculated air inlet, the recirculating chamber comprising a second recirculated air inlet through which it is configured to receive recirculated air, the airflow control system further comprising a gate movable relative to the first recirculated air inlet to adjust an amount of recirculated air supplied to the mixing chamber, the method comprising:

• supplying an airflow exhausted from an outlet of the mixing chamber into the cabin of the work vehicle;
• supplying an airflow exhausted from an outlet of the recirculating chamber into the cabin of the work vehicle;
• receiving, with a computing device, airflow data indicative of an airflow parameter associated with operation of the airflow control system;
• and
• actuating, with the computing device, the gate relative to the first recirculated air inlet to adjust an amount of recirculated air received within the mixing chamber via the first recirculated air inlet based at least in part on the airflow data.
