  • Ventilation and drying system and method of using the same
    Patent number: 11209185
    Abstract: An air handling system includes a housing, a blower, a sensor, an air intake valve, and a controller. The housing includes an outlet to a passenger compartment, a fresh air inlet providing fresh air into the housing and a recirculated air inlet that guides air flow from the passenger compartment into the housing. The blower moves air through the housing. The air intake valve moves between a closed position blocking air flow from the fresh air inlet into the housing and an open position unblocking air flow from the fresh air inlet into the housing. The controller positions the air intake valve relative to the fresh air inlet controlling the flow of fresh air into the housing and thereby maintaining moisture density of the air flow entering the passenger compartment within a prescribed range based on humidity and temperature values from the sensor.
